Pressure operating device for high pressure oil, gas and water well

It relates to a working device under pressure for oil, gas, and water wells, especially high-pressure oil, gas, and water well workover operations. It consists of upper and lower beams 1, 12, upper and lower slips 2, 3, and left and right hydraulic cylinders. 4, 5, upper and lower ring sealers 6, 10, lifting sub-section 7, hydraulic blowout preventer 8, adjusting screw 9, wellhead four-way 11 composition. This operating device is novel in design and reliable in work. It is used with downhole tubing In conjunction with the plug, it can perform workover operations on high-pressure oil, gas, and water wells under pressure without blowing out and reducing pressure and using high-density killing hydraulic wells, avoiding damage to oil, gas and water wells, making it difficult to repair for a long time The resurrection of "dead wells" in well operations ensures good results in oilfield development.
