Description
Technical field
The utility model relates to a kind of oil gas water well mouth apparatus for work more particularly to a kind of production tree four-way counterbalance valve to load and unload
Tool.
Background technique
Oil gas water well mouth device sleeve valve flange, steel ring thorn leakage at present, scene generally uses and robs dress or well killing change
Processing mode.And scene robs dress generally use is common counterbalance valve handler, scene without successful application case, because
This, mostly uses greatly the mode of well killing change.And both the above mode is to the slight thorn leak of live outside of sleeve valve and steel ring
, there is unworthiness in reason.
The counterbalance valve handler of present common application（The counterbalance valve handling produced such as Jiangsu petroleum machinery Co., Ltd
Device）There are the problem of it is as follows：
1, it is had the following problems in application at the scene：Quality weight, scene need crane coordinating operation, increase operation at
This, also increases Work places security risk.Cumbersome, structure is complicated, and installing and dismounting is hydraulic drive, operating time mistake
Long, the single operation time at least needs 45min, and working efficiency is not high.Easy to damage, which is more than 2m, always
The problems such as length is more than 3.6m, and assembly deformed damaged is easily caused in transport, use process, and seal member thorn leaks.
2, conventional Well Killing replacement is long there are the kill-job time, it is big to damage to production pay, and oil gas water well recovery time is long, to well
It can lead to the drawbacks such as thorn leakage expansion when aculea leakage issue handling fond of food that is not salty.
The exploitation of many years is passed through in domestic some oil fields now（As system in Tahe Oilfield passes through exploitation in 20 years）, reservoir formation energy
Amount gradually declines, and for 90% or more oil gas water well, normal well head pressure is no more than 10MPa, and is more than 64% oil gas water well
Well head pressure is less than 1 MPa.Therefore, it for the leakage of steel ring and flange, thorn leakage issue handling on the outside of wellhead casing pipe gate, develops
Tool that is light-duty, facilitating operation carries out installing and dismounting counterbalance valve, is the task of top priority convenient for the maintenance and replacement of wellhead assembly.
Summary of the invention
The utility model provides the oil recovery that a kind of production of adaptation oil field needs for the above-mentioned problems of the prior art
Set four-way counterbalance valve handling instrument, overcome quality present in counterbalance valve handling instrument is overweight, structure is complicated, it is cumbersome,
Problem easy to damage.
Technical solutions of the utility model are as follows：
A kind of production tree four-way counterbalance valve handling instrument, it is characterised in that it is by pushing ram, screw thread propulsion tube, pressure-bearing
Cylinder, counterbalance valve and five part of pressure release cock composition, pushing ram connect with screw thread propulsion tube by buttress thread, screw thread propulsion tube and
Pressure-bearing cylinder is mounted by screwed connection, counterbalance valve and pushing ram by pin, and high pressure relief cock is by screwed connection in pressure-bearing
On cylinder.
The counterbalance valve and pushing ram mounts, and pressure-bearing cylinder is threadedly attached in production tree four-way outer valves flange outdoors
On screw thread, pushing ram is rotated by spanner, pushing ram and the cooperation of screw thread propulsion tube generate forward thrust, and pushing ram promotes counterbalance valve
To production tree four-way, counterbalance valve is mounted on production tree by the pressure release cock pressure release installed on pressure-bearing cylinder by borehole pressure
It is realized inside four-way and production tree four-way side is blocked.
The beneficial effects of the utility model are as follows：
1, light-weight, 2-3 people can operate, and cooperate without half crane, use cost and security risk is effectively reduced；
2, simple and strong for structure durable, frequently low using failure rate, maintenance and repair is at low cost；
3, easy to operate, can be by skilled operation after intermediate skill operation personnel simple knowledge operating principle, it can be to greatest extent
The field operation time is reduced, live well head out-of-control time is shortened.
The important technological parameters contrast table of the utility model and conventional tool is as follows：
| Conventional tool | The utility model tool | |
| Installation number | Installation needs 4 people | Installation needs 2 people |
| Labor intensity | It is high | It is low |
| Environmental pollution | A large amount of consumption hydraulic oil | Nothing |
| Equipment attrition | Seriously | It is few |
| Use cost | Half crane is needed to cooperate | Nothing |
| Operation difficulty | It is complicated（Need professional training） | Simply |
By the comparison of two kinds of counterbalance valve handling instruments, use can be effectively reduced in the utility model tool in use
Cost, cooperates without half crane, and two people can be completed the installation and dismantlement work of counterbalance valve, have while reducing use cost
Effect improves the safety of operation process.And environmental pollution, operation difficulty, in terms of obtained effectively changing
It is kind, it has broad popularization and application prospect.
