Abstract
The utility model discloses a pneumatic control device for a chuck of an oil bushing, which comprises a control box, a lower chuck control cylinder and an upper chuck control cylinder. A control panel of the control box is provided with two pneumatic control valves and two pressure gauges. Working ports A of the two pneumatic control valves are respectively connected with closed ports of the upper and lower chuck control cylinders. Working ports B of the two pneumatic control valves are respectively connected with open ports of the upper and lower chuck control cylinders by pilot remote control valves. The working ports B of the two pneumatic control valves are also respectively connected with pneumatic remote control ports of the opposite pilot remote control valves. The pneumatic control device for the chuck of the oil bushing does not need an upper chuck operator so as to reduce labor and avoid the high-altitude operation. A drill stand operator can be far away from a well mouth and can operate at the safe position, and thus, the operation safety and the operation efficiency can be improved.
Description
Technical field
The utility model relates to a kind of oilfield drilling control device, particularly a kind of tubing and casing chuck air control unit.
Background technology
Casing job is important link in the oil gas well drilling operation process, present marine casing job mainly adopts upper and lower scroll chuck to hold the operating type that sleeve pipe carries out shackle on the screw thread, operation format is that a people carries out upper chuck folding operation on the sleeve pipe stabbing board and sleeve pipe is set upright operation, three people carry out casing tong operation and lower chuck folding operation etc. at well head, because this operating type relates to work high above the ground, potential safety hazard is bigger, labor strength is big, inefficiency, and need two people to control respectively, cooperate and to cause the sleeve pipe well that falls when bad.
Be to reduce labor strength, the lot of domestic and international manufacturer production air operated slips, promptly utilize cylinder to drive the slips body and move, replace the operation of workman's muscle power.For preventing maloperation, the on-the-spot joystick that still needs manually to move cylinder is operated, and the advantage of doing like this is more directly perceived, meets Field Force's custom, shortcoming is dangerous, still may occur the sleeve pipe well situation that falls when bad when the upper and lower scroll chuck operating personnel cooperate.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of safe and reliable tubing and casing chuck air control unit.
A kind of tubing and casing chuck air control unit of the present utility model comprises: control cabinet and lower chuck control cylinder and upper chuck control cylinder, the control panel of control cabinet are provided with two pneumatic control valves and two pressure meters; The working hole A of two pneumatic control valves remains silent with the pass of upper and lower scroll chuck control cylinder respectively and is connected, the working hole B of two pneumatic control valves mouthful is connected by opening of guide's remote-controlled valve and upper and lower scroll chuck control cylinder respectively, and the working hole B of described two pneumatic control valves also is connected with the pneumatic remote-control mouth of guide's remote-controlled valve of the other side respectively.
Preferably, the piston rod of described upper and lower scroll chuck control cylinder is connected with the joystick of upper and lower scroll chuck control valve respectively.
The utility model can be cancelled the upper chuck operating personnel, reduces manpower, avoids high-altitude application; The rig floor operating personnel can to relatively safer position operation, therefore can improve operational security and operating efficiency away from well head.
Description of drawings
Fig. 1 is the schematic diagram of tubing and casing chuck air control unit.
The specific embodiment
Below in conjunction with Figure of description the utility model is further described.
As shown in Figure 1, the utility model comprises: control cabinet 9 and lower chuck control cylinder 5, upper chuck control cylinder 7, the control panel of control cabinet 9 are provided with 1,2 and two pressure meters of two pneumatic control valves; Remain silent and 72 are connected in the working hole A of pneumatic control valve 1 and the pass of lower chuck control cylinder 7, the working hole B of pneumatic control valve 1 mouthfuls 71 is connected by opening of guide's remote-controlled valve 8 and lower chuck control cylinder 7; Remain silent and 52 are connected in the working hole A of pneumatic control valve 2 and the pass of upper chuck control cylinder 5, the working hole B of pneumatic control valve 2 mouthfuls 51 is connected by opening of guide's remote-controlled valve 3 and lower chuck control cylinder 5; The working hole B of pneumatic control valve 1,2 also is connected with the remote control mouth of guide's remote-controlled valve 3,8 of the other side respectively.
When the utility model used, control cabinet 9 was placed on the rig floor position of safety relatively and broad view, even can be placed on the driller and operate in the room.Connecting pneumatic pipeline from control cabinet 9 is connected with lower chuck control cylinder 7, lower chuck control valve 6, upper chuck control cylinder 5, upper chuck control valve 4 respectively.The piston rod of cylinder 7 and cylinder 5 is connected with the joystick of valve 6 with valve 4 respectively.
During operation, if pneumatic control valve 1,2 is all got to off-position, air pressure remains silent 72,52 through the A of 2 control valves working hole to the pass of lower chuck control cylinder 7, upper chuck control cylinder 5, promote the upper and lower scroll chuck handle, make upper and lower chuck cylinder 5,7 be in closed condition, upper and lower scroll chuck can tighten tubing and casing.If being put into the position, casing seat need open one of them chuck, as upper chuck, operation pneumatic control valve 2 is to opening the position, air pressure is through the working hole B of pneumatic control valve 2, the guide's remote-controlled valve 3 unlatching mouth 51 to upper chuck control cylinder 5, by the handle of upper chuck control cylinder 5 pulling upper chuck control valves 4, open upper chuck; This moment, pneumatic control valve 1 was in off-position, and the working hole B of pneumatic control valve 1 does not have pressure, and guide's remote-controlled valve 3 is in unimpeded state under the spring force effect, and guide's remote-controlled valve 8 is in off-state under gas pressure, make lower chuck control cylinder 7 be in closed condition; Even and maloperation this moment is in out the position with pneumatic control valve 1, air pressure makes guide's remote-controlled valve 3 and 8 all be in off-state, and upper chuck control cylinder 5 and 7 akinesias of lower chuck control cylinder avoid upper and lower scroll chuck all to be in open mode, causes the sleeve pipe well that falls.
Because the utility model can be cancelled the upper chuck operating personnel, reduce manpower, avoid high-altitude application; The rig floor operating personnel can to relatively safer position operation, therefore can improve operational security and operating efficiency away from well head.
