Abstract
The utility model relates to a hydraulic vortex sand separator for pumping oil in the oil field, which is composed of an upper contact, a leptospira, a conical tube, an outer tube and a lower connect, wherein the lower part of the upper contact is connected with the upper part of the outer tube, the leptospira and the conical tube are arranged below the screw thread on the upper part of the outer tube, and the lower part of the outer tube is connected with the lower contact. The leptospira is provided with a screwing key of which the outer surface contacts the inner wall of the outer tube, and thus a screw flow channel is formed. When a pumping well operates, the stratum liquid enters the screw flow channel through a liquid-feeding bore of the outer tube, which enables the liquid to rotate when the liquid flows downwards along the screw flow channel; the rotation speeds up when the liquid passes through the conical tube, and thus, the centrifugal pull is generated; the sand in the liquid is separated under the function of the centrifugal pull, and the sand falls downwards into a desilting tail tube on the lower part of the lower contact; the liquid which is desanding enters the pump along the interior of the leptospira, and the liquid sand which enters the pump is reduced, which solves the problem that an oil pump is embedded or abraded by sand; the production halts of the oil well can be avoided, the period of production of the oil well is extended, and the cost of operation is reduced.
Description
One, technical field
The utility model relates to a kind of fluid power eddy flow sand separator of oil field oil pumping usefulness, belongs to engineering goods.
Two, background technology
In the pumpingh well in oil field, contain a certain amount of sand grains in the well liquid that flows out from the stratum, when sand grain content is higher, will influence oil well production, cause pump to bury oil well pump or sand grains wearing and tearing oil well pump, cause that oil well can not be produced or with short production cycle, produce great economic loss.The way that present oil field addresses this problem is a sand device under oil well pump, there are many problems in used sand device, can inside and outside sand device, form pressure reduction on the one hand, cause energy loss, pressure reduction also makes sand device damage easily, and sand device stops up easily on the other hand, causes oil well not fuel-displaced, need operation just can resume production, thereby increase operating cost.
Three, summary of the invention
The purpose of this utility model is a kind of fluid power eddy flow sand separator of design, make it be connected in oil well pump following time, well liquid is played the effect that separates sand grains before advancing pump, thereby the sand grains that enters in the oil well pump is reduced, avoid sand to bury oil well pump or sand grains wearing and tearing oil well pump, avoid oil well to stop production, prolong the oil well production cycle, reduce operating cost.
The purpose of this utility model is achieved in that it is made up of top connection, conveyor screw, conical tube, outer tube, lower contact.The top connection bottom connects with outer tube top, under the screw thread of outer tube top conveyor screw, conical tube is installed, and conveyor screw is on conical tube, and the outer tube bottom connects lower contact, and conical tube is on lower contact.Under the screw thread of outer tube top inlet opening is arranged.Screw key is arranged on the conveyor screw, and the screw key external surface contacts with outer tube wall, thereby forms helical flow path.When pumpingh well is produced, stratum liquid enters in the helical flow path from the inlet opening on the outer tube, make liquid when flowing downward, produce rotation along helical flow path, liquid rotation by conical tube the time is accelerated, make it produce centrifugal force, under centrifugal action the sand grains in the liquid is separated, sand grains is in the sand setting tail pipe that falls into the lower contact bottom, and the liquid after the desanding then enters in the pump along conveyor screw inside.
The beneficial effects of the utility model are: reduced the liquid sand grains that enters in the pump, solved the problem that sand buries oil well pump or sand grains wearing and tearing oil well pump, can avoid oil well to stop production, prolonged the oil well production cycle, reduced operating cost.
Four, description of drawings
Accompanying drawing is the utility model general structure half sectional view.
In the drawings: the 1st, top connection, the 2nd, conveyor screw, the 3rd, conical tube, the 4th, outer tube, the 5th, lower contact.Be that the utility model is made up of top connection 1, conveyor screw 2, conical tube 3, outer tube 4, lower contact 5.
Five, the specific embodiment
As shown in the figure, top connection 1 bottom connects with outer tube 4 tops, and conveyor screw 2, conical tube 3 are installed under the outer tube 4 top screw threads, and conveyor screw 2 is on conical tube 3, and outer tube 4 bottoms connect lower contact 5, and conical tube 3 is on lower contact 5.Under the outer tube 4 top screw threads inlet opening is arranged.On the conveyor screw 2 screw key is arranged, the screw key external surface contacts with outer tube 4 inwalls, thereby forms helical flow path.When pumpingh well is produced, stratum liquid enters in the helical flow path from the inlet opening on the outer tube 4, make liquid when flowing downward, produce rotation along helical flow path, liquid rotation by conical tube 3 time is accelerated, make it produce centrifugal force, under centrifugal action the sand grains in the liquid is separated, sand grains is in the sand setting tail pipe that falls into lower contact 5 bottoms, and the liquid after the desanding then enters in the pump along conveyor screw 2 inside.
