摘要
与窦宏恩先生讨论了低渗透储集层有无应力敏感性,岩石压缩系数,有效应力,启动压力梯度,孔隙度不变性原则等油藏工程中常遇到的一些基本概念及其数学表述。这些问题的正确解答,对储集层研究和油气藏开发具有重要意义。
Several questions about low-permeability reservoirs are re-discussed with Mr Dou Hong＇en,such as presence of stress sensitivity,rock compressibility,effective stress,starting pressure gradient,porosity invariance principle of reservoir engineering,which are frequently encountered basic concepts and mathematical representations.Correct answers to these questions are of great significance on the reservoir researches and rational development.
