Description
Technical field
The utility model is the flusher of petroleum industry water injection well ground filling pipe, particularly oil field ground water injection pipe
Road pulse flushing device, for the flushing of water injection well ground filling pipe, developing result is improved, improves water filling quality.
Background technology
Due to the tube wall of water filling main line and ground flow attachment crude oil, iron rust, impurity and bacterial product, the ground of water injection well
For filling pipe after long-term use, qualified water forms secondary pollution after piping, has had a strong impact on water filling quality, has caused
The contamination and plugging on stratum, water injection rate decline until stratum does not absorb water.The purging method of oil field individual well filling pipe at present, mainly has
It is several below：Increase filling pipe flow first, utilizing, the flush pipe in a manner of the water after big yield flushing pipe enters tank car
Road.This method is limited by tank car capacity, and flushing discharge capacity is smaller, it is difficult to which the impurity of tube wall attachment, sludge are washed away, imitates
Fruit is poor, and the pressure of flood pattern is reduced using this method flushing pipe, have impact on the water filling work of other wells.Two
It is that the mode of pickling carries out the cleaning of water injection well pipeline.The acid washing method cost is higher, and easily produces a large amount of stink damps
Body, execute-in-place potential safety hazard are big；If if the control of acid adding dosage is bad to easily cause pipe perforation.Third, utilize high-pressure water shot
The method that stream and special dirty cleaning tool carry out physics cleaning to pipeline, this method use the party mainly for the hard scale in pipeline
Method is cleared up, need to pipeline tapping, the operating time is long, it is big and costly to injure to caused by pipeline, about 100,000 yuan/Km, very
Hardly possible is in oil field large-scale application.
The content of the invention
The purpose of this utility model is to provide oil field ground filling pipe pulse flushing device, using gas pulses technology,
The developing result of ground filling pipe is improved, the dirt in filling pipe is removed, improves injection water quality, improve water filling quality.
Technical solution of the present utility model is：Oil field ground filling pipe pulse flushing device includes tank car, air
Compressor is connected with gas storage bag and magnetic valve by gas pipeline, and pulse signal generator is connected by signal cable with magnetic valve,
The outlet of gas pipeline is connected with water filling flow, well head and the tank car in distributing room for water injection successively.
Compared with prior art, significantly using effect of the present utility model is：The utility model make use of gas pulses to send out
Raw technology, the air in air compressor is entered in gas storage bag buffered first, magnetic valve is connected with pulse signal generator, made
Magnetic valve is opened and closed with fixed frequency, and magnetic valve is opened every time all discharges a certain amount of gas, forms the gas of fixed frequency
Body slug enters in the ground water filling pass tubes of water injection well, while opens the upper valve of water filling flow and dirty valve, with
The higher gas pulses pressure of less discharge matching, high-speed pulse water flow is formed, to water filling flow and well head pipe wall
In impurity, the attachment such as dirt carry out the agitation of strength and wash away, make to be attached to impurity on tube wall, sludge, oxide, thin
The attachments such as bacterium product, soft dirt are thoroughly washed away.Through field experiment, by cleaning front and rear contrast and sight to surface duct
Examine, it was demonstrated that the clearance rate of soft attachment is more than 95% in pipeline.Chemically examined by tracking sampling, water filling flow middle pipe road leading portion
It is basically identical with the water quality of pipe end after flushing.The developing result of water injection well ground pipeline is significantly improved, is effectively improved
Injection water quality.Manufacturing cost of the present utility model is low, easy to operate, and developing result is notable, significantly reduces production cost, tool
There are significant economic benefit and using effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
