Повний текст джерелаThe mechanical deformation of sedimentary rocks can give rise to the formation of compaction bands which can significantly affect the performance of geosystems. The objective of this thesis is to identify the formation of compaction bands in porous carbonate rocks in laboratory experiments and to propose a constitutive model based on second-gradient plasticity theory to account for the effect of local heterogeneity.Axisymmetric compression tests are combined with X-Ray Computed Tomography observations. Samples are imaged before and after several loading steps and at different confining pressure levels. Digital Volume Correlation technique is applied on consecutive images to build 3D deformation maps at a millimetric gauge length, which permit to identify strain localization zones. A simple method based on kinematic considerations is proposed to classify these zones. Compaction bands have been identified at high confining pressures, pure shear bands are obtained for low confinements whereas compactive shear bands are observed in the transitional regime. In contrast, a diffuse compaction occurs in hydrostatic loading conditions. 3D porosity maps are constructed at some intermediate meso-scale and superimposed on deformation maps. The heterogeneity of porosity is found to control the pattern of compaction bands, as they lay inside high-porosity zones and avoid denser zones. Grain crushing is identified as the main micromechanism of the deformation. Very fine particles fill the pores and induce a porosity reduction. Large pores are observed to remain intact in denser zones, as they are protected by a surrounding rigid lattice of cemented grains. When shear strain is identified in deformation bands, porosity heterogeneity is found to control the volumetric behavior. Along a compactive/pure shear band, some cracks are observed in denser zones, whereas grain crushing and pore filling are observed in the more porous zones. These mechanisms are responsible for a complex co-existence of local contractancy and dilatancy along shear bands.Standard constitutive elastic-plastic laws of homogeneous media are insufficient to model correctly compaction banding, as a zero-thickness band is obtained for rate-independent materials in a Cauchy continuum. To regularize this problem, higher-order continua (micromorphic media) can be considered, where internal lengths in relation with the microstructure are introduced in the constitutive relations. A particular issue of these models is to calibrate the higher-order parameters. In the framework of second-gradient plasticity theory, the yield surface depends on a hardening parameter, related to the plastic strain and its second gradient. The plastic porosity reduction is taken here as the hardening parameter. A calibration procedure of the additional higher-order parameters based on macroscopic mechanical data and the data provided by the X-Ray images is proposed. Once the model is calibrated, a linear stability analysis in axisymmetric triaxial loading is applied to predict the formation of compaction bands. The calibrated model is subsequently implemented in a finite element code, textit{Numerical Geolab}, to perform numerical simulations of the experiments. Numerical results are finally compared to the experimental observations

Повний текст джерелаDeformation bands are geological structures that occur in porous and granular material presenting a high porosity (>15%). These structures can be identified as compactive or dilatant, a shear component is also often observed. At the microscopic scale, it is possible to observe a grain rearrangement and an intense compaction and or shearing can lead to grain crushing (known as cataclasis), to form a thin deform zone that will modify the porosity and permeability of the rock. Deformation bands have a non-negligible impact on fluid flow, creating a barrier or a drain in the potential reservoir. The formation of such structures is mainly linked to the tectonic activity but also to the facies and other sedimentological parameters of the host rock. The understanding and the prediction of the occurrence and distribution of the bands is the main objective of this thesis.In this study we analyzed a deformation band site found in the Tremp basin, in the Aren formation localized in the South Central Pyrenean Zone. We defined the nature of these structures with macro and microstructural analysis and by adding a study of the magnetic anisotropy to constrain the shortening direction responsible to the band formation. We evidence two major types of bands showing different orientations and behavior: (1) Pure compaction bands (PCB), perpendicular to the shortening and (2) Shear enhanced compaction bands (SECB), oblique to the same shortening.In comparison with tectonic schedule in the studied area and time vs. burial data of the formation, we deducted that both types of bands took place at a shallow burial (<1km depth), which means short times after deposition. This localized deformation, showing mainly cataclasis, is associated to the growth of the Sant Corneli-Boixols fold and thrust belt. Such structures are not common at a shallow depth and we propose that the calcarenite facies of the host rock is the key factor to explain the band occurrence.Thereafter, we made analytical simulations based on geomechanical experimentations results that allowed us to constrain the stress state and orientations needed to create these structure and to determine the timing of formation compared to the burial of the layers during the growth of the Boixols thrust. The stresses magnitudes are expected to be really low in the case of an early deformation.Finally, we tested and compared our observations and hypothesis to numerical modeling where we analyzed the impact of the growth of a fold and thrust belt on the stress state and orientations and the analysis of potential deformation bands occurrence. The stress distribution and the potential occurrence of deformation bands in a porous reservoir presenting different characteristics and located in front of this fold were studied.With the modelizations results, we exposed that our hypothesis of shallow deformation bands are dependent from the position of failure envelopes (that are dependent on the rock lithology). To explain the band formation we studied in this thesis, a weak mechanical strength of the host rock is needed to form deformation bands at less than a depth of one kilometer. The pure compaction bands are associated to a potentially early layer-parallel shortening (LPS)

Повний текст джерелаThis PhD thesis presents a laboratory study aiming at a better understanding of the stress-strain response of the Vosges sandstone (porous rock) tested at a range of confining pressures (i.e., 20-190 MPa) and different axial strain levels. Localised deformation was captured at different scales by a combination of full-field experimental methods, including Ultrasonic Tomography (2D), Acoustic Emissions (3D), X-ray Tomography (3D), and 3D volumetric Digital Image Correlation, plus thin section and Scanning Electron Microscope observations (2D). These experimental methods were performed before, during and after a number of triaxial compression tests. The combined use of the experimental techniques, which have different sensitivity and resolution, described the processes of shear band and shear-enhanced compaction band generation, which formed at low to intermediate and relatively high confining pressures, respectively. Pure compaction bands were not identified. The deformation bands were characterised as zones of localised shear and/or volumetric strain and were captured by the experimental methods as features of low ultrasonic velocities, places of inter- and intra-granular cracking and structures of higher density material. The two main grain-scale mechanisms: grain breakage (damage) and porosity reduction (compaction) were identified in both shear band and shear-enhanced compaction band formation, which presented differences in the proportions of the mechanism and their order of occurrence in time

Повний текст джерелаEn aquesta tesi, estudiem les famílies d'interpolació i sampling (mostreig) en espais de funcions de banda limitada en varietats compactes. Les nocions de sampling i interpolació juguen un rol fonamental en problemes com ara recuperar un senyal continu a travès de les mostres discretes. Aquestes dues nocions són, en part, de caràcter oposat: un conjunt de sampling ha de ser suficientment dens per tal de poder recuperar la informació i, en un conjunt d'interpolació, els punts han de ser suficientment separats per tal de poder trobar una funció que interpola certs valors. A grans trets, una successió de sampling per a un cert espai de funcions és una successió de punts {lambda(n)}(n) tals que la norma de tota funció “f” de l'espai és equivalent a la norma de la successió que resulta d'avaluar la funció en els punts {lambda(n)}(n). Donada una varietat compacta M de dimensió m>/= 2, considerem el subespai E(L) de L(2)(M) generat per vectors propis del Laplacià de valor propi més petit que L > 0. Aquests espais s'anomenen espais de funcions de banda limitada i són el principal motiu d'estudi de la tesi. Els espais E(L) comparteixen propietats amb els espais clàssics de Paley-Wiener i la tesi explora aquesta connexió. La tesi s'estructura en quatre capítols. En el primer capítol, introduïm el context del nostre problema i els resultats principals provats al llarg d'aquesta tesi. També descrivim el comportament asimptòtic del nucli reproductor i la construcció de nous nuclis associats als nostres espais amb un decaïment fora de la diagonal. A més a més, expliquem algunes eines que jugaran un paper fonamental en les proves dels nostres resultats. En el segon capítol, estudiem el problema del sampling continu. El rol d'una família discreta de sampling el realitza una successió de conjunts en la varietat anomenada successió de Logvinenko-Sereda. Un problema més dèbil és trobar una caracterització de les mesures de Carleson. Aquesta qüestió també s'ha resolt en termes d'una condició geomètrica. En el tercer capítol, provem algunes condicions (qualitatives) necessàries i suficients per a la interpolació i sampling. Definim l'anàleg a la densitat de Beurling-Landau i provem, seguint les idees de Landau en el context dels espais de Paley-Wiener, condicions quantitatives necessàries per a què una família sigui de sampling o d'interpolació. En el quart capítol, donem una aplicació dels resultats de densitat obtinguts en el Capítol 3. Estudiem les famíllies de punts de Fekete en varietats compactes amb certa propietat. Els punts de Fekete són punts que maximitzen un determinant del tipus Vandermond que apareix en la fòrmula d'interpolació del polinomi de Lagrange. Són punts adients per les fòrmules d'interpolació i la integració numèrica. Els punts de Fekete tenen la propietat que són casi d'interpolació i sampling. Per tant, aquest tipus de punts estan ben distribuïts en la varietat ja que contenen informació suficient per recuperar la norma L(2) d'una funció de banda limitada i, són suficientment separats per tal d'interpolar alguns valors fixats.
