Description

Underground oil-water depurator
Technical field
This utility model relates to oil field development DP technology technical field, particularly to a kind of underground oil-water depurator.
Background technology
At present common screen casing carries out machine and adopts inlet, and oil, water, mud, sand, gas etc. are mixed into pump barrel, and pump efficiency is poor, accident-proneness, to be excused from a college course the phase short.In order to improve machine adopt efficiency stop gas-solid silt particle impact need to improve constantly underground oil-water purity, downhole oil, water, mud, sand, QI excess now separate, available energy can effectively reduce silt particle to sealing property impact and minimizing mechanical wear, improve full level in effective stroke, improve pump efficiency, extend and be excused from a college course the phase, reduce development cost.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of a kind of underground oil-water depurator that can downhole oil, water, mud, sand, QI excess be now separated of developing.
This utility model one underground oil-water depurator, including top connection, reducer pipe A, main pipe, reducer pipe B, lower contact, central canal, flap, inlet opening C, particulate filter, venthole, inlet opening D, dividing plate, check valve, gas storage and transportation room, it is characterized in that: described top connection is fixedly connected by the upper end of reducer pipe A body and main pipe, and the lower end of main pipe is fixedly connected by reducer pipe B and lower contact;Be provided with central canal in the inner side of main pipe, the upper end of described central canal and the lower end inner wall of reducer pipe A are fixedly connected, and the lower end of central canal is positioned at the centre position of main pipe's inside lower end;The centre position outer wall of central canal is provided with spiral flap, the lower end outer wall of central canal is provided with several inlet opening C and particulate filter, the outer wall of described particulate filter and central canal complements one another, and described particulate filter is also in the outside of inlet opening C;The upper end outer wall of main pipe is provided with several venthole, the centre position outer wall of main pipe is provided with several inlet opening D;Between the inner top side and central canal outer wall of main pipe, it is provided with the dividing plate of annular, the left and right sides of dividing plate is provided with check valve;The upper end of described dividing plate forms a gas storage and transportation room sealed with the inwall of main pipe, the outer wall of central canal respectively.
Further, described top connection, main pipe, lower contact, central canal, particulate filter are a kind of cylinder.
Further, described reducer pipe A, reducer pipe B are a kind of conical structure.
Further, described particulate filter is a kind of metal grid.
The beneficial effects of the utility model are: reduce cost, easy to use, and operation principle is simple, has preferable oil, water, mud, sand, gas separating effect simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-top connection, 2-reducer pipe A, 3-main pipe, 4-reducer pipe B, 5-lower contact, 6-central canal, 7-flap, 8-inlet opening C, 9-particulate filter, 10-venthole, 11-inlet opening D, 12-dividing plate, 13-check valve, 14-gas storage and transportation room.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, is not defined scope of the present utility model.
According to Fig. 1: this utility model one underground oil-water depurator, including top connection 1, reducer pipe A2, main pipe 3, reducer pipe B4, lower contact 5, central canal 6, flap 7, inlet opening C8, particulate filter 9, venthole 10, inlet opening D11, dividing plate 12, check valve 13, gas storage and transportation room 14, it is characterized in that: described top connection 1 is fixedly connected by the upper end of reducer pipe A2 body and main pipe 3, the lower end of main pipe 3 is fixedly connected by reducer pipe B4 and lower contact 5;Being provided with central canal 6, the upper end of described central canal 6 and the lower end inner wall of reducer pipe A2 to be fixedly connected in the inner side of main pipe 3, the lower end of central canal 6 is positioned at the centre position of main pipe 3 inside lower end;The centre position outer wall of central canal 6 is provided with spiral flap 7, the lower end outer wall of central canal 6 is provided with several inlet opening C8 and particulate filter 9, the outer wall of described particulate filter 9 and central canal 6 complements one another, and described particulate filter 9 is also in the outside of inlet opening C8;The upper end outer wall of main pipe 3 is provided with several venthole 10, the centre position outer wall of main pipe 3 is provided with several inlet opening D11;Between the inner top side and central canal 6 outer wall of main pipe 3, it is provided with the dividing plate 12 of annular, the left and right sides of dividing plate 12 is provided with check valve 13;The upper end of described dividing plate 12 forms a gas storage and transportation room 14 sealed with the inwall of main pipe 3, the outer wall of central canal 6 respectively.
Further, described top connection 1, main pipe 3, lower contact 5, central canal 6, particulate filter 9 are a kind of cylinder.
Further, described reducer pipe A2, reducer pipe B4 are a kind of conical structure.
Further, described particulate filter 9 is a kind of metal grid.
Operation principle of the present utility model is: borehole fluid enters into the inner side of main pipe 3 from inlet opening D11, borehole fluid is descending by the spiral type flap 7 on central canal 6 outer wall, because the density of solid in fluid is big, heavies enters suspension tail pipe along the inwall of main pipe 3 by lower contact 5, gas density is little, then enter gas storage and transportation room 14 along central canal 6 outer wall check valve 13 of upwards passing through, derive gas storage and transportation room 14 by gas outlet;Liquid filters off microactuator suspension fine grained by particulate filter 9, and microactuator suspension fine grained enters through lower contact 5 under gravity and hangs tail pipe, and liquid then enters central canal 6 by inlet opening C8, and liquid provides clean liquid through top connection 1 for pump.
The beneficial effects of the utility model are: reduce cost, easy to use, and operation principle is simple, has preferable oil, water, mud, sand, gas separating effect simultaneously.
The above embodiment only have expressed a kind of embodiment of the present utility model, but therefore can not be interpreted as the restriction to this utility model scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.
