摘要

根据达西渗流理论及势的叠加原理推导出反七点井网内压力梯度计算方法。利用此计算方法可计算出不同注采压差条件下反七点井网内各点压力梯度大小、存在启动压力梯度油田注水开发时可动区域范围以及不同注采压差下的极限注采井距，可为反七点井网调整井的部署提供理论依据。

Abstract

Based on the classical Darcy equation and potential superposition principle，the pressure gradient on the invert 7-spot area well pattern was deduced.According to this method， the pressure gradient of each point on invert 7-spot area well pattern can be calculated.We can also use this method to calculate the ultimate injection-production well spacing when the start-up pressure gradient has to be taken into account.This method provides a theoretical basis for the future well injection allocation.

Key words： Potential; Threshold pressure gradient; Dead oil point; Invert 7-spot area well pattern
