此文在分析多层双孔介质油藏渗流规律的基础上,考虑各层具有不同的物性参数和原始地层压力,建立了考虑井储和表皮影响的无窜流多层双孔介质油藏渗流模型。通过Laplace变换,求解得到了拉氏空间内的井底压力和各层产量的解析解,并根据数值反演方法编程绘制了各层产量的理论变化曲线,分析了分层产量变化的规律及影响因素。此文的研究结果可以指导现场的油井合理配产。
Based on the analysis of seepage law of multi-layer two-hole reservoir, considering the different physical parameters and initial formation pressure of each layer, the seepage-free multi-layer two-hole reservoir with seepage and influence of well surface is established model. Through the Laplace transform, the analytical solution of the bottom hole pressure and the output of each layer in Laplace space is obtained. According to the numerical inversion method, the theoretical curve of the output of each layer is drawn and the regularity and influence of the variation of the layered output are analyzed factor. The result of this paper can guide the rational allocation of oil wells on site.
