Abstract
The utility model discloses a high-pressure well opening device with a pneumatic fracturing valve. The high-pressure well opening device comprises an oil pipe head device (1), a fracturing valve (2), a pneumatic valve (3), an oil-gas extraction tree (4) and an air pressure driving device (5). The fracturing valve (2) and the air pressure driving device (5) form the pneumatic fracturing valve in a conventional assembly mode; the oil pipe head device (1) and the pneumatic fracturing valve form a fracturing well opening in a conventional assembly mode; and the oil-gas extraction tree (4), the pneumatic valve (3) and the fracturing well opening form the high-pressure well opening device with the pneumatic fracturing valve in a conventional assembly mode. According to the high-pressure well opening device, manual operation is reduced by adopting a pneumatic structure, the high-pressure well opening device can be remotely controlled and is small in switch torque, device replacement is not needed between shale gas fracturing and exploiting, and the high-pressure well opening device is safe, efficient and short in working cycle.
Description
Technical field
The utility model belongs to high pressure oil wells pressure break tree wellhead assembly field, relate to and be widely used in the exploitation of shale gas high-pressure fracturing well head, to complete high pressure fracture work, thereby the shaft collar of crack and secondary fracturing in pressure break shale is specifically related to a kind of high-pressure well mouth apparatus with pneumatic fracturing valve.
Background technology
As everyone knows, the exploitation of shale gas needs high-pressure well mouth that can pressure break, and common well head is not not reach pressure break requirement at present, is exactly that well head pressure does not reach requirement, the well head that known shale gas exploitation is used is external import substantially, procurement cycle is long, price is high, difficult in maintenance, increased maintenance cost, reduced christmas efficiency, after shale gas pressure break, need to change oil and gas extraction wellhead, need to increase manually, postpone job schedule, affect whole well head christmas efficiency.
Summary of the invention
The purpose of this utility model is: a kind of high-pressure well mouth apparatus with pneumatic fracturing valve is provided, simple in structure, with low cost, easy to maintenance, can manually, surge, pneumatic between quick-replaceable, reduce moment of torsion, after shale gas pressure break, do not need again to change oil gas mining equipment, improve the effective rate of utilization of fracturing valve well head and the operating efficiency of oil and gas extraction wellhead.
Technical solution of the present utility model is: this high-pressure well mouth apparatus comprises tubing head device, fracturing valve, pneumatic operated valve, christmas tree device and actuating device of atmospheric pressure, fracturing valve and actuating device of atmospheric pressure routinely assembling mode form pneumatic fracturing valve, tubing head device and Pneumatic pressure split valve assembling mode composition fracture well head routinely, and christmas tree device, pneumatic operated valve and fracture well head routinely assembling mode form the high-pressure well mouth apparatus with pneumatic fracturing valve.
The utlity model has following advantage:
1, after shale gas pressure break, do not need again to change oil gas mining equipment, improve the effective rate of utilization of fracturing valve well head and the operating efficiency of oil and gas extraction wellhead.
2, the high-pressure well mouth apparatus with pneumatic fracturing valve adopts modular construction, and distribution as required, also can coordinate sale with other products of company, does not exist market to overstock risk, improves the performance of enterprises.
3, be a kind of wellhead assembly with high pressure fracture valve with the high-pressure well mouth apparatus of pneumatic fracturing valve, not only play common well head effect, can also carry out pressure break and make the division of oil gas crack, and the pneumatic actuating device adopting, can play and reduce fracture well head moment of torsion, replace manual operation, reach the object of Long-distance Control.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: 1 tubing head device, 2 fracturing valves, 3 pneumatic operated valves, 4 christmas tree devices, 5 actuating device of atmospheric pressure.
Detailed description of the invention
As shown in Figure 1, this high-pressure well mouth apparatus comprises tubing head device 1, fracturing valve 2, pneumatic operated valve 3, christmas tree device 4 and actuating device of atmospheric pressure 5, fracturing valve 2 and actuating device of atmospheric pressure 5 routinely assembling mode form pneumatic fracturing valve, tubing head device 1 and Pneumatic pressure split valve assembling mode composition fracture well head routinely, and christmas tree device 4, pneumatic operated valve 3 and fracture well head be the high-pressure well mouth apparatus of assembling mode entirety composition with pneumatic fracturing valve routinely.
