Description
Technical field
The utility model belongs to sewage treatment plant, particularly relates to a kind of oilfield sewage treatment device with desanding piston.
Background technology
Water injection well in oil fields well-flushing, owing to being subject to the impact of the factor such as oil field environment-protection, water quality, is never well solved.The appearance of Swirling flow sand-removing technology for washing well has solved this problem well.Its technical process is as follows: well-flushing water → water injection well between water filling → anti-flushing well flow process → down-hole well-flushing → well tubing counter go out → through continuous hose → one-level hydrocyclone → secondary hydrocyclone → through connecting hose → production wellhead → return station pipeline → test satellite location.This closed process one is the source problem that comes that has solved well-flushing water, the 2nd, solve the whereabouts problem of backflow sewage, and water injection well in oil fields well-flushing problem is resolved substantially.But, this process unit but by anti-well-flushing go out all kinds of impurity stayed in the hydrocyclone of well washing apparatus.Present solution is to be discharged by the header under hydrocyclone, arbitrarily abandons, and the residual sewage in hose is arbitrarily discharge also, and in addition, due to the existence of residuary water, winter, easy freezing, cannot normally use, and had caused environmental pollution.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of oilfield sewage treatment device with desanding piston is provided.
Oilfield sewage treatment device with desanding piston of the present utility model, to be formed by backwashing sewage water pipeline, one-level hydrocyclone, the secondary hydrocyclone of water injection well, backwashing sewage water pipeline is connected with one-level hydrocyclone pipeline, one-level hydrocyclone is connected with secondary hydrocyclone pipeline, and the export pipeline of secondary hydrocyclone is connected on the outer defeated gathering pipeline of oil well.Wherein, the equal pipeline of bottom blow-down mouth of one-level hydrocyclone and secondary hydrocyclone is connected to sand filter, and described sand filter is to have connected end socket by filtration main body to form.
As further improvement of the utility model, in filtration main body, there is desanding piston, there is filtration seben in filtration main body and end socket junction, the export pipeline of high-pressure gas cylinder is connected with backwashing sewage water pipeline and filtration main body pipeline respectively.
As further improvement of the utility model, end socket is connected with export pipeline pipeline.
As further improvement of the utility model, the filtration main body of sand filter is provided with purging valve, safety valve and dosing mouth.
As further improvement of the utility model, on each connecting pipeline, be equipped with switch-valve.
Oilfield sewage treatment device with desanding piston of the present utility model, apparatus structure is reasonable in design, the solid in impurity thoroughly can be separated with liquid, and desanding effect is good, environment friendly and pollution-free.
Brief description of the drawings
Fig. 1 is the structural representation of the oilfield sewage treatment device with desanding piston of the present utility model.
Embodiment
Oilfield sewage treatment device with desanding piston of the present utility model, to be formed by backwashing sewage water pipeline 1, one-level hydrocyclone 2, the secondary hydrocyclone 3 of water injection well 17, backwashing sewage water pipeline 1 is connected with one-level hydrocyclone 2 pipelines, one-level hydrocyclone 2 is connected with secondary hydrocyclone 3 pipelines, and the export pipeline 11 of secondary hydrocyclone 3 is connected on the outer defeated gathering pipeline 4 of oil well 18.One-level hydrocyclone 2 is connected to sand filter 5 with the equal pipeline of bottom blow-down mouth of secondary hydrocyclone 3, and described sand filter 5 is to have connected end socket 7 by filtration main body 6 to form.Be connected by pipeline 19 with export pipeline 11 at end socket 7.
In filtration main body 6, have desanding piston 8, have in filtration main body 6 and end socket 7 junctions the seben 9 of filtration, the export pipeline of high-pressure gas cylinder 10 is connected with backwashing sewage water pipeline 1 and filtration main body 6 pipelines respectively; The import of high-pressure gas cylinder 10 has connected air compressor 15, its top has connected safety valve I 16, can be by the residual water that sky purges in bomb 10.
The filtration main body 6 of sand filter 5 is provided with purging valve 12, safety valve 13 and dosing mouth 14.The operating pressure 16MPa that filters main body 6, will ensure operating pressure, ensures again both ends open safety, and desanding piston can either move under gas pressure, ensures again its trafficability characteristic, filters seben and can filter, have again suitable intensity.
Oilfield sewage treatment device with desanding piston of the present utility model, is equipped with switch-valve on its each connecting pipeline.
Oilfield sewage treatment device with desanding piston of the present utility model, add desanding piston at sand filter 5, add filtration seben at the end of desanding main body, promote to filter impurity in main body 6 to filtering seben 9 by desanding piston, oil-water mixture in impurity is leached by the road and 19 is entered producing well gathering pipeline by filtration seben 9, and the solids such as impurity are under the extruding of desanding piston and the effect of chemical agent, become solid shape caking, take out via the seal head end of screwed connection again, bring back oil recovery factory's incinerator and burn.Thereby make the residual full scale clearance of sewage, impurity, the discharge producing without dirt.
