| 摘 要： | 为了预测超深储层物性,采用超深储层孔隙度测井曲线数据,应用地质统计学,即实验变差函数来计算不同深度下孔隙度实验变差函数值,并拟合出孔隙度随油气藏埋藏深度连续变化关系表达式,总结了超深层油气藏储层岩石孔隙度随油藏埋藏深度或有效覆压的变化规律。同时,通过数学计算,对孔隙度进行处理和分析,建立了不同埋藏深度下超深层油气藏孔隙度随深度变化的宏观模型。该研究对深入了解超深层油气藏的产能及预测超深层油气藏的开发动态和采收率具有一定意义。

| Abstract: | Ultra-deep reservoir quality is predicted by using porosity log and geostatistic method to calculate the experimental variation function of porosity at different depths,and by producing an expression of the variation of reservoir porosity with burial depth.The variation of ultra-deep reservoir porosity as a function of burial depth or effective overburden pressure has been generalized.Meanwhile,a mathematical model of porosity change with depth has been established.This study provides reference to understan... |
