Description
Technical field
This utility model is related to the medicine machine of petroleum industry water injection well, particularly a kind of water injection well chemicals dosing plant, is note
The dosing cleaning special purpose device of well ground well head inwall and down-hole string, sleeve pipe and oil reservoir, is also applied for dosing.
Background technology
At present, it is for example following to the cleaning way and defect of the down-hole string and underground equipment of water injection well：
First, it is currently to process injection well pipe column and underground equipment with acid solution.The equipment such as cementing truck, sour tank, sour pond need to be used, into
This height, workload are big, dangerous, are not suitable for periodically sour cleaning treatment.The disposable residual acid residue yield for processing is big, note
Water easily blocks oil pipe, injection well downhole flow regulator, not only affects water filling quality, and also wants more costly down-hole after blocking oil pipe and injection well downhole flow regulator
Operating cost.
2nd, beating acid solution mainly uses cementing truck at present.Relatively near between water injection well and oil well in well group, some well groups discharge water
Head, but because of safety and quality problem, it is basic to disable.The annual freight costliness produced for acid treatment, up to millions of units not
Deng.And wait the time of vehicle long, cause profit landing pollution.If allow produce after well-flushing in well group containing residual sour, residual
The flushing fluid of slag is transported to block station, then distance is remote, and treating capacity and difficulty increase.
3rd, stop sand, mud, dirt, polymer and other debris in note well casing post to be deposited in the tail pipe of tubing string bottom, in pocket
Mud, reservoir sand, polymer etc. bury stifled tail pipe, under the conditions of tubing string does not leak, cause positive injection note not intake.Way is inspection pipe at present
Sand washing is visited, it is logical to scrape well-flushing cylinder.
4th, as mud, fouling, the projection for tying rust are tied in water injection well tube wall, test is hampered, and current solution is to drill through
Well, well-flushing, inspection pipe etc..
5th, as the long-term injecting water in oil field is developed, water injection well near wellbore zone is easy to contamination and plugging, and stratum is because injection water
The impact of matter and fouling, cause water injection capacity constantly to decline, and injectivity index diminishes.Settling mode main at present is that well is washed
Well, operation inspection pipe or pickling unblocking and injection increasing, and single conventional well washing effect is poor, operation inspection pipe or acid are implemented in upper operation routine
Wash unblocking and injection increasing cost again higher.
6th, on wellhead of water injection well ball-and-seat, valve, four-way, " U " type pipe, standpipe fouling are serious, and crushing is big, serious shadow
Water-injection efficiency is rung.
The content of the invention
For the problem that above-mentioned water injection well is present, there is provided a kind of water injection well chemicals dosing plant, using the height of water injection well distributing room for water injection
Pressure water completes pickling operation, reduces the vehicle transport expense of acid treatment, reduces production cost, reduces environmental pollution, ensures water filling
The normal water filling of well.
The technical solution of the utility model is：A kind of water injection well chemicals dosing plant includes jet pump, medicinal liquor barrel and high-pressure hose,
Articulation is installed in the pipeline at high-pressure hose two ends, the articulation of one end is connected with the import of jet pump, the loose joint of the other end
Head is connected with the water injection valve from distributing room for water injection, and medicinal liquor barrel is connected by plastic lined piping with the negative pressure suction inlet of jet pump, jet pump
Outlet with test valve be connected.
Compared with prior art, remarkable result of the present utility model is：This device is former using the work of jet pump venturi
Reason, applied hydrodynamics conservation of energy principle, i.e. unit fluid potential energy, pressure energy and kinetic energy sum are constant.Nozzle in jet pump,
When water under high pressure is dammed by nozzle, flow rate of water flow greatly improves i.e. kinetic energy to be increased, then the pressure that fluid has will also be greatly reduced
Even negative pressure；Because caliber increases after flowing through nozzle, flow velocity is reduced, then fluid pressure can rise again.This device is arranged on well
Mouthful, in the negative pressure suction inlet suction acid solution of jet pump, after being mixed into mixed liquor stream with water under high pressure in the negative pressure room of jet pump
Into the well head and down-hole string of water injection well, the purpose of cycle pickling cleaning treatment tubing string is reached.This device is applied to water injection well
Pickling and the dosing such as anti-corrosion work, institute's adding medicine includes Compound-acid, formaldehyde, preservative, scale remover etc..High pressure can be made during pickling
Water passes through nozzle and negative pressure chamber, and acid solution is connected with negative pressure chamber, water under high pressure pass through after mixing with acid solution jet pump shout manage and
Diffusing opening can just realize that acid solution and the mixing of water under high pressure are accompanied, and in oil pipe or sleeve pipe, reach cleaning tubing and injection well downhole flow regulator
Purpose.The water injection well distributing room for water injection high-pressure sewage of itself is make use of, without cementing truck, tank car, fiberglass pond, just can implement acid
Wash.
In to the daily management of water injection well, each block water filling can be determined according to the fouling result of laboratory test of water filling well shaft
The acid-solubility of well, then further preferably goes out the later stage because formation blockage causes the well shorted, carries out pickling maintenance, improves its water filling and imitates
Really.By to water injection well implement routine pickling, successfully solve because formation blockage, pit shaft fouling and it is caused short problem,
The interval qualification rate of well group is improved, and is to improve water flooding level to lay a good foundation.
This device is used in combination jet pump and medicinal liquor barrel has just reached pickling and dosing using the high-pressure sewage in distributing room for water injection
Purpose, significantly reduces production cost, protects environment, improves work efficiency, with significant economic benefit and society's effect
Benefit.
