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
