| 摘 要： | 通过对F油藏孔隙体积压缩系数实验数据的分析,提出采用二元二次多项式形式表述孔隙体积压缩系数与孔隙度、净有效压力的关系,给出了常压基质型灰岩储层和异常高压基质型灰岩储层孔隙体积压缩系数的拟合方程,并引入概率法确定岩石压缩系数；基于上述研究分析了孔隙体积压缩系数变化规律.本文研究对同类油藏的开发研究具有一定的指导意义.

| Abstract: | By analyzing the experimental data on pore volume compressibility in F oil reservoir,it was proposed that quadratic multinomials with two variables can be used to describe the relationships of pore volume compressibility with porosity and net effective pressure,a match equation of pore volume compressibility was given for normal pressure and abnormally high pressure matrix limestone reservoir respectively,and the rock compressibility was determined by introducing a probability method.The variations in pore ... |
