回归分析方法在大庆葡西地区地层压力预测上的应用

Regression Analysis and Its Applications in Formation Pressure Forecast in Puxi Area, Daqing

本文根据数理统计分析 ,应用渗流力学理论 ,结合油田实际生产资料 ,得出大庆探区西部葡西地区各压力系统的地层压力预测公式 ,经实际资料验证 ,相对误差在 0 .2 7～ 4 .89%之间 ,效果较好 ,有力地指导了油田钻井、固井、射孔和试油等项工作。

Based on mathematical statistics analysis and seep mechanics theory, the formation pressure forcast formulas are determined in pressure systems of Daqing Xibu Puxi area using the practical production data of oilfield. Relative error is between 0.27% and 4.89% by practical data testing and verifying, which proves that the method proposed in this paper achieves good results. It guides the well drilling, well cementing, perforating and well testing effectively.
