利用数值模拟方法对五点法水平井与垂直井联合井网不同见水时刻的波及系数进行了研究。研究表明:油水流度比、水平井穿透比及水平井与水平方向的夹角对五点法联合井网波及系数的影响较大。在对各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。
The numerical simulation method was used to study the wave propagation coefficients of five-point horizontal well and vertical well in combination with well pattern at different water seepage times. The results show that the oil-water flow ratio, horizontal well penetration ratio and horizontal angle between horizontal well and horizontal well have a great influence on the well coefficient of five-point well pattern. Based on the analysis and comparison of various influencing factors, the relationship curves between influencing factors and wave coefficients were obtained, and the numerical results were regressed. The quantitative relationship between the wave coefficients and the influencing factors was obtained .
