This article mainly applies the injection-production balance board, combining the dynamic experience of oilfield development to optimize the adjustment method of injection and production parameters in fault area. Based on the law of material balance, considering the pressure limit of the fault plane and the dynamic data of development wells on both sides of the fault, by drawing the pressure balance chart of the injection and production system, the equilibrium formation pressure on both sides of the fault can be calculated. The adjustment direction is given based on the current injection and production status, so as to establish the injection and production parameter adjustment method in the study area.
