Abstract
The invention relates to the field of oil-gas field mining machines, in particular to a cyclone sand washing device used in sand washing operation of a horizontal well of an oil-gas field. The cyclone sand washing device is characterized in that a sand washing device body is arranged at the bottom in a sleeve, and a spiral groove is arranged outside the sand washing device body; the sand washing device body is placed in the position of a horizontal sand settling section at the bottom in the sleeve or the position within 0.5m to the sand surface of a straight well section of the sleeve; a connecting head is arranged at the upper end of the sand washing device body; the sand washing device body is hollow, and open pipy structures are arranged at two ends of the sand washing device body; and the outer diameter of the spiral groove is smaller than the inner diameter of the sleeve. The invention provides the cyclone sand washing device which is high in sand washing efficiency and can thoroughly clear sand settled at the bottom of the sleeve.
Description
Technical field
The present invention relates to the exploitation of oil-gas field mechanical field, particularly the eddy flow sand washing machine that uses in the oil gas field horizontal well sand washing operation.
Background technology
In recent years along with the increasing of oil-gas field development dynamics, the horizontal well proportion is increasing, and the corresponding horizontal downhole tool develops hysteresis relatively, and the sand setting of existing sand flushing tool inefficiency, particularly sleeve bottom in the sand washing operation of horizontal oil gas is difficult to be removed.Thus, it is a kind of simply, efficiently to press for exploitation, is applicable to the sand flushing tool of horizontal well.
Summary of the invention
The purpose of this invention is to provide a kind of sand washing efficient height, can thoroughly remove the eddy flow sand washing machine of sleeve bottom sand setting.
The technical solution adopted for the present invention to solve the technical problems is: design a kind of eddy flow sand washing machine, it is characterized in that: this sand washing machine body places the bottom in the sleeve pipe, and the sand washing machine body exterior has helicla flute.
Described sand washing machine body place the horizontal sand setting fragment position of sleeve pipe inner bottom part or sleeve pipe straight well section apart from the sand face less than 0.5m with interior position.
There is connector the upper end of described sand washing machine body.
Described sand washing machine body is the tubular structure of hollow and both ends open.
Described spiral fluted external diameter is less than the internal diameter of sleeve pipe.
Described spiral fluted structure is trapezoidal triple thread, lead of screw between 300mm-400mm, the bearing down on one and the helicoid round-corner transition of three-way helix.
The invention has the beneficial effects as follows: by body helicla flute shape design sand washing machine, when carrying out the inverse circular sand washing adapter operation, liquid can form the current of rotation at a high speed by this instrument, rotation current have at a high speed improved the efficient of sand washing greatly, particularly can thoroughly remove the sand setting of sleeve bottom.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of embodiment;
Fig. 2 is a sand washing machine body end structural representation.
Among the figure: 1, sleeve pipe; 2, sand washing machine body; 3, helicla flute; 4, connector.
The specific embodiment
Shown in the structural representation of this eddy flow sand washing machine of Fig. 1, Fig. 2, this sand washing machine body 2 places the bottom position in the sleeve pipe 1, and there is helicla flute 3 sand washing machine body 2 outsides, and there is connector 4 upper end of sand washing machine body 2.
This sand washing machine body 2 place the horizontal sand setting fragment position of sleeve pipe 1 inner bottom part or sleeve pipe 1 straight well section apart from the sand face less than 0.5m with interior position.
The external diameter of helicla flute 3 is slightly less than the internal diameter of sleeve pipe 1, and sand washing machine body 2 is the tubular structure of hollow and both ends open.
The structure of the helicla flute 3 of present embodiment is trapezoidal triple thread, lead of screw between 300mm-400mm, the bearing down on one and the helicoid round-corner transition of three-way helix.
The anti-circulation during kill job, the connector 4 of sand washing machine body 2 by the upper end carrier pipe that has been threaded, sand washing machine body 2 is carried and is fixed to bottom in the sleeve pipe 1 by carrier pipe, this moment, fluid was under the effect of 2-3MPa pressure, flow with 200-300L/min enters in the sleeve pipe 1, when fluid is flowed through sand washing machine body 2, under the effect of helicla flute 3, form rotary water current at a high speed, rotary water current can wash away the sand setting of sleeve pipe 1 bottom to the low side opening part of sand washing machine body 2, and finally under reverse circulating effect, discharge through carrier pipe by the hollow cavity of sand washing machine body 2, rotation current have at a high speed improved the efficient of sand washing greatly, particularly can thoroughly remove the sand setting of sleeve bottom.
