摘要
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。根据各油田有代表性的高压物性资料,采用多项式的方法对实测点进行拟合,得出原油的高压物性与地层压力之间以及各参数间的相互关系式。同时给出了其他常用参数的确定方法。
<abstract> 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. The interrelations between the high pressure physical properties and formation pressure, and among each parameter are obtained by using the polynomial method in matching experimental points based on the representative high-pressure oil physical properties in each oilfield. The method for determining other common parameters is given at the same time.
