【摘要】 应用吉林油区现有的实际岩石压缩系数资料对前人的经验公式进行验证 ,得出总相对误差为 50 4 .2 5%～ 681 .1 5% ,由此发现这些经验公式对吉林油区并不适用。因此 ,提出了应用压力、孔隙度进行多元回归方法计算岩石压缩系数的方法 ,分别建立了吉林油区松辽盆地南部及伊通地区油藏岩石压缩系数的通用回归公式 ,并应用实际资料验证了此公式的可靠性。更多还原

【Abstract】 By using the former experiential formation of the rock compressibility,the result errors is about 504.25% to 681.15% .So we can conclude that the formation is not suitable for Jilin oilfield,A multiple regression analysis method for determiniug the rock compressibility based on the pressure and porosity is established.The normal regression formation for calating the rock compressibility in the south of Songliao basin and Yitong region is got.The reliability of the method is verified by the field real data.更多还原
