... ), can be calculated by the program without an expert's manual rating. To identify major outcrop joint surfaces, the random sample consensus algorithm was employed. Subsequently, we calculate the weighted joint density ( wJd ) and its corresponding RQD based on the major joint surface. The spherical K...

Furthermore, if plasticity, sliding along a fracture or joint, and dilatancy occur, the shear component of the stress tensor should...

... mechanisms of gas-water two-phase flow in shale nanopores, a gas-water two-phase flow model during fracturing flowback of shale reservoirs is established. However, it requires many iterative calculations, and does not consider the oil-gas two-phase flow, and the actual application effect is poor. In summary...
