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 that has been this domestic utility model, 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.
Utility model content
The shortcomings that the purpose of this utility model is to overcome above-mentioned prior art, there is provided one kind is used for low-permeability oil and ensconced
Acid filling sled used in line acidizing treatment, acid filling sled can security risk it is relatively low, and acidizing treatment efficiency high, and pressure of constructing
Power is controllable.
To reach above-mentioned purpose, the acid filling sled described in the utility model for used in the online acidizing treatment of low-permeability oil deposit
Including 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 utility model has the advantages that：
Acid filling described in the utility model for used in the online acidizing treatment of low-permeability oil deposit is prized in concrete operations, hair
The electricity that motor is 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, note
Sour pump drives the acid in acid storage tank to enter in water filling well shaft, realizes that water injection well fixed tubular column is acidified online.Need what is illustrated
It is that the utility model is that acid filling pump is powered by generator and voltage-stabilized power supply device, avoids tradition from being powered using external electrical network
The problem of long construction period that brings, low construction efficiency, so as to effectively improve the efficiency of construction of acidifying；Furthermore it is possible to pass through
Switch board adjusts the running parameter of voltage-stabilized power supply device and acid filling pump, avoids the too fast or operation pressure of operation pressure growth excessive and band
The security risk problem come.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 it is switch board, 2 be voltage-stabilized power supply device, 3 be driving motor, 4 be acid storage tank, 5 be acid filling pump, 6 is generating
Machine.
