rock cavity

This paper analyses the relation of the variation of reservoir rock pore volume, porosity and compressibility with the effetive overburden pressure,and basing on the polynomials regreasion of rock experimental data,it presents the calculating.

本文分析了油藏岩石孔隙体积、孔隙度、压缩系数随压力的变化关系，并在实验数据的多项式回归基础上，提出了地层条件下岩石石孔隙度、平均与瞬时孔隙体积压缩系数的计算方法，经过对中原、新疆、四川等油气田岩石测试数据处理的实践验证，说明这些方法具有准确、便于计算等优点。
