Separation is that liquid treatment technology is adopted in a kind of emerging oil field under oil-water well, and oily-water seperating equipment is mounted on shaft bottom by it,
Most water in separation production fluid are directly injected into stratum, and a part of liquid that only will be enriched in oil gives rise to ground, to pole
The earth alleviates the burden of production fluid water treatment system, can save corresponding enormous expenditure, extend the production life of well of oil well, because
This technology causes the great attention of petroleum industrial circle and correlative technology field in recent years.
Current downhole oil-water separation mainly has gravity type and two kinds centrifugal, such as patent document CN101025080A, more glasss
The method that equal flow type downhole separation system realizes high water-cut well single-well injection-production, it is existing using natural subsidence Gravity separate
Problem is that discharge capacity is small, the sedimentation separation time is longer, discontinuously；Patent document CN2931780Y, a kind of downhole separation system are adopted
With conical centrifuge formula separator, cone separator has side entrance, and that there are flow velocitys is big, erosion is big, crushing is big and uniprocessing
The problems such as small is measured, can only be in parallel if being used for huge discharge, once one of damage, will result in failure；Patent document CN
106693447A, cyclone separator and the patent document CN105999770A in the same direction of two kinds of different densities media, a kind of grease
Spiral stream guidance separator, scheme disclosed in two documents all use pipe-type rotary-flow to detach, and have that shunting is smaller, separation water contains
The shortcomings of oil cut rate is higher cannot meet the needs of high water cut oil field exploitation.
Invention content

Specific implementation mode
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and coordinate attached drawing
Detailed description are as follows：
Referring to Fig. 1, a kind of pipe type oil-water separator, including shell 5, the upper end of the shell 5 is separation water out,
Lower end is mixed liquor import 7, is equipped with the pipe cyclone 6 being coaxially arranged and derotator 4 from top to bottom in the shell 5,
Interval is equipped between the pipe cyclone 6 and the derotator 4, the pipe cyclone 6 and the derotator 4 are equipped with external water conservancy diversion
Blade and center flow tube, the pipe cyclone 6 and 4 outside guide vane of the derotator are oppositely oriented, and center flow tube is opposite,
The lower end of the center flow tube of the pipe cyclone 6 is connect by lower oil outlet bridge logical 12 with flowline 10, in the derotator 4
The upper end of heart flow tube is connect by upper oil outlet bridge logical 9 with the flowline 10.
In the present embodiment, the pipe cyclone 6 and 4 outside guide vane of the derotator and connecing inside the shell 5
It is luminance curve that line, which is touched, in cylinder unwrapping, can improve eddy flow effect.The upper end of the shell 5 is connected with water seating nipple 2 is detached,
The separation water seating nipple 2 is equipped with water outlet 3, and flow, pressure monitoring instrument and stream are equipped in the separation water seating nipple 2
The flow control valve of control valve door, the separation water seating nipple 2 is controlled by controlling cable 1.Above structure is used for
Water yield is controlled, and then controls split ratio, promotes water-oil separating efficiency.The lower end of the center flow tube of the pipe cyclone 6 is successively
It is connect with flowline 10 by the lower oil outlet bridge logical 12 and lower oil outlet seating nipple 11, in the lower oil outlet seating nipple 11
Interior to be equipped with flow, pressure monitoring instrument and flow control valve, the flow control valve of the lower oil outlet seating nipple 11 is logical
Control cable 1 is crossed to be controlled.Above structure ensures fuel-displaced concentration highest, and can be by under control for controlling oil pump capacity
Regulating valve in oil outlet seating nipple selects suitable split ratio, promotes water-oil separating efficiency, realizes oil water separator split ratio
Bigger, separation water oil content be lower or even not oil-containing.Similarly, the upper end of the center flow tube of the derotator 4 passes sequentially through
Oil outlet bridge logical 9 and upper oil outlet seating nipple 8 are connect with flowline 10, and flow, pressure are equipped in the upper oil outlet seating nipple 8
The flow control valve of power monitoring instrument and flow control valve, the upper oil outlet seating nipple 8 is carried out by controlling cable 1
Control.
The operation principle of the present invention：
Underground oil-water mixture is flowed into from mixed liquor import 7 first passes through pipe cyclone 6, since pipe cyclone 6 is equipped with water conservancy diversion
Blade, when oil water mixture flows through, generate tangential velocity, due to oil and water density have differences, cause oil and water obtain from
Mental and physical efforts are different, and the density of water is big, so the distance being thrown out of is farther out, close to the inner wall of shell, and oil is then assembled to center, is formed
One apparent wick, such water are wrapped in oil and are rotationally advancing.Fluid flows through derotator 4 after a distance, due to untwisting
Device and pipe cyclone guide vane direction on the contrary, and outlet it is parallel with shell 5, close to inner wall of tube shell High water cut fluid from rotation change
For PARALLEL FLOW.Fluid so only between pipe cyclone 6 and derotator 4 is rotation, and the smaller oil of density is tightly controlled
In the approximate centerline of this section, one section of thin and long wick is formed, and pipe cyclone 6 and the upper of derotator 4 have center flow tube
It is connect with flowline 10, therefore the wick of high concentration can flow out.And it can be gone out under by adjusting upper oil outlet seating nipple 8
The flow channels of hydraulic fluid port seating nipple 11 control wick flow pass.When underground oil-water mixture oil content is high, the oil of formation
Core is thicker, can open the flow channels of oil outlet seating nipple 8, lower oil outlet seating nipple 11 simultaneously at this time, while fuel-displaced, and converge
Enter flowline 10；When the oil content of underground oil-water mixture reduces, the wick medium-coarse of formation, under can only opening at this time
The flow channels of oil outlet seating nipple 11, wick only flow into flowline 10 from lower oil outlet bridge logical 12；When underground oil-water mixture
Oil content further decrease, the wick of formation is thinner, can only open the flow channels of upper oil outlet seating nipple 8, wick at this time
Only flowline 10 is flowed into from upper oil outlet bridge logical 9.And the oil content of the separation water after separation has been reduced to very low, can reach
It is directly recycled into the standard on stratum, stratum is recycled by detaching water seating nipple 2 and its water outlet 3.
Although the preferred embodiment of the present invention is described above in conjunction with attached drawing, the invention is not limited in upper
The specific implementation mode stated, the above mentioned embodiment is only schematical, be not it is restrictive, this field it is common
Technical staff under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, may be used also
By make it is many in the form of, within these are all belonged to the scope of protection of the present invention.
