Abstract:

This paper describes the wear characteristics of impregnated diamond bits when drilling in Al2O3 armor ceramic. With different bits being developed, drilling experiments and scanning electron microscope (SEM) examinations were conducted, and the results show that diamond wear types consist of complete crystal shape, micro fragmentation, whole fragmentation, wearing flat and falling off of diamond; abrasive wear, impact abrasion and erosion exist in the wear of diamond and bond; diamond grain size and concentration have their optimal value under fixed machining conditions; diamonds of high quality could increase bit drilling efficiency and serving life; the bit whose abrasion rate of bond matches that of diamonds presents the best comprehensive properties.

Abstract:

Impregnated diamond core bits are often used in core drilling for geological surveys. A tri-state theory is proposed to describe the three states in drilling processes for a diamond particle or a bit. These states are contacting state, cutting state, and ploughing state. Furthermore, the relations among thrust and other mechanical parameters are also summarized. The optimal value of the specific energy is in the cutting state. Several experiment results verified the proposed model. This mechanism is useful for selecting operation parameters in core drilling using impregnated diamond core bits.

Abstract:

The diamond impregnated bit matrix should not only wrap the diamond up firmly; also constantly wear in the drilling process to ensure that the diamond can be made exposure constantly. The wear of diamond impregnated bit matrix is the key to affect the exposure of diamond blade.In this paper, based on the tribology, the wear mechanism of drill bits matrix is analysed from the microscopic view.Then,the relationship between matrix hardness and abrasion resistance can be obtained.

Abstract:

To solve the mentioned problem of accelerated commissioning of minerals occurring in hard rocks, studies have been carried out to formulate the following recommendations for the creation of high-performance diamond bits: - the crown matrix should contain several (five or more) impregnated diamond-bearing layers in height, separated by diamond-free layers of significantly lower hardness (for example, VK-20 hard alloy); - each diamond impregnated layer of the matrix must have a "comb" profile, representing annular wedge-shaped protrusions and depressions; - the impregnated diamond layers of the matrix during drilling should be equally loaded along the radius of the bit, which makes it possible to increase the wear resistance of the tool and reduce the number of rough diamonds for the manufacture of the latter; - to maintain the diameters of the well and the drilled core, the inner and outer side surfaces of the matrix must be equipped with wear-resistant diamond inserts (for example, from tvesala); - to produce a high-quality wear-resistant matrix, small amounts of various components should be added to the composition of the binder of the 94WC + Co + Cu type diamond grains. Recommendations 1-4 are embodied in the design of diamond impregnated crowns, for which the Republic of Kazakhstan has received patents. Crowns have been introduced into production with a significant effect. A diamond crown has been developed and patented, the impregnated layers placed in a matrix on a three-start helical surface with a slight pitch of 0.8 - 1.2 mm. It is expected that with this design, the pre-fracture zone will be involved in the bottom hole destruction process, which lies under the intrusion zone and represents a hard rock broken and weakened by cracks to a depth ten times greater than the intrusion depth of diamond grains. An experimental batch of multilayer crowns with an equally loaded comb profile and placement of impregnated layers on a three-start helical surface was made using software and CNC (numerical control) machines.

Abstract:

Diamond particle with tungsten boride (WB) coating was synthesized by the molten salt method. Three different diamond/Fe-Ni composites made from pristine diamond, B4C coated diamond and WB coated diamond with Fe-Ni powders were prepared by powder metallurgy. The composition and microstructure of the tungsten boride coating were investigated. Both bending strength and cutting performance of the composites were investigated. Addition of the WB coating provided an increased bending strength (871.2 MPa) and relative density (93.54%), compared with the composites consist of uncoated diamond and Fe-Ni (746.8 MPa, 92.81%). Three different Fe-Ni-based impregnated diamond drill bits contained 20 vol.% pristine diamond, B4C coated diamond and WB coated diamond were manufactured by powder metallurgy, respectively. Drilling rate of bits was measured by XY-4 geological core drill on granite. The test results show that the drilling rate of bits with WB coated diamond (2.42 m/h) was 40% higher than that with pristine uncoated diamond (1.72 m/h).

Abstract:

Igneous rocks of Junggar Basin are hard, strong abrasive and poor drillability. ROP is low in drilling these rocks, and drilling cycle is long, which seriously affect the process of exploration and development in the Carboniferous reservoir. Considering the igneous rock formation characteristics and the drilling problems, using PDC impregnated diamond high strength, super abrasion as the main rock breaking device, a new type of cutting and grinding of diamond impregnated bit was developed. This bit has the following characteristics: Compound cutting structure with blades and cylindrical Impregnated cutters; big nozzle in the center + deep radiation water slot hydraulic structures; Natural diamond and TSP lengthened gauge design; Selection of 40/50 mesh diamond grit, mix two kinds of inserts with diamond concentration 70%.The bit has the combination of impregnated bit and PDC drill bit technical advantages, which improve the bit adaptability to the formations. Hassan3 Carboniferous igneous formations field test shows that: average ROP is 0.71m / h, single bit footage is 86.5m, which increased by about 20% and 302% respectively compared with high efficient three-roller bits. The success usage of this bit in Hassan 3 provide an effective means for high quality fast drilling in Junggar Basin igneous rock formation.

Abstract:

The impregnated diamond composites are widely used for rock drilling and the processing of construction materials. In order to decrease the sintering temperature so as to reduce the thermal damage of diamond, and ultimately improve the sharpness of the diamond tool, the iron-nickel pre-alloyed powder sintered specimens and the impregnated diamond composites were prepared by powder metallurgy. The microstructure and phase composition of specimens were characterized by SEM and EDS. The effect of sintering temperature and the content of WC particles on the mechanical properties of the specimens, such as relative density, hardness, bending strength and wear resistance were investigated. The results showed that the relative density, hardness and bending strength of the sintered specimens increased first and then decreased with the sintering temperature changing from 700 °C to 900 °C. The performance of the specimens sintered at 800 °C was the best, with the corresponding values of 97.75%, 24.0 HRC and 2114.87 MPa. The optimum content of WC was 30wt%, and the grinding ratio reached to 424.11. The rate of penetration of drilling bits with iron-nickel pre-alloyed based matrix increased by 91.14% compared with the traditional bits which used 663Cu-Co-Ni-Mn as binder.

Abstract:

The article presents the results of research on the creation of drill bits with high durability and sufficient productivity when drilling hard rocks. Four areas of research have been identified to solve this problem: the crown must be multilayer, the profile of the diamond-bearing layers must represent annular conical protrusions and cavities; diamond layers should be separated by diamond-free layers of lower hardness and experience uniform specific pressure during operation; the design of the bit should take into account the peculiarities of the rock destruction mechanism under the action of diamond grains; the manufacturing technology of the crown matrix must be perfect. Only defect-free diamonds obtained by sorting with special methods are involved in the creation of the matrix; Adding CrB2 or VN nanopowders to the composition of the charge makes it possible to improve the quality of the matrix structure, all tribiological and operational properties, and due to the preliminary metallization of high-strength synthetic diamonds, a transition zone “diamond-coating-matrix material” is created, which will significantly increase the wear resistance of diamond rock cutting tools. The mentioned problems have been partially solved: a multilayer impregnated bit with a ridged profile of diamond-bearing layers and a uniform specific pressure on the latter during drilling has been created and put into production, laboratory studies have been carried out to improve the quality of composite materials with positive results, further research is being carried out in all other areas.

Abstract:

The use of large single crystals of diamond, grown by HP-HT with the latest technologies in drilling tools, can improve the productivity of the drilling process, increase the penetration rate, reduce wear of the main matrix, and provide a safe working environment when drilling solid rocks.For an informed choice or design of the working part of the drilling equipment, an analysis of the functional purpose is important.The main role here is played by the factor of complexity of geodetic conditions: the angle of drilling, fracture toughness and class of rocks, their changes with the depth of drilling.Analysis of studies and publications on functional analysis showed that diamonds should not only have high hardness and static strength, they should have a high value of thermal strength and chemical resistance, which will allow them to be used with sufficient efficiency when developing wells in difficult geological conditions. However, the main indicator of the suitability of such single crystals is still strength. It has been experimentally proven that the main type of diamond wear during drilling is partial or complete chipping of the protruding part of the crystals. Thus,the bits are equipped with harder diamonds, they will allow to process harder rocks without chips, reduce wear of the matrix itself, provide higher drilling speeds alongwith a decrease in energy consumption and consumption of consumables, for example, drilling mud.The purpose of the article is to analyze the effect of chemical-thermal exposure, as an integral part of the technological process of manufacturing drill bits, on the tensile strength of synthetic diamonds of octahedral habit type Ib obtained by HP-HT technology.Based on the data obtained experimentally, the work shows the suitability of synthetic diamonds as part of a functional cutting tool for drilling and geological exploration. The optimal size of crystals was determined, at which a sufficient level of strength is provided. The falling dependence of the strength on the edge length of the investigated diamond single crystals is graphically demonstrated.For the first time, the paper presents a study of the effect of chemical-thermal treatment as part of the technological process of manufacturing a drilling tool on the strength of non-magnetic single crystals of synthetic diamond type Ib. The presented materials can be used for a reasonable choice or design of drill bits impregnated with largesingle crystals for drilling and geological exploration.

Abstract:

Along with economic advancement, diamond bit is widely used in mine exploration and engineering geological investigation. To reduce the cost of impregnated diamond bit and improve its drilling efficiency in highly abrasive formation, this paper designs a diamond bit based on matrix weakening theory, and prepares the matrix from high-grade diamond abrasives and SiC particles. Through theoretical calculation, diamond bits were designed with six different formulas of diamond concentrations and weakened SiC particle concentrations. The theoretical analysis shows that the weakened SiC particle concentration fell within 0-50%; the number of diamond particles dropped from 750,115 to 375,150, saving the diamond cost by 50%. To further explore the life, drilling efficiency, and working mechanism of diamond bit, the apparent form of bit materials was analyzed through field tests, using EPMA-1720 electron probe microanalyzer and GENSIS60 energy spectrometer. The field tests show that: the proposed bit, with 35% of matrix skeleton and 65% of bonding metal, improved the drilling efficiency of ordinary impregnated diamond bit by 68%, while reducing the service life by merely 30%. The apparent form analysis shows that: In the diamond bit designed by matrix weakening theory, the weakened SiC particles could easily fall off the matrix surface, leaving recoverable pits on the surface. The non-smooth form weakens the abrasion resistance of the matrix, reduces the contact area between the crown of the drill bit and the rock surface at the hole bottom, and increases the pressure of the crown on the rock per unit area. The fallen wakened particles participate in the abrasion of the matrix at the hole bottom, improve the grinding ability of the rock powder at hole bottom, and promote the protrusion of new diamond particles in the matrix.

Abstract:

The methods of making diamond tools have undergone a fantastic development since the invention of the synthetic diamond in the mid-1950’s. Over time, new production techniques based on diamond tooling have been implemented into various areas of industrial activity enabling to do the job faster, more accurately and at less cost. The recent statistics indicate that the consumption of diamond abrasives reached an impressive volume of billion carats in 2000, as compared with 380 million carats in 1990 and 100 million carats in 1980. In the new millennium the market for diamond tools continues to grow rapidly. The present decline in the price of industrial diamond makes it a commoditised product capable of competing with conventional abrasives. In terms of production volume, by far the largest group of diamond tools comprises the metal-bonded diamond impregnated tools, such as circular and frame sawblades, wire saws, and core drills for cutting natural stone and construction materials, and core bits for drilling in various rock formations. The objective of this article is to provide a compendious coverage of the PM diamond tool-making routes, and to identify the recent trends towards changing the tool design and composition to render it cheaper and more efficient.

Abstract:

AbstractAccording to the seafloor drill working conditions and the complex formation characteristics of the seafloor, this paper aims to improve the adaptability of the diamond bit to the formation and the coring quality. The cutter tooth design scheme of the impregnated diamond bit is proposed, and Fluent analyzes the flow field of drilling fluid at the bottom hole. The results show that the cone cutting tooth bit with the primary and assistant nozzles can directly avoid 85.33% drilling fluid flushing core and reduce the disturbance of drilling fluid to the core samples. The water passage structure of the bit is reasonable, and the upward return velocity of the drilling fluid can be stabilized between 0.7 and 1.8 m/s, which meets the requirements of the upward return of cuttings in seabed strata, and has a good hole wall protection performance. Based on the bottom-jet diamond bit, the assistant nozzles are added. The drilling fluid of the assistant nozzles can better cover the bit crown, conductive to cooling the bit crown. The drilling fluid of the main nozzles can timely up-return along the outer annulus hole wall, conducive to the up-return of the cuttings with drilling fluid. This study can extend existing designs of a seafloor coring bits and bottom hole flow field analysis methods.
