Description
Technical field
The utility model relates to oilfield, specifically a kind of self-circulation well flushing truck.
Background technology
The self-circulation well flushing truck in current oil field, generally adopt Swirling flow sand-removing, swash plate oil removing, walnut shell filter technology to water injection well counter go out sewage process, eventually pass ram pump and be recycled in water injection well.But still there is a large drawback, namely water technology is too complicated, too long in flow, and equipment is overweight, flushing fluid water conditioning is unstable, operation and maintenance inconvenience.Above-mentioned treatment unit mainly relies on the processing power of strainer, but also there are two large limitation in strainer itself, one is that filter plant needs regular back flushing, back flushing frequency is limited by the condition of water quality of well-flushing water, back flushing produces a large amount of sewage needs discharger, therefore, the frequency of back flushing and effect may make device normally run.Two is due to device intermittent operation, and filtrate is easy to breed bacteria, often causes filter plant normally to run.As time goes on, cause the flow of well-flushing too small, well-flushing does not reach ideal effect.
Summary of the invention
In order to overcome the deficiency that existing self-circulation well flushing truck needs regular back flushing, well washing effect bad, the utility model provides a kind of self-circulation well flushing truck, this self-circulation well flushing truck can realize the not outer row of sewage in washing well process, improve sewage treatment capacity, and well washing effect is good.
The technical solution of the utility model is: a kind of self-circulation well flushing truck, the water-and-oil separator comprised described in water-and-oil separator is divided into left and right two portions by dividing plate, and dividing plate top has the groove about the connection of horizontal direction, it is settling bowl on the left of dividing plate, right side is oil-water separation tank, two portions are separated into by several risers in described oil-water separation tank, wherein left upper portion is provided with contaminated-oil basin, it is lambdoid column plate that the bottom of contaminated-oil basin is fixed with several, and oil-water separation tank right upper portion is equipped with oil-scraping device; The right-hand member of described water-and-oil separator is fixed with chemicals dosing plant, chemicals dosing plant has respectively sterilant entrance and the flocculation agent inlet of the oil-water separation tank led to.
Top board in described settling bowl and base plate are fixed with several baffle plates respectively, and have between the baffle plate on top and base plate between gap, the baffle plate of bottom and top board and have gap.
The utility model has following beneficial effect: owing to taking such scheme, adds sterilant and flocculation agent, realize the sterilization to sewage and flocculation by sterilant entrance and flocculation agent inlet.Floating superincumbent sump oil can be scraped into contaminated-oil basin by oil-scraping device; and by multistage column plate 4 process after and settling bowl 2 carry out level 2 buffering sedimentation, the local water after process is injected into well by sleeve pipe again, thus realizes continuous circulation environmental protection well-flushing; the not outer row of flushing fluid, protects environment.And the sewage treatment capacity of this self-circulation well flushing truck is high, can saving water resource, reduce oil well production cost, improve crude oil recovery rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-water-and-oil separator in figure, 2-settling bowl, 3-contaminated-oil basin, 4-column plate, 5-oil-scraping device, 6-sterilant entrance, 7-flocculation agent inlet, 8-chemicals dosing plant, 9-well counter go out sewage mouth, 10-oil-water separation tank, 11-sand removing hole, 12-dividing plate, 13-baffle plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of self-circulation well flushing truck, comprise water-and-oil separator 1, described water-and-oil separator 1 is divided into left and right two portions by dividing plate 12, and dividing plate 12 top has the groove about the connection of horizontal direction, left and right two portions are communicated with by groove, and be settling bowl 2 on the left of dividing plate 12, right side is oil-water separation tank 10.Top board in described settling bowl 2 and base plate are fixed with several baffle plates 13 respectively, have between the baffle plate 13 on top and base plate between gap, the baffle plate 13 of bottom and top board and have gap, and the baffle plate of the baffle plate on top and bottom is alternately arranged, can flow velocity be slowed down like this, make throw out and remaining silt particle be deposited to bottom.Described oil-water separation tank 10 inside is separated into left and right two portions by several risers, and gap is arranged at the top of riser or bottom, and left and right two portions are communicated.On the left of riser, inside is fixed with several is lambdoid column plate 4, and column plate about 4 is arranged, forms multistage column plate, can slow down the speed that bottom sewage floats.Contaminated-oil basin 3 is fixed with, for depositing sump oil above column plate 4.Oil-water separation tank 10 right upper portion is equipped with oil-scraping device 5, and the greasy dirt of sewage surface in oil-water separation tank 10 falls in contaminated-oil basin 3 after scraping off by oil-scraping device 5.The right-hand member of described water-and-oil separator 1 is fixed with chemicals dosing plant 8, chemicals dosing plant 8 has respectively sterilant entrance 6 and the flocculation agent inlet 7 of the oil-water separation tank 10 led to, and water-and-oil separator 1 right-hand member top be connected with well counter go out sewage mouth 9.
During well-flushing construction, oil reservoir return the sewage that spues through inlet well counter go out sewage mouth 9 enter water-and-oil separator 1, chemicals dosing plant 8 starts simultaneously, carries out drop dosing, add sterilant and flocculation agent respectively by sterilant entrance 6 and flocculation agent entrance 7, realize the sterilization to sewage and flocculation.Under the dual function of medicament with gravity, realization oil, water are separated with silt particle preliminary sedimentation, and the sump oil swum on the water surface is scraped into contaminated-oil basin 3 by recycling oil-scraping device 5, use underflow pump to be entered slop oil tank simultaneously; Residual mixed liquor body after multistage column plate 4 processes, then enters settling bowl 2 and carries out level 2 buffering sedimentation, realizes the sedimentation of small throw out and remaining silt particle; local water after process is injected into well by sleeve pipe again; thus realizing continuous circulation environmental protection well-flushing, the not outer row of flushing fluid, preserves the ecological environment.And the sewage treatment capacity of this self-circulation well flushing truck is high, can saving water resource, reduce oil well production cost, improve crude oil recovery rate.
