Abstract
An oil-water separating, sand sedimentation and washing liquid recycle pool is provided, consisting of valves, an inlet to the sand sedimentation pool, a buffer pipe, a sand sedimentation pool, a sand washing liquid treatment pool, a sand washing liquid reserving pool and sewage holes. The pool is characterized in that the sand sedimentation pool is arranged to be a conical sand washing liquid treatment pool and a sand washing liquid reserving pool, which are rectangular or oval, the sand sedimentation pool and the sand washing liquid treatment pool are connected, which are separated by an overflow plate, sitting on the sand washing liquid reserving pool, both ends of which are open; a plurality of buffer pipes with openings are arranged along the rear edge of the sand sedimentation pool, with the inlet of the sand sedimentation pool in the middle of buffer pipes. Sand exhaust valves are arranged at the conical bottom of the sand sedimentation pool. An oil discharge valve and water discharge valve are arranged at the rear side of the sand washing liquid treatment pool, with the oil discharge valve on the top, and a water discharge valve at the bottom of the rear side of the sand washing liquid treatment pool.
Description
One, technical field
The utility model relates to oil field a kind of sand cleaning fluid circulatory pool used when the workover treatment sand washing under development, specifically a kind of water-oil separating, sediment deposition sand cleaning fluid circulatory pool.
Two, background technology
At present the oil field is when sand washing, cover such as wash at construction, use original circulatory pool to make mortar in the circulation fluid, silt particle etc. can not get precipitating preferably and be pressed into well again, cause the secondary pollution on stratum and the obstruction of well tool down, serious causes well in operation unsuccessful.Underground work when using working fluid, employing be 13m
3The pond is used as depositing, circulating in the iron pond.When this method existed the circulation well killing fluid, the mortar in the well killing fluid, mortar and crude oil can not get good precipitation, floating and by in the cementing truck suction well, cause the secondary pollution on stratum, the problems such as tool jams of going into the well.
Three, summary of the invention
The purpose of this utility model provides a kind of water-oil separating, sediment deposition sand cleaning fluid circulatory pool, what solve that above-mentioned prior art exists recycles mortar, the silt particle crude oil taken out of to sand cleaning fluid and can not get preferably precipitation separation and be pressed in the well by cementing truck again, causes stratum secondary pollution problem.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of valve, setting pot inlet, separator tube, setting pot, sand cleaning fluid treatment pond, sand cleaning fluid deposit pond and mudhole, it is characterized in that setting pot is made as taper sand cleaning fluid treatment pond and sand cleaning fluid deposit pond, be set to rectangle or ellipse, setting pot and sand cleaning fluid treatment pond are made as the disjunctor pond, be separated by by overflow plate therebetween, and seat is laid on the pond sand cleaning fluid deposit pond open at both ends at sand cleaning fluid; The setting pot back end edge is along the separator tube that is provided with out several mouthfuls, the separator tube middle part is provided with the setting pot inlet, and the setting pot awl end is provided with the sediment outflow valve, is provided with oil discharging valve and Draw off valve at sand cleaning fluid treatment pond trailing flank, oil discharging valve is provided with flowing water Valve last in sand cleaning fluid deposit trailing flank bottom, pond.
Compared with the prior art the utility model has the following advantages:
1, simple in structure, reasonable in design, the sand liquid that fills that recycles is precipitated through three grades of separation, the oil that carries out in well, sand, mortar precipitation separation are gone out, sand cleaning fluid is returned with cementing truck and is carried silt particle in the well after will handling again, sand cleaning fluid recycles, and saves sand cleaning fluid and tank car.
2, the sand cleaning fluid after the processing does not cause for the second time oil reservoir and pollutes, and helps to improve the recovery ratio of oil well.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
1-sediment outflow valve 2-setting pot inlet 3-separator tube 4-setting pot 5-sand cleaning fluid treatment pond 6-oil discharging valve 7-Draw off valve 8-sand cleaning fluid standby pool 9-sewage draining exit among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
As shown in drawings, the utility model is made up of valve, setting pot inlet 2, separator tube 3, setting pot 4, sand cleaning fluid treatment pond 5, sand cleaning fluid deposit pond 8, oil discharging valve 6, Draw off valve 7 and sewage draining exit 9; Setting pot 4 is made as taper, and sand cleaning fluid treatment pond 5 and sand cleaning fluid deposit pond 8 are made as rectangle or ellipse, and setting pot and sand cleaning fluid treatment pond are made as the disjunctor pond, and its door is separated by by overflow plate, and seat is laid on the pond sand cleaning fluid deposit pond open at both ends at sand cleaning fluid; The setting pot back end edge is along the separator tube 3 that is provided with several mouthfuls of switch, the separator tube middle part is provided with setting pot inlet 2, the setting pot awl end, be provided with sediment outflow valve 1, be provided with oil discharging valve 6 and Draw off valve 7 at sand cleaning fluid treatment pond trailing flank, oil discharging valve is last, below sand cleaning fluid treatment pond side, be provided with mudhole 9, be provided with flowing water Valve 7 in sand cleaning fluid deposit trailing flank bottom, pond.
Sand cleaning fluid deposit two ends, pond are left opening and can be discharged water as water on the cementing truck and tank car, the sand cleaning fluid outlet connects setting pot inlet 2 in the well, sand cleaning fluid is by behind the separator tube 3, at first flow into setting pot 4, sand ash piece and mortar in the flushing fluid obtain sedimentation for the first time, water was expired the sand setting overflow, flow into flushing fluid treatment pond 5, flushing fluid obtains sedimentation for the second time in treatment pond, clean water is by outlet gate 7, flow into flushing fluid deposit pond 8, the sand after the setting pot sedimentation has clearance hole 1 to discharge, and mortar is discharged by sewage draining exit 9.
