裂缝性油藏流入动态模型研究

Inflow performance model for fractured oil reservoir

在列宾逊函数的基础上 ,将变形介质渗流理论应用于裂缝性油藏流入动态研究 ,利用油田实际生产数据 ,得到油藏压力与变形系数的函数关系式。这样使原有的裂缝性油藏流入动态的数学模型得到改进 ,也完善了裂缝性油藏流入动态的计算方法。计算结果与实测结果对比表明 ,改进模型的计算误差一般在 3%以内 。

The flow theory for variable medium was applied to evaluate inflow performance of oil in fractured reservoirs. On the basis of the in-situ data, a function relation of pressure with deformation coefficient of reservoir was developed and employed to build a modified mathematical model. A comparison between the prediction results and test data indicates that the computational error of the modified model is less than 3 percent. This model can greatly enhance the prediction precision of well productivity.
