                Abstract:
                In the development of unconventional oil and gas reservoirs, perforation is first used as a leading process for fracturing, followed by a channel for oil and gas in subsequent production. In this paper, a new type of perforating charge with a variable wall thickness liner is developed, which has high flow efficiency and is suitable for fracturing of unconventional oil and gas reservoirs. Numerical simulation shows that the jet head formed by the new perforating charge has higher initial velocity and more stable shape. The flow efficiency of simulated formation conditions and field application tests show that the new perforation charge has a higher flow efficiency and a smaller friction than the deep penetration charge, which makes the new perforating charge have advantages in the development of unconventional oil and gas reservoirs.
