Abstract
The utility model relates to a forcing compression type underground throttle salvaging tool for salvaging a movable underground throttle in the process of gas field development, which comprises a connector, a controller, a stroke spring, a limit cylinder, a pop-up rod, a shrink cylinder and a salvaging grab, wherein the connector can be in screwed connection with other tools; the controller is fixed on the connector by shear pins; the stroke spring is jammed by the controller and is pressed by the pop-up rod; the limit cylinder limits the stroke spring and the pop-up rod; the pop-up rod is connected with the controller by a jamming block; the shrink cylinder forms a cylinder structure with a shrink track for the salvaging grab; all components are arranged in the shrink cylinder; the salvaging grab forms a grab spring structure, comprises three grabs and is embedded in a track slot of the shrink cylinder; and a forcing compression mechanism comprises the controller, the stroke spring and the pop-up rod. The forcing compression type underground choke salvaging tool solves the problem of difficult or failed salvage in prior art caused by that a rubber cylinder is always in a sealing state in the process of being lifted upside because the rubber cylinder completing expansion sealing cannot be effectively and completely unsealed. The salvaging tool can be widely used for salvaging the movable underground throttle in the process of gas field development.
Description
Technical field:
The utility model relates to the enforce compression formula underground throttle device fishing tool of movable underground throttle device salvaging usefulness in a kind of gas field development process.
Background technology:
The movable underground throttle device fishing tool of existing conventional, carrying out restriction choke when salvaging, be passive salvaging, to the packing element of finishing Expansion sealing deblocking effectively fully, on carry that packing element is in the state of setting all the time in the process, cause fishing difficulty or failure.
The utility model content:
The purpose of this utility model provides a kind of enforce compression formula underground throttle device fishing tool, it is passive salvaging that this instrument has solved what exist in the prior art, to the packing element of finishing Expansion sealing deblocking effectively fully, on carry that packing element is in the state of setting all the time in the process, cause the problem of fishing difficulty or failure.
The technical scheme that its technical problem that solves the utility model adopts is: enforce compression formula underground throttle device fishing tool, by connector, controller, the stroke spring, position-limiting drum, ejection rod, shrink cylinder, bailer grab is formed: connector can with other instrument screwed connection, controller is a kind of fixture block limiting structure, original state is fixed in connector by shear pin, the stroke spring, have enough springing stroke, block by controller, ejection rod compresses it, position-limiting drum carries out spacing to stroke spring and ejection rod, ejection rod is connected with the controller fixture block, eject the restriction choke central tube that the back compression is salvaged, shrink cylinder is that band drags for the cylindrical structure that pawl shrinks track, and all components all is loaded on and constitutes fishing tool integral body in it; Bailer grab is the pawl spring structure, is made up of three pawls, is embedded in the rail groove of shrink cylinder; Enforce compression mechanism is made up of controller, stroke spring, ejection rod.When using this fishing tool, enforce compression formula underground throttle device fishing tool is lowered in the pit shaft to the underground throttle device position of preparing to salvage, by action of gravity, bailer grab is caught the slips mechanism of underground throttle device, bailer grab together enters shrink cylinder together with the slips mechanism of the underground throttle device that is booked, on when carrying connector shear pin cut off, controller will discharge ejection rod, stroke length of spring compressed ejection rod ejects it simultaneously, the central tube return of compression underground throttle device, the slips of underground throttle device and cartridge will be forced to deblocking simultaneously.The pick-up drag Lock-out realizes salvaging smoothly.
The beneficial effects of the utility model are that this tool construction is simple, and are easy to use, fishing success ratio height, construction safety, reliable; This instrument is in guaranteeing underground throttle device salvaging process, and slips and cartridge are forced to deblocking simultaneously, can guarantee that fishing carries out smoothly.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure 1, connector, 2, controller, 3, the stroke spring, 4, position-limiting drum, 5, spring lever, 6, shrink cylinder, 7, bailer grab.
The specific embodiment:
In the accompanying drawings, enforce compression formula underground throttle device fishing tool, by connector 1, controller 2, stroke spring 3, position-limiting drum 4, ejection rod 5, shrink cylinder 6, bailer grab 7 is formed: connector 1 can with other instrument screwed connection, controller 2 is a kind of fixture block limiting structures, controller 2 is fixed with connector 1 usefulness shear pin, stroke spring 3 is blocked by controller 2, ejection rod 5 is with its compression, 4 pairs of stroke springs 3 of position-limiting drum and ejection rod 5 carry out spacing, and ejection rod 5 is connected with controller 2 fixture blocks, and shrink cylinder 6 is that band drags for the cylindrical structure that pawl shrinks track, all components all is loaded in it, bailer grab 7 is the pawl spring structure, is made up of three pawls, is embedded in the rail groove of shrink cylinder 6; Enforce compression mechanism is made up of controller 2, stroke spring 3, ejection rod 5.
