Description
Technical field
The utility model relates to a kind of desanding sediment outflow plant equipment that is used for oilfield oil well sand washing operation.
Background technology
At present, during oil-water well circulation sand washing operation, the sand water that returns out advances the ground earth storage usually, and what have enters common sand washing pond, ground, and post precipitation continues the circulation sand washing; Though having taked of having comparatively advanced eddy flow desanding device, but because unreasonable structure, there are many disadvantages and can't realize that sand water thoroughly separates, after the sand water that returns out enters earth storage, the circulation sand washing can not be constituted,, ground pollution can be caused though can remove silt particle up hill and dale, need many tank car roping sand cleaning fluids, cause the waste of serious sand cleaning fluid and tank car; Enter ordinary cycle sand washing pond, ground, though saved sand cleaning fluid and roping vehicle, but because the last waterline of sand water out pipeline that goes out from the well internal return and pump same pond, will make some fine silts reenter circulation sand washing in the well, final be difficult to the interior silt particle of well thoroughly clean; The pond of being furnished with the eddy flow desanding device, 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 be separated more up hill and dale, above-mentioned silt particle still can occur and go into the situation of well circulation, sand washing operating efficiency and effect are reduced.
The purpose of this utility model is to provide a kind of can improve oil-water well sand washing operating efficiency and effect greatly, and can reduce the oil-water well sand washing operation desanding sand removing device of sand removal labour intensity, saving sand cleaning fluid consumption and tank car expense, minimizing environment pollution.
Summary of the invention
The utility model is to realize like this.This kind desanding sand removing device is made up of sand storage tank, cyclic flusher liquid pool, entrance gate, manifold, sediment outflow gate, helical blade type sand removing device, adjustment bypass damper plate, sand block dividing plate, taper gate, one-level hydrocyclone, secondary eddy flow desilter, fixed support, rotation steering wheel, gear, improves oil-water well sand washing operating efficiency and effect by adopting two-stage eddy flow desanding device and helical blade type sand removing device.Before the use, the inlet line of this device sand storage tank is connected with the outlet line of well head.During work, the sand cleaning fluid that returns out from the oil-water well well head through this device inlet line from the side tangent line at first enter the one-level hydrocyclone, after big particle diameter sand eliminating, enter the secondary eddy flow desilter of two parallel connections from one-level hydrocyclone upper end through manifold, further remove fine silt and shale composition.After this, the sand cleaning fluid that contains a small amount of silt particle partly enters in the sand storage tank from the bottom of two-stage eddy flow desanding device, precipitation through the long period, silt particle is deposited in the sand storage tank, the sand cleaning fluid that does not contain silt particle overflows in the circulatory pool, directly enter the circulatory pool from the top outlet of the eddy flow desanding device most of clean sand cleaning fluid that confluxes, guarantee that circulation sand washing operation continues to carry out.After sand washing finished, the clean sand cleaning fluid on sand storage tank top can overflow in the circulatory pool by adjusting flashboard, at last clean sand cleaning fluid is squeezed into the station of recovering the oil.Be deposited on the silt particle in the sand storage tank,, long-pending sand discharged sand storage tank, guarantee that circulatory pool is interior clean, be convenient to use next time by manpower rotating screw vane type sand removing device.
The utility model is compared with existing eddy flow desanding pond and is had the following advantages:
1, desanding device lower end clearance hole is in uncovered state all the time, guarantees that the sand-laden fluid in the hydrocyclone is in rotation sedimentation state all the time, helps sand water and thoroughly separates; 2, sand storage tank separates with circulatory pool, and the sand-laden fluid that enters sand storage tank is further precipitated, and guarantees that silt particle all is deposited in the sand storage tank, and the sand cleaning fluid of cleaning then overflows in the circulatory pool, helps improving the sand washing quality; 3, the structure that adopts the desilter of large diameter desander and minor diameter to be used helps thin silt particle and separates; 4, adopt spiral fettling installation, do not need the people to enter and use the spade sand removal in the pond, can alleviate sand removal labour intensity.Utilize this device can improve oil-water well sand washing operating efficiency and effect greatly, reduce cost, be suitable for and apply.
