【摘要】 采用点源函数的方法通过对水平井各种边界条件研究 ,提出了用试井模型来评价复杂边界条件下均质油藏水平井压力动态。通过该模型能够研究水平井在无限大油藏、一条断层、直角断层、渠道流断层以及封闭矩形条件下的压力动态 ,在数值反演计算中同时考虑表皮系数和井筒存储对压力动态的影响 ,了解水平井压力动态 ,对于指导水平井的生产和油藏动态分析都具有重要的指导意义。该方法还可以用于裂缝性油藏和压裂井的不稳态压力分析更多还原

【Abstract】 A mathematical model is presented to evaluate pressure response of a horizontal well in bounded homogeneous reservoirs which based on the method of point source function and research about various boundaries condition of horizontal wells.The model also used to understand the pressure behavior of a horizontal well in an infinite acting,one,two of three sealing faults and closed rectangular.Furthermore we introduce skin and wellbore storage in the numerical solution.Use of the technique is illustrated with the case of a horizontal well in a naturally fractured reservoir and fractured well.更多还原
