Abstract A series of triaxial compression tests were conducted in order to investigate the mechanical behavior gas‐saturated methane hydrate‐bearing sediments, and a comparison was made between water‐saturated specimens. Measurements on specimens indicate that (1) larger hydrate saturation, failure strength more apparent shear dilation behavior; (2) stiffness increase with increasing effective confining stress pore pressure applied during compression, though specimen becomes less dilative...
Summary Gas permeability in hydrate reservoirs is the decisive parameter determining gas production efficiency and of hydrate. In South China Sea (SCS), flow tight natural (NGH) silty clay significantly affected by slippage effect effective stress (ES) overlying rock. To improve effectiveness exploitation, it necessary to understand influence on evolution law. For this paper, characteristics methane montmorillonite sediments were studied at different pore pressures ESs. Experimental data...
We experimentally demonstrated that the microsphere can discern details of object whose sizes are below conventional diffractive limit and such super-resolution capability be reinforced if semi-immersing corresponding microspheres in liquid droplet, producing a sharper contrast comparatively smaller magnification factor. The is considered as channel connects near-field evanescent wave transmission one far field. A conjecture based on this proposed to explain mechanism phenomenon.
Abstract The macromechanical properties (strength, stiffness, stress‐strain relationship, etc) of the hydrate‐bearing sediment are often correlated with hydrate cementation failure behavior. In this study, a consolidated drained triaxial shear test X‐ray computed tomography was conducted on saturation 32.1% under 3 MPa effective confining pressure for revealing occurrences were clearly identified to be cementing, grain‐coating, prepatchy cluster and patchy cluster. behavior (morphology),...
Approximately 90% of gas hydrates are buried in fine-grained sediments, especially the South China Sea. The potential instability sediments induced by hydrate dissociation requires investigation shear strength and pore pressure response during recovery. To date, most studies have focused on undrained mechanical behavior hydrate–bearing sand or hydrate–free clay — few examined sediments. Because low-permeability water-saturated characteristics Sea, a series triaxial tests were performed...
