摘要
对已有的联合井网（五点法注采井网）的产能公式进行了深入研究，运用等值渗流阻力法重新推导出五点井网的产量计算公式，根据镜像反映和势的叠加原理给出该井网的三维求解过程，并运用以上方法进行了实例求解。结果表明，新推导出的公式比原有公式的计算精度高。
Combination production of vertical and horizontal wells of 5spot
pattern is studied. A new formula for calculating production rate is introduced by using the flow
resistance method. Based on the imaging and the superposition principles, a 3D steady state
solution of the pattern is proposed. An example of production rate was calculated by the new
formula. The method suggested in this paper can improve the accuracy of calculation, and it can
forecast productivity in the oilfield development program for using a combination of horizontal
and vertical wells.
