Problems solved by technology

At present, the oil-water well pressure devices used in the field have a simple structure, and the parts in the sealing system are severely worn, which increases the operating cost and is difficult to meet the needs of complex operating processes
In addition, the auxiliary supporting devices of the existing pressurized operation devices are relatively simple, so there are hidden dangers in safety

Description

Technical field: [0001] The invention relates to a complete set of equipment for downhole workover of oil and water wells in oil fields. Background technique: [0002] With the extension of oilfield development process and oil-water well production time, oil-water well maintenance operations are becoming more and more frequent, and the number of wells under pressure is increasing. At present, the oil-water well pressure devices used in the field have a simple structure, and the parts in the sealing system are severely worn, which increases the operating cost and is difficult to meet the needs of complex operating processes. In addition, the auxiliary supporting devices of the existing pressurized operation device are relatively simple, so there are hidden dangers in safety. Invention content: [0003] The object of the present invention is to provide a pressure-operating device for oil-water wells with good sealing performance, safe and reliable operation, and meeting the...
