Abstract
The utility model discloses a flow regulator rubber sleeve dissolution agent putting device. The flow regulator rubber sleeve dissolution agent putting device is designed for achieving the purpose that a flow regulator can be smoothly fished. According to the flow regulator rubber sleeve dissolution agent putting device, the upper end of a connector is connected with a steel wire, the lower end of the connector and a sleeve body are connected, and are sealed through an axial sealing ring, and an injection threaded hole is formed in the upper portion of the sleeve wall of the sleeve body, is connected with a nut, and is sealed through a rubber sealing ring; a step on the portion, arranged at the bottom end of the inner wall of the sleeve body is connected with a bottom cover, and the bottom cover is fixed through a radial dowel which penetrates through the step, and is sealed through a sealing ring; a spring is arranged in the sleeve body, the upper end of the spring is connected with the bottom surface of the connector, and the lower end of the spring is connected with the bottom cover. The flow regulator rubber sleeve dissolution agent putting device can make close contact with the flow regulator, a rubber sleeve can be dissolved efficiently, waste of dissolution agents can be avoided, fishing efficiency is improved, and the success rate is increased. The flow regulator rubber sleeve dissolution agent putting device is simple in structure, convenient to construct, safe and friendly to the environment.
Description
Technical field
The utility model relates to a kind of restriction choke packing element lytic agent delivery device, belongs to natural gas well production technique field.
Background technology
In gas exploitation course, for step-down, throttling and limited production, conventionally in pit shaft, throw in underground throttle device, what revive Sulige gas field extensive use is slip-type underground throttle.Underground throttle device, by steel wire operation, is delivered to the precalculated position of pit shaft, by the slips on restriction choke and oil pipe, is fixed, and relies on the annular space of packing element Seal Oil inside pipe wall and restriction choke.Sometimes, according to the demand of producing, to salvage restriction choke, to adjust gas well mouth gas production.But while salvaging at the scene, the packing element of partial throttling device cannot bounce back, thus the borehole wall and packing element frictional force excessive, break salvaging steel wire, make to salvage unsuccessfully.
Summary of the invention
The purpose of this utility model is to provide a kind of restriction choke packing element lytic agent delivery device, to realize the smooth salvaging of restriction choke.
Concrete technology contents of the present utility model is as follows:
The connector upper end of this device connects steel wire, and lower end connects cylindrical shell, and is sealed by axial sealing ring.Cylindrical shell barrel is provided with injection silk coupling nut, that sealed by O-ring seal hole.Cylindrical shell bottom inwall step connects bottom, and bottom is fixed by being through pin in step, radially, and is sealed by sealing ring.In cylindrical shell, be provided with spring, spring upper end connects connector bottom surface, and lower end connects bottom.
This device and restriction choke close contact, can dissolve packing element efficiently, avoids the waste of lytic agent, improves and salvage efficiency and success rate.This apparatus structure is simple, easy construction, safety and environmental protection.
Accompanying drawing explanation
Fig. 1 is restriction choke packing element lytic agent delivery device structural representation.
The specific embodiment
Embodiment:
With reference to Fig. 1, embodiment of the present utility model is further illustrated:
This device comprises main connector 1, axial sealing ring 2, O-ring seal 3, nut 4, spring 5, cylindrical shell 6, sealing ring 7, pin 8 and bottom 9;
The course of work of this device is as follows:
Assembling: the upper end of spring 5 is fixed on to connector 1 bottom surface, and lower end connects bottom 9, and now, spring 5 is stressed in extended state.On cylindrical shell 6 bottom inwall steps, sealing ring 7 is installed, and is connected cylindrical shell 6 and bottom 9 with pin 8.Appropriate packing element lytic agent is injected in injection silk hole from cylindrical shell 6 barrels in cylinder, then O-ring seal 3 is installed, tightening nuts 4.
Throw in: this device is thrown in by steel wire operation, and in decentralization process, spring 5 is all the time in extended state.When transferring to the certain position of restriction choke top, jarring delivery tool, cuts off pin 8, makes spring 5 retractions, opens bottom 9, makes the interior preset packing element lytic agent of cylindrical shell 6 flow to restriction choke packing element.After several minutes, propose this device, carry out conventional restriction choke fishing.
Claims (1)
