Description
Technical field:
The utility model relates to a kind of sand, water separation device, relate in particular to a kind of carry out sand, moisture from the sand-flushing device.
Background technology:
At present, when oil well carried out the sand washing operation, the sand water that returns out entered common sand washing pond usually, post precipitation circulation sand washing; Though having taked of having comparatively advanced eddy flow desanding device, but because unreasonable structure, have a lot of disadvantages and can't realize that sand water thoroughly separates.
The sand water that returns out enters circulation sand washing pond, the sand washing though can circulate, but because the water-line of sand water out pipeline that goes out from the well internal return and pump in same pond, will make some segmentation sand reenter circulation sand washing in the well, final be difficult to the silt particle in the well thoroughly clean.
The existing pond that is equipped with hydrocyclone, can only get rid of long-pending sand under the cyclone by open and close sediment outflow gate, when the sediment outflow closing gate, can not realize eddy flow desanding function, overwhelming majority silt particle enters circulation sand washing pond, sand water can not more thoroughly be separated, silt particle still can occur and go into the situation of well circulation, sand washing operation effectiveness and efficient are reduced.
Summary of the invention:
The purpose of this utility model is to provide a kind of can improve oil well sand washing operation effectiveness and efficient greatly, and can reduce sand removal labour intensity, realize the circulation sand washing, the sand that reduces environmental pollution, moisture from the sand-flushing device.
The technical scheme that the utility model provides is: sand cleaning fluid is handled sledge, feed tube connects the inlet of eddy flow desanding device, the liquid outlet of eddy flow desanding device is being communicated with the muddy water jar by drain pipe, top one side of muddy water jar is provided with filter box, be provided with filtrate in the filter box, the opposite side of filter box is the clear water jar, and the casing of filter box is provided with sieve aperture, the sand export below of eddy flow desanding device is provided with screen pack, and the screen pack below is the muddy water jar.The eddy flow desanding device comprises an one-level hydrocyclone and two secondary hydrocyclones, the liquid outlet of one-level hydrocyclone is communicated with the inlet of two secondary hydrocyclones respectively by flow tube, the liquid outlet of secondary hydrocyclone is communicated with the muddy water jar by drain pipe, and the sand export below of one-level hydrocyclone and secondary hydrocyclone is provided with screen pack.
In addition, can be respectively equipped with a sewage draining exit and a slag notch in a side of muddy water jar and clear water jar.
Preferably screen pack is obliquely installed, the angle that makes screen pack and horizontal plane form is an acute angle.
The utility model is compared with existing eddy flow desanding pond and is had the following advantages:
1, eddy flow desanding device lower end sand export is in uncovered state all the time, guarantee the eddy flow desanding device continue to carry out sand, moisture from, help sand water and thoroughly separate; 2, the tail water that comes out from eddy flow desanding device sand export is carried out screen pack and filtrate double-filtration, good filtration effect; 3, adopt the two-stage hydrocyclone, the classification desanding, it is big to separate the sand grains diameter range, and desanding is thorough; 4, carry out circulation well cleanup with the water that washes out after the desanding, reduce the cooperation platform of water consumption and clear water tank car, save operating cost.

The specific embodiment
Introduce the technical scheme that the utility model provides in detail below in conjunction with specific embodiment.
As shown, sand cleaning fluid is handled sledge, and feed tube 1 connects the inlet of one-level hydrocyclone 2.The liquid outlet of one-level hydrocyclone 2 is communicated with the inlet of two secondary hydrocyclones 4 respectively by flow tube 3.The liquid outlet of two secondary hydrocyclones 4 is respectively by two drain pipe 6 communication channel muddy water jars 7.The sand export below of one-level hydrocyclone 2 and two secondary hydrocyclones 4 is provided with the screen pack 5 of an inclination, and screen pack 5 is an acute angle with the angle that horizontal plane forms.Screen pack 5 belows are muddy water jars 7.Top one side of muddy water jar 7 is provided with a filter box 8, and dress is holding filtrate in the filter box 8, all is sieve aperture on the casing of filter box 8.The opposite side of filter box 8 and muddy water jar 7 is clear water jars 9.
Be respectively equipped with a sewage draining exit 11 and a slag notch 10 in muddy water jar 7 one sides.
Be respectively equipped with a sewage draining exit 12 and a slag notch 13 in clear water jar 9 one sides.
During clean-out service, wash out water and enter one-level hydrocyclone 2 through feed tube 1, major diameter sand grains in the water is separated, isolated sand and low amounts of water are discharged from one-level hydrocyclone 2 bottom sand exports.Water after the separation is discharged from the liquid outlet of one-level hydrocyclone 2 and is entered secondary hydrocyclone 4.Carry out the secondary separation desanding at 4 pairs of water of secondary hydrocyclone, mainly remove the minor diameter sand grains that contains in anhydrating and separate a small amount of completely major diameter sand grains in one-level hydrocyclone 2, the no sand water after the final separation is discharged from secondary hydrocyclone 4 liquid outlets and is entered muddy water jar 7 through drain pipe 6.Fall on the screen pack 5 after the discharge from one-level hydrocyclone 2, secondary hydrocyclone 4 isolated sands and low amounts of water from sand export, water enters muddy water jar 7 by screen pack 5.Oil-polluted water in the muddy water jar 7 enters clear water jar 9 after filtering through 7 filter boxs 8, and filtrate can be removed impurity and the sump oil in the muddy water effectively, avoids polluting the stratum.Isolated sand is stacked on screen pack 5 when a certain amount of, is gone out by artificial removing, and the clear water in the clear water jar 9 then is used for the circulation well cleanup sand washing.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
