Description
Technical Field

[0002] Oil and natural gas are buried in oil and gas layers tens of meters to thousands of meters underground. To extract it, it is necessary to establish an oil and gas channel between the ground and the underground oil and gas layer. This channel is the well. A workover rig is often used in well repair work. A workover rig is a mechanical equipment specially used for well repair work. It is usually composed of a car chassis and special well repair mechanical equipment. It is a commonly used downhole operation equipment in oil field exploration and development, and plays a very important role in downhole operations. The main function of the workover rig is to remove or repair problems such as well wall collapse and sediments. It cannot change the patency of the well, but it can help remove sediments and formation impurities at the bottom of the borehole to ensure the permeability of the borehole. The working principle of the workover rig is to complete the well repair operation through the rotation and push of the downhole equipment. The rotation of the downhole power head can provide rotational force to tools such as workover tongs for processing pipes and equipment in the well, while the push of the downhole power head can provide driving force to tools such as workover hammers for processing solid materials in the well.
