A pumping bridge plug hydraulic setting power tool

Abstract

This utility model discloses a hydraulic setting power tool for pump-driven bridge plugs, relating to the field of oilfield downhole tool technology, and solves the problems of existing hydraulic bridge plug setting tools being non-reusable, having low pulling force, and low efficiency. In this utility model, the inlet connector, cylinder liner structure, and pusher are connected sequentially, with the piston structure located inside the cylinder liner structure. The upper end of the piston structure is connected to the inlet connector, and the lower end is connected to the puller head; the puller head is located inside the pusher head. Flow channels are provided inside the inlet connector and the piston structure, and several piston cavities are provided between the piston structure and the cylinder liner structure. The flow channels and piston cavities are connected. Well fluid enters the cavities, pushing the piston structure upwards, and the pusher head squeezes the bridge plug, causing it to expand laterally and be set and released onto the casing wall. This utility model effectively improves the setting pulling force by connecting multiple hydraulic cylinders in series to form a whole and working synchronously; at the same time, it can be repeatedly used in the field for downhole operations, achieving safe and reliable bridge plug setting and release operations.
