| 摘 要： | 依据压裂水平井不同流动区域的流动规律, 将压裂水平井的渗流分为裂缝中的高速非达西流
动区、裂缝控制影响的椭圆渗流区、远离裂缝的基质非达西渗流区, 考虑启动压力梯度的影
响, 对压裂水平井两相渗流进行了分析, 得到了低渗透油层压裂水平井的产量公式. 研究结
果表明, 裂缝的导流能力越大, 压裂水平井的产量越高. 但随着开采时间的增加, 其产量递减幅度越
大; 压裂裂缝长度越小, 压裂水平井的初始产量越高. 但随着生产时间的推移, 压裂裂缝的
长度越大, 产量的递减幅度越小; 中间裂缝长, 两翼裂缝短的情况下, 压裂水平井的产量最
高.

| Abstract: | According to flow characteristics of different flow areas of fractured horizontal wells in low permeability oil reservoirs,the vadose region of fractured horizontal wells can be divided into three districts,the non-Darcy flow district with a high speed controlled by cracks,the ellipse flow district and the matrix non-Darcy flow district.Two-phase porous flow mathematical models of matrix non-Darcy flow with start-up pressure gradient are built.The results indicate that the production goes with the increase ... |
