摘要
针对吉林油区 15个已开发油田的岩石、流体性质及开发现状对试井解释中的地层油体积系数、油压缩系数、粘度、溶解油气比、岩石压缩系数、地层水压缩系数等基础参数进行了确定。主要方法是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的关系式 ;同时根据实测岩石压缩系数采用多元回归方法 ,回归出松辽盆地南部及伊通地区的岩石压缩系数经验公式。
According to rock characteristics,fluid properties and the reservo ir development case,the fundamental parameters such as oil volume factor,oil com pression coefficient,viscosity,formation compression coefficient and water compr ession coefficient and determined.The main method is got a the relation ship be t ween the high pressure are the oil parameters by using the polynomial matching m ethod based on the present data in the oilfield.The relationships between the hi gh pressure and the oil parameters for the formation in the South Songliao Basin and Yitong region are got by matching the real test data.
