The invention relates to an adjusting device of a non-well-killing operation machine.The adjusting device comprises two parallel stretching and contracting device guide outer sleeves and stretching and contracting device guide inner sleeves located in the stretching and contracting device guide outer sleeves, a cross bar is connected between the two stretching and contracting device guide outer sleeves, the cross bar is provided with a front-rear adjusting hydraulic cylinder, the outer ends of the stretching and contracting device guide inner sleeves are provided with upper body and lower body connection lug seats, the outer sides of the two upper body and lower body connection lug seats are connected with a connection rod, and a stretching and contracting rod of the front-rear adjusting hydraulic cylinder is connected to the connection rod; the front-rear adjusting hydraulic cylinder stretches out and draws back to drive the upper body and lower body connection lug seats to move back and forth, so that a whole operation platform, a derrick, blowout preventer stacks and the like are driven to move front and back.According to the adjusting device, the well repair function, operation under pressure and a well fluid reinjection process are organically combined, the non-well-killing operation machine which is high in efficiency is formed, in the work and transfer processes of the operation machine, consignment and hoisting equipment is not needed, manpower, materials and financial resources are greatly saved, and the adjusting device is convenient, rapid and novel.
Description
technical field [0001] The invention belongs to the technical field of downhole operation devices for oil and gas wells, and in particular relates to an adjustment device for a snubbing machine. Background technique [0002] When oil wells, water injection wells or gas wells are used for downhole operations, when there is pressure in the wells, it is usually necessary to perform well killing or blowout depressurization treatment first. Because well killing is easy to pollute the formation, blowout will reduce local formation pressure and cause ground pollution. Therefore, the operational measures of no snubbing and no blowout have been paid more and more attention to and popularized by various oilfields. [0003] In the case of pressure in the well, in order to realize workover operations without snubbing and blowout, it is necessary to have a complete set of snubbing operation device, which can effectively combine the snubbing operation device with workover rigs and other ...
