Abstract
The utility model discloses a sealed rubber cylinder fishing tool for a slip-type underground throttle, which is designed for solving the problem that the sealed rubber cylinder of the throttle is difficult to fish. A conical body with a movable lug is connected with the lower end of a body of the sealed rubber cylinder fishing tool; when the movable lug is retracted inward, the conical body can extend into the sealed rubber cylinder of the underground throttle; and after the movable plug is opened, the external diameter of the conical body is more than the internal diameter of the sealed rubber cylinder of the underground throttle, so that the sealed rubber cylinder of the underground throttle can be lifted out from a well by using the finishing tool. The sealed rubber cylinder fishing tool provided by the utility model has the advantages of reasonable design, simple structure, convenience in operation and high practical applicability and effectiveness.
Description
Technical field
The utility model relates to a kind of slip-type underground throttle device cartridge fishing tool, belongs to the oil and gas exploitation field of engineering technology.
Background technology
In natural gas extraction; For throttling, step-down, limited production; Underground throttle device usually is installed in the gas well down-hole; The underground throttle device of present Su Lige gas field extensive use is the slip-type underground throttle device, produces replacing restriction choke valve because production needs gas well to transfer, and will salvage restriction choke when perhaps losing efficacy owing to restriction choke.During salvaging, restriction choke because cartridge is excessive with the frictional force of the borehole wall, causes cartridge to break away from restriction choke and quilt is left in pit shaft in pit shaft when up easily, causes follow-up underground work to carry out.
Summary of the invention
The purpose of the utility model is to provide a kind of slip-type underground throttle device cartridge fishing tool, is a kind of with piano wire operation and cartridge fishing tool simple in structure.
The concrete technology contents of the utility model is following:
Slip-type underground throttle device cartridge fishing tool is made up of joint, body, movable ear, pin, cone, body upper end jointing, and the lower end connects cone, and cone is provided with groove, and movable ear is connected in the groove by pin.
During the containing withdrawal of movable ear, cone can stretch in the underground throttle device cartridge, strut movable ear after, its external diameter is greater than underground throttle device cartridge internal diameter, causes the underground throttle device cartridge can be with proposing well on the fishing tool.The utility model is reasonable in design, and is simple in structure, easy to operate, practicability and effectiveness.
Description of drawings
Accompanying drawing is a slip-type underground throttle device cartridge fishing tool structural representation.
The specific embodiment
Embodiment:
Embodiment to the utility model further specifies with reference to accompanying drawing:
At body 2 upper end thread connecting joints 1, the lower end cone 5 that is threaded; On cone 5, offer groove, movable ear 3 is connected in the groove, and movable ear 3 can be realized 0～90 ° of rotation around pin 4 with pin 4.
The utility model is accomplished the salvaging process of slip-type underground throttle device cartridge through steel wire operation.
Connect the fishing tool string before the use, instrument is in proper order from top to bottom: rope socket+weighted lever+bumper jar+slip-type underground throttle device cartridge fishing tool.
At first confirm cartridge position in pit shaft, during operation, slowly transfer the cartridge fishing tool being positioned at the above 2-3m of cartridge place, push away under the cartridge at fishing tool under the inertia force effect avoiding; When cone 5 and movable ear 3 passed cartridge, movable ear 3 can be drawn close to body 2 around pin 4 by the cartridge barrier effect, causes cone 5 to pass cartridge smoothly; When movable ear 3 does not receive external force, under the effect of self gravitation, outwards open, with 2 one-tenth 90 angles of body °; Make its external diameter greater than the cartridge internal diameter; Carry tool string on this moment, cartridge then goes out well with tool string is up, salvages the success of underground throttle device cartridge.
