Description
Technical field
The invention belongs to the water injection well Acidizing Technology field in water flooding field underground work engineering, it is related to one kind
For the acid filling sled used in the online acidizing treatment of low-permeability oil deposit.
Background technology
The poor low-permeability oil deposit of oil field at home particularly physical property at present, after waterflooding extraction certain time, it is most of all
The problem of water injection capacity declines occurs, this is mainly due to caused by the near wellbore zone pollution in the injecting process.Often now
Water injection well stimulation measure is acidifying de-plugging, and conventional acidulation is present that long construction period, labor intensity are big, working procedure is complicated
The defects of, the online Acidizing Technology of water injection well fixed tubular column is invented for this country, technology development at present is more rapid, construction
Well number and workload rise year by year.
But acid filling equipment used in online acidizing treatment is mostly that huge discharge, the acid filling infusion of high flow rate enter acid solution, in hole
When degree and permeability low-permeability oil deposit construction less than normal, have that the operation pressure rate of climb is too fast, and operation pressure is too high, therefore go out
The problems such as now security risk is too high.And when constructing, equipment dynamic source comes from the big electricity in well site, electricity consumption examination ＆ approval, professional attaching be present
The problems such as, construction period is extended, reduces efficiency of construction.
The content of the invention
The shortcomings that it is an object of the invention to overcome above-mentioned prior art, there is provided it is sour online that one kind is used for low-permeability oil deposit
Change construction acid filling sled used, acid filling sled can security risk it is relatively low, and acidizing treatment efficiency high, and operation pressure can
Control.
To reach above-mentioned purpose, the acid filling sled of the present invention for used in the online acidizing treatment of low-permeability oil deposit includes
Generator, voltage-stabilized power supply device, driving motor, acid filling pump, acid storage tank and switch board；
The output end of generator is connected through voltage-stabilized power supply device with the power interface of driving motor, the output shaft of driving motor
It is connected with the drive shaft of acid filling pump, the entrance of acid filling pump is connected with the outlet of acid storage tank, the outlet of acid filling pump and water injection well
Well head is connected, and switch board is connected with the control terminal of voltage-stabilized power supply device and the control terminal of acid filling pump.
The outlet of acid filling pump is connected with wellhead of water injection well by high-pressure acid-resistant pipeline.
The high-pressure outlet of acid filling pump is connected with wellhead of water injection well.
Generator is explosion-proof type 35KW diesel-driven generators.
Acid filling pump is acidproof three-cylinder plunger pump.
The nominal diameter of high-pressure acid-resistant pipeline is DN50.
The invention has the advantages that：
Acid filling of the present invention for used in the online acidizing treatment of low-permeability oil deposit is prized in concrete operations, generator
The electricity sent is that driving motor is powered after carrying out voltage stabilizing by voltage-stabilized power supply device, and driving motor drives acid filling pump work, acid filling pump
Drive the acid in acid storage tank to enter in water filling well shaft, realize that water injection well fixed tubular column is acidified online.It should be noted that this
Invention is that acid filling pump is powered by generator and voltage-stabilized power supply device, the construction for avoiding tradition from being brought using external electrical network power supply
The problem of cycle length, low construction efficiency, so as to effectively improve the efficiency of construction of acidifying；Furthermore it is possible to adjusted by switch board
The running parameter of voltage-stabilized power supply device and acid filling pump, the safety wind for avoiding the too fast or operation pressure of operation pressure growth excessive and bringing
Dangerous problem.
