The factors including clay content &calcite cement have an important effect on the stress sensitivity of low-permeability rocks. 粘土总量和有无方解石胶结对低渗透岩石压敏效应的影响更为显著。
A pressure-sensitive effect affects unfavorably the production performance of fractured low-permeability reservoirs with horizontal fractures. 压敏效应对含水平裂缝的低渗透油藏开发具有重要影响。
