Description

Technical Field

[0001] The utility model relates to the technical field of oil exploitation, in particular to a continuous shocker while drilling. Background Art

[0002] During the drilling operation, due to complex geological structures (such as wellbore collapse, plastic flow and extrusion of formations in open holes) and improper technical measures (such as too long pump stop time, bit balling, etc.), drill string sticking often occurs, and the shocker is one of the effective tools to relieve sticking accidents.

[0003] For many different types of sticking, since the shocker has developed to date, there have been many successful sticking release cases. However, for complex well conditions, conventional shockers are difficult to achieve the expected effect and have the following deficiencies:

[0004] 1. For sand plugging and gravel sticking during the completion process, due to the continuous accumulation of sand and gravel, the conventional shocker can only generate a single one-way shock after being pulled or pressed, and a long time is required for resetting and preparation work when shocking again, so it is difficult to achieve the purpose of releasing sticking.

[0005] 2. For coiled tubing sticking, due to multiple up and down movements of the conventional shocker during the sticking release process, the coiled tubing fails due to fatigue, resulting in great economic losses. Content of the Utility Model

The hose is communicated with the hollow block, and the end of the hose penetrates through the trough body. A water pump is arranged in the trough body, and the water pump is communicated with the hose.

[0010] As a further description of the above technical solution: A first sliding groove is horizontally formed on the top surface of the top plate. A first sliding block is slidably connected in the first sliding groove. The first sliding block is fixed on the top surface of the guiding block. A threaded hole is horizontally penetrated through the side surface of the guiding block. A screw rod is threadedly connected in the threaded hole. One end of the screw rod is rotatably connected to a side plate. The side plate is fixed on the bottom surface of the top plate, and the other end is drivingly connected to a driving motor.
