原油体积系数

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。

Formation oil volume factor calculated with conventional method has bigger error or is unreasonable because oil compressional factor is regarded as constant .

从容积法计算储量的公式可以看出，影响储量计算的因素有含油面积、油层有效厚度、有效孔隙度、含油饱和度、地面原油密度、原油体积系数等。
