AI Technical Summary
Existing technologies for fracturing horizontal wells in shale oil reservoirs suffer from problems such as difficulty in controlling fracture initiation direction, uniform fracture morphology, insufficient fracturing volume, and fragmented operational procedures.
A directional perforation-pulsation fracturing co-control device is adopted. The directional perforation component performs directional perforation in the circumferential direction of the wellbore, and the pulse generator applies pressure pulses with adjustable frequency and amplitude during the fracturing process to form a complex fracture network.
It enables precise control of the fracture initiation direction, increases the stimulation volume and diversion capacity, improves the productivity and development efficiency of horizontal wells in shale oil reservoirs, and reduces construction time and wellbore risks.
