Abstract:
AbstractDetermining the expected age at a potential ice-core drilling site on a polar ice sheet generally depends on a combination of information from remote-sensing methods, estimates of current accumulation and modelling. This poses irreducible uncertainties in retrieving an undisturbed ice core of the desired age. Although recently perfected radar techniques will improve the picture of the ice sheet below future drilling sites, rapid prospective drillings could further increase the success of deep drilling projects. Here we design and explore a drilling system for a minimum-size rapid-acces

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.

AbstractMore than 170 years ago, Louis Agassiz, one of the creators of glacial theory, made his first attempt to drill into the bed of Unteraargletscher, Swiss Alps. Since that time, various systems for thermal and mechanical drilling have been designed especially for boring into ice, and some conventional drill rigs been adopted for ice coring. Although contemporary ice-drilling knowledge and techniques are now familiar, there remain many problems to be solved by advanced modern technology.

Abstract:
The magnetic bar-code on the ocean floor provides convincing evidence of moving continents, yet, as with the discovery of the structure of DNA, few are convinced—at first. Drilling in the deep oceans and geochemical work at mid-ocean ridges provides further evidence in support of the Vine–Matthews Hypothesis. Application of the hypothesis to data collected in the Pacific and Atlantic Oceans establishes sea-floor spreading as the process that creates new oceans and, in conjunction with reversals of the geomagnetic field, stamps the bar-code into the rocks beneath the sea bed.

The RS computation is performed by measuring the strains relaxed on surface and then by combine properly such measured strains with the influence coefficients previously computed accurately by using a n

Abstract The problem of wellbore instability is a worldwide technical problem in the field of the drilling engineering and one of the core problems for the safe and efficient drilling. After the drill bit drills the formation and a borehole is formed, the drilling fluid column pressure replaces the support provided by the drilled rock stratum, upsetting the original stress balance of the formation, and causing the stress redistribution of the rock around the borehole. If the redistributed stress exceeds the maximum load that the rock can bear, it will lead to wellbore instability. At the same
