This invention provides a sand-proof, non-magnetic hydraulic oscillator, relating to the technical field of hydraulic oscillators. The sand-proof, non-magnetic hydraulic oscillator includes an upper connector, one end of which is fitted with the oscillator body. A rotating impeller drives a rotating connecting shaft, which in turn drives a conveying auger. The conveying auger, in turn, drives a rotating scraper. The rotating scraper agitates the sand adhering to the surface of the sand-blocking filter, preventing a large amount of sand from accumulating on the filter surface. After agitating the sand into the liquid medium, the conveying auger's spiral pushing direction—from the sand-blocking filter towards the rotating impeller—causes the liquid medium containing a large amount of sand to move away from the filter, increasing the sand's fluidity and effectively preventing clogging of the filter. This then drives the motor, preventing the accumulation of sand and gravel impurities in the medium between the rotor and stator after drilling stops, thus solving the problems of difficulty in restarting and jamming during construction.

This invention relates to the field of drilling equipment technology, specifically a high-pressure pulse jet coupled anti-torque loading and unloading sub, comprising a long joint, a short joint, a slide, an inner tube, a frame, a movable ring, an anti-torque coupling assembly, an inlet ring, an outlet ring, an annular drive chamber, an oil inlet hole, an oil outlet hole, an oil inlet passage, an oil outlet passage, and a cylindrical groove. The anti-torque coupling assembly is disposed within the cylindrical groove. During the process of injecting hydraulic fluid into the annular drive chamber through the oil inlet hole and oil inlet passage, the hydraulic fluid pushes the movable ring to move, causing the anti-torque coupling assembly to open within the cylindrical groove. This allows the output end of the anti-torque coupling assembly to extend from within the frame and abut against the inner wall of the cylindrical groove, applying torque to the inner tube and preventing axial displacement. This invention is specifically designed for effectively controlling anti-torque in high-pressure pulse operations, enhancing operational stability, improving operational efficiency, and extending tool life.

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.
