Abstract
The invention discloses a device for throwing a dissolving agent into a rubber barrel of a restrictor, which is designed for realizing smooth fishing of the restrictor. The steel wire is connected to the connector upper end of this device, and the barrel is connected to the lower extreme to it is sealed by the axial sealing washer. The upper part of the cylinder wall is provided with an injection screw hole which is connected with a screw cap and sealed by a sealing rubber ring. The inner wall step of the bottom end of the cylinder body is connected with a bottom cover, and the bottom cover is fixed by a pin penetrating in the step and in the radial direction and is sealed by a sealing ring. The barrel is internally provided with a spring, 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 device can be in close contact with the throttler, the rubber cylinder can be efficiently dissolved, the waste of a dissolving agent can be avoided, and the fishing efficiency and the success rate are improved. The device has the advantages of simple structure, convenient construction, safety and environmental protection.
Description
Technical field
The present invention relates to a kind of reducer packing element lytic agent delivery device, belongs to natural gas well production technique field.
Background technology
In gas exploitation course, for blood pressure lowering, throttling and limited production, underground throttle device is generally thrown in the wellbore, revived
It is slip-type underground throttle that Sulige gas field is wide variety of.Underground throttle device is delivered to the pre-determined bit of pit shaft by steel wire operation
Put, fixed by the slips on reducer and oil pipe, the annular space of tube inner wall and reducer is sealed by packing element.Sometimes, root
Reducer to be salvaged according to the demand of production, to adjust gas well mouth gas production.But when salvaging at the scene, the glue of partial throttling device
Cylinder cannot bounce back, so that the borehole wall and packing element frictional force are excessive, break salvaging steel wire, make salvaging fail.
The content of the invention
It is an object of the invention to provide a kind of reducer packing element lytic agent delivery device, to realize smoothly beating for reducer
Drag for.
The particular technique content of the present invention is as follows：
The union joint upper end connection steel wire of this device, lower end connector drum, and sealed by axial sealing ring.On cylinder barrel
Injection silk hole being provided with coupling nut, being sealed by O-ring seal.Cylinder bottom inwall step connection bottom, bottom is by being through platform
Pin in rank, radial direction is fixed, and is sealed by sealing ring.Spring is provided with cylinder, spring upper end connects union joint bottom surface, under
End connection bottom.
This device and reducer close contact, can efficiently dissolve packing element, it is to avoid the waste of lytic agent, improve and salvage effect
Rate and success rate.This apparatus structure is simple, easy construction, safety and environmental protection.
Description of the drawings
Fig. 1 is reducer packing element lytic agent delivery device structural representation.
Specific embodiment
Embodiment：
Embodiments of the invention are further illustrated with reference to Fig. 1：
This device includes main union joint 1, axial sealing ring 2, O-ring seal 3, nut 4, spring 5, cylinder 6, sealing ring
7th, pin 8 and bottom 9；
1 upper end of union joint connects steel wire, lower end external screw thread connector drum 6, and is sealed by axial sealing ring 2.6 barrel of cylinder
Injection silk hole being provided with coupling nut 4, being sealed by O-ring seal 3,6 bottom inwall step connection bottom 9 of cylinder, bottom 9
Fixed by pin in step, radial direction 8 is through, and sealed by sealing ring 7.Spring 5, the connection of 5 upper end of spring are provided with cylinder 6
1 bottom surface of union joint, lower end connection bottom 9.
The course of work of this device is as follows：
Assembling：The upper end of spring 5 is fixed on into 1 bottom surface of union joint, lower end connects bottom 9, and now, 5 stress of spring is in
Extended state.Sealing ring 7 is installed on 6 bottom inwall step of cylinder, and with 8 connector drum 6 of pin and bottom 9.From cylinder 6
Appropriate packing element lytic agent is injected in injection silk hole on wall into cylinder, then installs O-ring seal 3, tightening nuts 4.
Throw in：This device is thrown in by steel wire operation, and in decentralization process, spring 5 is in extended state all the time.When decentralization extremely
After the certain position of reducer top, jarring delivery tool cuts off pin 8, makes spring 5 bounce back, and opens bottom 9, makes pre- in cylinder 6
The packing element lytic agent put flows to reducer packing element.After several minutes, this device is proposed, carry out conventional reducer fishing.
