A hydraulic pulse vibration device

Abstract

This utility model belongs to the field of oil reservoir vibration unblocking technology, and more specifically relates to a hydraulic pulse vibration device for oil reservoir unblocking. It includes an injection cylinder, a reversing injection component, and a hydraulic adjustment component. The injection cylinder has an injection chamber and a water passage chamber along its axial direction. A water injection hole is provided on the side wall of the injection chamber, connecting the side wall of the injection cylinder and the injection chamber to inject water through vibration. The hydraulic adjustment component is located on the water passage chamber near the outlet end, and can adjust the water flow rate at the outlet end of the water passage chamber. By separately opening the injection chamber and the water passage chamber in the injection cylinder, high-pressure water passes through the water passage chamber before entering the injection chamber for pulse vibration injection. The adjustment device can pass through the water passage chamber to adjust the hydraulic adjustment component, eliminating the need to remove the entire hydraulic pulse vibration device from the oil well for adjustment.
