Description
Technical field
The present invention relates to petroleum industry workover treatment technology, specifically a kind of profit sand separating apparatus and method.
Background technology
Flushing fluid can be used for rinsing the borehole wall, remove sediment, silt sand or dead oil block in well, played during workover treatment
Very important effect.Flushing fluid, which enters well, to be needed to meet the requirement such as suspended solid, particle diameter intermediate value, oil content, and this is required
In operation process, the flushing fluid that continuous circular treatment returns from well is to reach into well requirement, so as to accomplish flushing fluid
Recycle.The flushing fluid treatment equipment used now is mostly well-washing truck, is more devices such as set desanding, oil removing, air supporting
Integration apparatus.But due to the limitation of its structure, it is difficult to carry out the group of different disposal device according to different well's conditionses with suiting measures to local conditions
Close, therefore be not easy to be optimal treatment effect.
The content of the invention
It is an object of the invention to provide a kind of profit sand separating apparatus and method, realized at workover treatment scene water, sand,
Oily three phase separation；Skid-mounted type structure, it is convenient to be connected with other well-flushing liquid processing devices；Modular unit, it is easily changed.
In order to reach above-mentioned purpose, present invention employs following technical scheme, a kind of profit sand separating apparatus, including tank
Body, cyclone separator, the cyclone separator are arranged in tank body, and there is cyclone separator a feed tube to draw tank body
Outside, the tank wall opens up delivery port, and the tank body upper end opens up oil-out.
There is a water-oil mixture to export for the cyclone separator upper end.
The cyclone separator lower end has one and goes out sandpipe and draw outside tank body.
It is described go out sandpipe on set and shake out control valve.
A longitudinally disposed baffle plate in the tank body, block between water-oil mixture outlet and delivery port, the baffle plate
Bottom opens up water passage.
In order to reach above-mentioned another object, present invention employs following technical scheme, a kind of profit sand separation method, it is walked
Suddenly it is that the flushing fluid recycled in well enters cyclone separator by feed tube, in cyclone separator, the sand isolated gathers
Collect in the bottom of cyclone separator, when sand aggregation is enough, open control valve of shaking out, the sand isolated is arranged by going out sandpipe
Go out；And the water-oil mixture isolated is discharged into tank body by the upper outlet of cyclone separator, in tank body, water and it is oily because
It is automatically separated for gravity, oil is gathered in top, is discharged by oil-out, and the baffle plate bottom that water then passes through enters the another of tank body
Side, then discharged by delivery port.
Compared to prior art, the invention has the advantages that：
Include cyclone desanding device and baffle plate inside the separator.The effect of cyclone desanding device is separation of solid and liquid,
Leakage fluid dram is arranged at top, and there is sand removing hole bottom, is provided with valve at sand removing hole, can control the opening and closing of sand removing hole.At eddy flow
Liquid after reason enters next chamber after leakage fluid dram outflow, and the chamber is provided with a baffle plate, baffle plate top and the right and left difference
It is fixedly connected with cavity, bottom is hanging, i.e., cavity is divided into two rooms of bottom connection by baffle plate.Oil and water after eddy flow processing exist
Because gravity separates in the cavity, oily on top, water is in bottom.The oil on top is discharged by oil discharge outlet, the water warp of bottom
After entering the opposite side of cavity by baffle plate bottom, discharged from discharge outlet.
In a word, advantages of the present invention：1st, water, sand, oily three phase separation are realized at workover treatment scene；2nd, skid-mounted type structure,
It is convenient to be connected with other well-flushing liquid processing devices；3rd, modular unit, it is easily changed.
Brief description of the drawings
Fig. 1 is a kind of structural representation of profit sand separating apparatus of the present invention.
In figure：1st, feed tube, 2, oil-out, 3, delivery port, 4, go out sandpipe, 5, control valve of shaking out, 6, cyclone separator, 7,
Baffle plate.
Embodiment
Detailed description for the present invention and technology contents, coordinate brief description of the drawings it is as follows, but accompanying drawing only provide reference with
Purposes of discussion, not it is used for being any limitation as the present invention.
According to Fig. 1, a kind of profit sand separating apparatus, including tank body, cyclone separator 6, the cyclone separator are arranged on
In tank body, and there is cyclone separator a feed tube 1 to draw outside tank body, and the tank wall opens up delivery port 3, the tank
Body upper end opens up oil-out 2.There is a water-oil mixture to export for the cyclone separator upper end.The cyclone separator lower end
Go out sandpipe 4 with one and draw outside tank body.It is described go out sandpipe on set and shake out control valve 5.Longitudinally disposed one in the tank body
Individual baffle plate 7, block between water-oil mixture outlet and delivery port, the baffle bottom opens up water passage.
During workover treatment, the flushing fluid recycled in well enters the device by feed tube 1, immediately into cyclonic separation
Device 6, in cyclone separator 6, the sand isolated is gathered in the bottom of cyclone separator 6, when sand aggregation is enough, opens out
Sand control valve 5, the sand isolated are discharged by going out sandpipe 4.And the water-oil mixture isolated passes through the top of cyclone separator 6
Outlet is discharged into tank body, and in tank body, because gravity is automatically separated, oil is gathered in top, passes through oil-out 2 for water and oil
Discharge, water then enter the opposite side of tank body by 7 baffle plate bottom, then discharged by delivery port 3.
If the liquid that oil-out 2 and delivery port 3 are discharged needs further processing, can continue to connect other in the outlet
Processing equipment carries out subsequent treatment, until result meets to require.
The separator can connect with other well-flushing liquid processing devices as requested, so as to be optimal treatment effect.
Presently preferred embodiments of the present invention is the foregoing is only, is not used to limit the scope of the claims of the present invention, other are with this
The equivalence changes of the patent spirit of invention, it all should all belong to the scope of the claims of the present invention.
