摘要
本文详尽的介绍了在Ansys软件平台下裸眼完井和射孔完井有限元三维模型的建立及网格划分方法。用热流场模拟渗流场,用无限大导热材料模拟井筒和孔眼,可以很好的模拟射孔完井渗流场。利用所建模型分析了裸眼完井和射孔完井的渗流场速度分布,分别得出了其出口处的面流量,然后计算了产率比。另外编写了APDL语言,可以方便的修改射孔完井参数和地层参数,以更快捷的方式来预测产率比。
The article tell the method that set up borewell completion well finite element of threedimensional model and perforation completion well finite element of threedimensional model and the method of dividing grids on Ansys software platform. That using the field of thermal flux to simulate the field of transfusion and that using the material of infite conductity to simulate the well hole and the perforation hole t can be very good. Based the building models analyse the distribution of transfuse field the bore well completion well and the perforation completion well, and calculate the discharge and production rate. In addition ,I write APDL language ,and it can modify the perforation well parameter and sequence parameter conveniently ,and predicte production rate quickly.
