针对油气勘探与开发过程中断层对油藏试井分析影响以及边界元方法在油气渗流和试井分析中应用研究的问题，通过建立考虑井附近有断层情形非均质油藏数学模型，应用边界元方法建立积分方程、矩阵方程最终求取井底压力，进而对压力和压力导数的双对数分析后，最终确定井附近存在断层及不渗透区时应首先综合利用地震资料对井附近断层进行识别，再决定利用某种试井模型对试井曲线进行解释。
針對油氣勘探與開髮過程中斷層對油藏試井分析影響以及邊界元方法在油氣滲流和試井分析中應用研究的問題，通過建立攷慮井附近有斷層情形非均質油藏數學模型，應用邊界元方法建立積分方程、矩陣方程最終求取井底壓力，進而對壓力和壓力導數的雙對數分析後，最終確定井附近存在斷層及不滲透區時應首先綜閤利用地震資料對井附近斷層進行識彆，再決定利用某種試井模型對試井麯線進行解釋。

The problems of faults having difficulties in well testing analysis and applied research of boundary element method on oil and gas seepage and well test analysis exist in the procese of exploration and develapment of oil and gas. Through establishing homogeneous reservoir mathematic model of faults near wells and by adopting boundary element method, integral equation and ma?trix equation are established, and then bottom hole pressure(BHP) is obtained and double log of pressure and pressure derivative is analyzed. Finally, it is concluded that, when faults and impermeable areas occur near wells, the comprehensive utilization of seis?mic data is needed to identify them. And afterwards, using which well test model to explain well test curves can be decided.
