摘要: 利用数值模拟方法对五点法、七点法、九点法注水方式不同见水时刻水平井与垂直井联合井网的波及系数进行的研究结果表明,油水流度比、水平井穿透比及水平井与水平方向的夹角对3种联合井网波及系数的影响较大.在对各种影响因素分析对比的基础上,得出了各影响因素与波及系数的关系曲线,并对数值模拟结果进行了回归,得到了联合井网的波及系数与各影响因素之间的定量关系.

Abstract: The sweep efficiency of horizontal-vertical combined well patterns at water-breakthrough time with five-spot,seven-spot and nine-spot water-injection methods was simulated numerically.The result shows that mobility ratio of oil to water,penetrating ratio of horizontal well and included angle between horizontal well and horizontal axis have great influences on sweep efficiency of three combined well patterns.On the basis of analysis and contrast of the influencing factors,the curves of influencing factors related to sweep efficiency were drawn.The simulation results were regressed,and the quantitative relations between sweep efficiency and its influencing factors were gained.

Key words: waterflood development, sweep efficiency, horizontal well, vertical well, combined pattern, numerical simulation
