Description
Technical field
The present invention relates to natural gas fields, in particular to liquid-adding device.
Background technique
With the continuous intensification of natural gas well recovery percent, the natural gas well can gradually generate hydrops phenomenon.When gas well energy
When comparing sufficient, hydrops can drain into together in the gas transmission line of ground with air-flow；And when gas well energy is lower, hydrops will be
Fluid column is formed in well, is gently then greatly lowered the gas production of gas well, it is heavy then gas well is caused to be crushed to death halt production.
In order to exclude hydrops in well, field engineering technical staff and professional science and technology staff development have gone out a variety of water pumping gas production works
Process.Scene is commonly mainly gas lift method, plunger method and bubble row's method at present.And in above-mentioned three kinds of water drainage-gas recovery technology methods
In, it is most widely used to count foam drainage gas recovery process, that is, above-mentioned described bubble row's method.Bubble row's method is exactly that will add
Work is added in the natural gas well for having hydrops at rodlike either liquid foaming agent, mixes with the hydrops in well, reduces product
The surface tension of liquid forms the very low aerated fluid of density, as the air-flow of rising is arranged together under the stirring action of natural gas
To ground, achieve the purpose that water pumping gas production.
Liquid foam discharging agent charging method is usually filled using on-board high-voltage pump.On-board high-voltage pump charging method be exactly
Foaming agent fluid reservoir and a high-pressure pump by diesel engine as power are installed on one tank car.Foam discharging agent is filled in well
When, bubble row's vehicle is parked in the place remote away from the tens of rice of well head, high pressure line is connected on the special joint of well head christmas tree, is then opened
Diesel engine and high pressure injectant pump is opened to inject foaming agent in gas well oil jacket annulus.Termination of pumping when injection rate reaches design requirement, then tear open
High pressure line is unloaded, other a well is then gone to repeat identical operation.Using this operation mode, the foaming agent of a well is completed
Filling about needs 40-50 minutes time.
During realizing that on-board high-voltage pump filling foaming agent is filled, inventor has found that the prior art at least exists
Following problems:
(1) large labor intensity of site operation personnel, required operator is more, and filling foam discharging agent requires vehicle-mounted every time
Loading system reaches well site, connection high pressure line, filling foaming agent, disassembly pipeline, and every trolley needs to configure three operators；
(2) equipment investment fund is high, and every trolley carries loading system can be only done the workload of 5-6 mouthfuls of wells daily, if there is
Tens mouthfuls of wells need to carry out bubble row, it is necessary to configure more than ten set filing provisions, increase equipment investment amount and operator, cause
Dosing increased costs；
(3) equipment damage rate is high, and since the foaming agent of addition generallys use aqueous medium dilution, this undoubtedly increases high pressure and adds
The abrasion of pump is infused, in addition, the frequent disassembly of the dedicated fill adapter of well head also substantially reduces its service life, leads to the dimension of equipment
Repair increased costs.
(4) bubble row low efficiency causes foam discharging agent to be concentrated and reaches underground, failing since the discharge capacity of high pressure dispenser pump is larger
Well head is discharged together in the well-mixed situation of hydrops in well just with air-flow, causes the waste of foaming agent, reduces draining
Efficiency.

Pressure relief ball valve 70) latus rectum be 25mm.This example is only a kind of illustrated examples, is not construed as to one kind of the invention
Limitation.
Fluid injection ball valve 30, liquid feeding ball valve 40, equilibrium ball valve 60 and pressure relief ball valve 70 can according to the requirement of automatic liquid-feeding and
Sequence completes balance, fluid injection, pressure release and the liquid adding functions of gas well.And it is only used in the whole process by solar panel power supply
In the control of four electrical ball valves, while liquid-adding device also uses liquid in multiple liquid storage cylinders 10 during whole service
Gravitation energy foaming agent is injected into well, without using injection pump, thus more energy efficient, safer.
The tool of liquid-adding device 100 is further illustrated below by working principle and process that liquid-adding device 100 is described in detail
Body structure.
By liquid-adding device 100 it is prefabricated at the scene on the basis of after the installation is completed, successively open pressure relief ball valve 70 (the purpose is to
By the air discharge in liquid feeding in the process cellular high pressure liquid storage cylinder 10), by the foaming agent for needing to fill with injectant pump by adding
Liquid ball valve 40 is added in multiple liquid storage cylinders 10；Pressure relief ball valve 70 and liquid feeding ball valve 40 are closed after filling it up with foaming agent, while will note
Liquid ball valve 30 and equilibrium ball valve 60 are connected on the annular space connector of christmas tree with high-pressure hose；Christmas tree annular space valve is opened later
Door opens the high-pressure natural gas that equilibrium ball valve 60 introduces in well, makes pressure and gas well oil jacket annulus in multiple liquid storage cylinders 10
Pressure balances each other；After the pressure balance of the two, i.e., openable fluid injection ball valve 30.Foaming agent in multiple liquid storage cylinders 10 is at itself
It is injected in oil jacket annulus under the action of gravity.
When the foaming agent quantity of addition reaches design requirement, automatic control system 51 may turn off fluid injection ball valve 30, complete
At the filling of foaming agent.Automatic control system 51 starts timing, when reaching next dosing period, automatic control system 51 at this time
30 fluid injection of fluid injection ball valve can be reopened, fluid injection ball valve 30 is automatically closed after filling.And so on, until by multiple liquid storages
Until foaming agent in cylinder 10 is all added in well.
It after 3-4 dosing period, needs that foaming agent is filled it up with multiple liquid storage cylinders 10 again, add in liquid storage cylinder 10
When medicine, equilibrium ball valve 60 is closed by the control key on 51 panel of automatic control system first, the pressure of oil jacket annulus is cut
It is disconnected；Then pressure relief ball valve 70 is opened, the pressure in multiple liquid storage cylinders 10 is released；Liquid-feeding tube is connected to liquid feeding ball valve later
On 40, foaming agent is added in multiple liquid storage cylinders 10.After liquid storage cylinder 10 is filled it up with, pressure relief ball valve 70 and liquid feeding ball valve are successively closed
40, equilibrium ball valve 60 is opened later, can be entered next dosing and be recycled.
