摘要: 常规方法确定地层原油体积系数往往把原油压缩系数视为常数,实际上原油压缩系数与地层压力成反比,因此常规方法计算超深油藏的地层原油体积系数有较大误差或根本不合理。推导了采用等效压缩系数计算地层原油体积系数的精确公式,并进行了实例计算。

Abstract: Fornation oil volume factor calculated with conventional method has bigger error is imreasonable because oil compressional factor is regarded as constant. In fact, oil compressional factor is in inverse proportion to fornation pressure, so we derived an accuracy formula for calculating formation oil volume factor by adopting equivalent compressional factor, and provided case history with it.
