volume compressibility

Order to improve the precision of well test interpretation, according to the fluid properties and the present development situation of the developed Shengli oilfields, oil volume factor, oil compressibility, viscosity and the PVT parameters used in well test interpretation are determined.

为提高试井解释精度，针对胜利油区已开发油田的流体性质和开发现状对试井解释中的原油体枳系数、原油压缩系数、粘度等PVT参数进行了确定。

With the experimental values of thermal pressure coefficients of liquids to modify the excluded volume in the original van der Waals equation, an augmented van der Waals compressibility factor applicable to high density fluids is obtained.

利用实验测得的液体的热压力系数，修正原始van der waals模型中的排斥体积，得到了一个适用于高密度流体的推广的van der waals压缩因子。
