摘　　要：由于岩石的应力敏感性与岩石孔隙压缩系数有关,在油田开发中,岩石孔隙体积压缩系数和岩石压缩系数不能混淆。岩石的压缩系数较岩石孔隙体积压缩系数小,国内外许多学者通过实验已经证实,低渗透储集层比中高渗透储层有较强的应力敏感性,生产过程中不可将其忽略。同时,文章强调指出:实验是科学研究中一门基础科学,而且是检验真理的唯一标准。低渗透储层存在应力敏感性和启动压力是一种客观存在的科学现象,不属于一种实验假象;油气运移是学说而不是理论,油气运移的一些认识人们无法在实践中证实。The stress sensitivity of rock is related to the pore compressibility,so that the compressibility of rock pore volume cannot be confused with the rock compressibility in oilfield development. Rock compressibility is smaller than pore volume compressibility. It has been proved through experiments by many researchers in the world that low permeability reservoirs are more stress-sensitive than medium-high permeability reservoirs; this cannot be ignored during production process. Meanwhile,this paper emphasizes that: experiment is a basis of scientific research,and is the sole criterion for testing truth. Low permeability reservoirs are stress-sensitive; the threshold pressure does exist in low permeability reservoirs and is not an experimental false; oil and gas migration is a doctrine but not theory; some cognition about oil and gas migration cannot be verified in practice.
