Abstract
The utility model discloses an electric pump anti-sand device namely a new type anti-sand device above the electric oil-immersed pump (refers to electric pump) used for oil extraction in oilfields. The pump comprises a lifting short pitch, a variable buckle joint,a flow joint, a stabilizing ring, a sand blocking ring, an inner pipean outer pipe and a low joint connected each other. The lifting short pitch, the lower joint are connected with an oil pipe; the inner pipe and outer pipe make up a sand storage cavity; a sand blocking valve is installed in the stabilizing ring, which can move up and down; the inner pipe is arranged with a cleaning hole; the lower part of the sand blocking valve is made in cone shape. The sand-blocking valve prevents the accumulated sand inside of the production pipe column on top of the anti-sand device from entering into the electric pump and leads the accumulated to enter into the sand storage cavity.
Description
Technical field
The utility model relates to a kind of novel electric pump sand control installation: the sand control installation on a kind of electric submersible pump (abbreviation electric pump) that is positioned at oil field oil recovery usefulness.
Background technique
The oil field electric motor drive oil pump system is that mechanical oil recovery is one of topmost means.At sand well, carry sand grains with the drawing liquid of electric pump extraction and enter in the flow string, when sand fallout speed during greater than the pumping liquid rate of climb, the sand grains that the flow string inner fluid carries will be deposited on the electric pump, causes electric pump sand card.
Summary of the invention
When recovering the oil in order to solve sand well, the problem of electric pump sand card, the utility model provides a kind of electric pump top that places to link to each other with flow string, can prevent the new type of sand prevention device of sand card electric pump.
The utility model solves its technical problem and takes following design proposal to realize: this novel electric pump sand control installation that can prevent the sand card is coupled to each other and is formed by lifting sub, change snapping head, water conservancy diversion joint, centering ring, sand block valve, interior pipe, outer tube, lower contact.Lifting sub, lower contact link to each other with oil pipe; Interior pipe constitutes sand storage cavity with outer tube; The sand block valve is contained in the centering ring, can move up and down; Interior pipe has the sand removal hole; Sand block valve body bottom is taper.The sand block valve prevents that the sand setting in the flow string of new type of sand prevention device top from entering electric pump, and the guiding sand setting enters sand storage cavity.
The beneficial effects of the utility model are: 1, when sand fallout speed during greater than the pumping liquid rate of climb, sand setting enters sand storage cavity, has prevented that sand setting enters electric pump in the flow string of new type of sand prevention device top; 2, during the electric pump ordinary production, can constantly remove the long-pending sand of sand storage cavity by the sand removal hole of interior pipe, life cycle prolongs.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structure diagram.
Among the figure: 1 lifting sub, 2 becomes pipe, 7 outer tubes, 8 lower contacts, 9 sand storage cavities, through hole 41 in snapping head, 3 water conservancy diversion joints, 4 centering rings, the 5 sand block valves, 6.
Embodiment
Referring to Fig. 1, the utility model sand control installation is made up of lifting sub 1, change snapping head 2, water conservancy diversion joint 3, centering ring 4, sand block valve 5, interior pipe 6, outer tube 7, lower contact 8, sand storage cavity 9.
Lifting sub 1, change snapping head 2, water conservancy diversion joint 3, centering ring 4, sand block valve 5, interior pipe 6, outer tube 7, lower contact 8 are coupled to each other composition.
Lifting sub 1 is the functional part that connects with the top flow string;
Become snapping head 2, water conservancy diversion joint 3 according to lifting rate design diameter of bore, guarantee that pumping liquid has enough circulation areas;
Interior pipe 6 and outer tube 7 are connected in the lower contact 8 jointly, and interior pipe 6 internal diameters are consistent with the production tube internal diameter, and the annular space between interior pipe 6 outer walls and outer tube 7 inwalls forms a sand storage cavity 9; Interior pipe 6 has number and clears sand hole; Lower contact 8 also is the functional part that connects with the bottom electric pump.
Centering ring 4 has the passage that drawing liquid that through hole 41 is extraction and sand setting enter sand storage cavity 8.
Sand block valve 5 can upper and lower motion in centering ring 4.When electric pump quits work, pipe 6 tops in sand block valve 5 drops to, the drawing liquid top outlet of pipe 6 extraction in sealing; During electric pump work, the drawing liquid passage of extraction is formed at sand block valve 5 up and interior pipes 6 tops.
All pass through scyewed joint between the above-mentioned parts.
Its working principle is: this electric pump new type of sand prevention device lower end is linked to each other with electric pump, top links to each other with oil pipe, when normal pumping, the drawing liquid passage of extraction is formed at sand block valve 5 up and interior pipes 6 tops, the drawing liquid of extraction enters in the production tube by the through hole 41 of drawing liquid passage and centering ring 4, and by the sand removal hole sand setting of sand storage cavity 8 is discharged ground with the drawing liquid of extraction.When electric pump quits work, pipe 6 tops in sand block valve 5 drops to, the drawing liquid top outlet of pipe 6 extraction in sealing, and the guiding sand setting enters sand storage cavity 8.
