Abstract
An oil well air-lock-preventing oil pumping pipe column is characterized in that the upper end of an upper eccentric nut is in threaded connection with a oil pipe, the eccentric projection position of the upper eccentric nut is provided with three grooves in the axial direction and an air vent hole communicated with the inner cavity, the inner hole on the lower end of the upper eccentric nut is in screwed connection with an inner guide pipe, and the lower end of the outer body thereof is respectively in screwed connection with a gas anchor outer barrel, an outer barrel connecting body, a screen pipe, a gas anchor lower outer barrel and a lower connector; the lower end of the inner guide pipe is connected with a guide pipe coupling and a guide pipe body welded with a spiral fin, and the lower end thereof is connected with the guide pipe coupling and the guide pipe. The beneficial effect of the utility model is that the oil well air-lock-preventing oil pumping pipe column makes the air-lock-preventing effect of the pumping well pump with high-gas-content be more obvious, further improves the oil and gas production rate, reduces the production cost of the oil well, and has important economic value on the oil-field development.
Description
Technical field
The utility model relates to the comprehensive gas-tight pumping pipe string of a kind of oil well, belongs to the technical field of the oil well gas-tight aspect of oil field oil pumping usefulness.
Background technology
The oil field is in the anti-gas lock implementation process of oil well pump at present, because of its gas anchor divided gas flow poor reliability, efficient is low, cause oil well pump gas lock situation to take place often, had a strong impact on the ordinary production of oil well, caused and cause frequent clean-out service, a large amount of flushing fluids infiltration oil reservoirs cause the oil reservoir injury and open and take out a large amount of drainings, rate when having seriously influenced oil well production, and significantly increased the oil well production cost.
Summary of the invention
At the deficiency that above-mentioned technical problem exists, the purpose of this utility model provides a kind of [ZBF/ZFQG-90] the comprehensive gas-tight pumping pipe string of oil well.
The technical solution of the utility model is as follows:
The comprehensive gas-tight pumping pipe string of a kind of oil well comprises, two ends up and down of the present utility model are connected with oil-piping.It is characterized in that: the upper end of eccentric top connection (1) is connected with tubing round thread, the steam vent that is not equipped with three axial grooves at the eccentric protruding place of eccentric top connection (1) and communicates with inner chamber, the endoporus and interior mozzle (2) screwed connection of eccentric top connection (1) lower end, its ectosome lower end respectively with gas anchor urceolus (4), urceolus connector (5), screen casing (6), urceolus under the gas anchor (8), lower contact (9) screwed connection, the lower end of interior mozzle (2) connects mozzle box cupling (3) and connects the diversion tube that is welded with flight (7), and its lower end connects mozzle box cupling (3) and mozzle.
Three grooves that the protruding place of described off-centre is provided with, its groove depth 25mm, groove width 20mm is provided with two holes and is connected with inner chamber body in its each groove.
Described screen casing (6) is cloth five row holes in 120 ° of angles of circumferential discontinuity, and its aperture is 8mm, spacing 60mm, and every row cloth 18 holes, with corresponding flight (7) diversion tube, its flight (7) helical pitch 70mm, cloth weldering length is 840mm.
The beneficial effects of the utility model are: make high gassiness oil pumping well pump gas-tight lock effect more remarkable, the Accumulation of Hydrocarbon productive rate can further improve, and the oil well production cost further reduces, and has important economic worth in oil field development.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Among the figure: urceolus, 9 lower contacts under mozzle, 3 mozzle box cuplings, 4 gas anchor urceolus, 5 urceolus connectors, 6 screen casings, 7 flights, 8 gas anchors in the 1 eccentric top connection, 2.
The specific embodiment
As shown in Figure 1, the upper end of eccentric top connection 1 is connected with tubing round thread, is provided with three axial grooves at the eccentric protruding place of eccentric top connection 1, its groove depth 25mm, and groove width 20mm is provided with two holes and is connected with inner chamber body in described each groove.The endoporus and 2 screwed connections of interior mozzle of eccentric top connection 1 lower end.Urceolus 8, lower contact 9 screwed connections under its ectosome lower end and gas anchor urceolus 4, urceolus connector 5, screen casing 6, the gas anchor, the lower end of interior mozzle 2 connects mozzle box cupling 3 and connects the diversion tube that is welded with flight 7, and its lower end connects mozzle box cupling 3 and mozzle.Cloth five row holes in 120 ° of angles of the circumferential discontinuity of screen casing 6, the aperture is 8mm, spacing 60mm, every row cloth 18 holes, with corresponding flight 7 diversion tubes, its flight 7 diversion tubes and the flight helical pitch 70mm that welds mutually, the length of flight 7 is 840mm.
Its operating principle: gas anchor of the present utility model is designed to off-centre and pours in down a chimney frame mode, and its anchor urceolus screen casing 6 liquid sucting ports now are designed to 120 ° of open interiors of one-sided section by former circumferencial direction perforate, and keeps 180 ° of azimuths with the eccentric joint convex shoulder.The interior oil gas body of sleeve pipe enters the upper surface of spirochetal flight 7 during oil well pump oil pumping work through screen casing side opening water conservancy diversion, the oil gas body is through conveyor screw centrifugation and action of gravity, upper end exhaust opening discharge enters casing annulus to divided gas flow along gas anchor inner chamber upstroke to eccentric joint, the liquid that separates is settled down to urceolus 8 cavity air under the gas anchor under action of gravity, its gas anchor inner central tube suction inlet inserts the interior bottom of urceolus 8 pipes under the gas anchor deeply, its underpart liquid is entered in the pump line on pump standing valve top by interior mozzle 2 lower end intakes by oil well pump, this gas anchor frame mode and operating principle be the gas in the separating oil gas-liquid effectively, prevents and get rid of the generation of oil well pump gas lock.
