Abstract

The present application discloses a method and device for controlling perforation plugging operations. The method comprises: acquiring the pre-plugging fracturing fluid displacement and the target diversion pressure for a perforated interval; invoking a plugging ball quantity model to calculate the target number of plugging balls; computing the theoretical diversion pressure based on the post-plugging displacement and ball quantity; adjusting the post-plugging displacement when the theoretical pressure does not exceed the target pressure until it does; performing the plugging operation using the determined ball quantity and adjusted displacement; determining whether the plugging is effective by comparing the bottomhole pressure difference before and after the operation with the target diversion pressure. This method enables accurate determination of the number of plugging balls and fluid displacement after plugging, thereby ensuring that the fracturing operation meets the designed requirements.
