Abstract
The utility model relates to a high efficient air anchor, mainly resolving the problem that although the prior air anchor has a good gas-liquid separation effect, the gas-liquid separated gas suffers a too great resistance when upgoing. The high efficient gas anchor is characterized in that an upper joint (1) and a lower joint (6) are connected with an outer tube (2) through screw threads, liquid inlets (7) are spirally distributed on the wall of the outer tube (2), the wall of the outer tube (2), at lower end of the upper joint (1) is provided with vent holes (8), the lower end of the upper joint (1) is connected with an inner tube (4) communicating therewith, through screw threads, outside of the inner tube (4) is fixedly connected with a liner tube (3), between upper end socket of the liner tube (3) and the liner tube (3) there is provided a plugging head, side wall of the liner tube (3), at the lower end of the plugging head, is provided with vent holes (9), outside of the liner tube (3) is fixedly provided with spiral blades (5), and the wall of the liner tube (3), next to the under surface of the spiral blades (5), is provided with air inlets (10). The high efficient gas anchor not only has a good gas-liquid separation effect, but also enables the gas-liquid separated gas to rise up smoothly.
Description
Technical field:
The utility model relates to the used depassing unit in oil recovery field, oil field, especially efficient gas anchor.
Background technology:
In oil recovery field, oil field,, gas anchor is installed on oil well pump for preventing that gas is pumped in the oil well pump in the well.Cup type and spiral two class gas anchors are mainly adopted in oil pumping well degasification at present.In actual use, cup type gas anchor is owing to reasons in structure, and cup type gas anchor gas-liquid separation effect is poor, but gas is up effective after the gas-liquid separation; Spiral gas anchor is owing to reasons in structure, and spiral gas anchor gas-liquid separation effect is good, but the up suffered resistance of gas is big after the gas-liquid separation, and like this, the degassing effect of two kinds of gas anchors all has certain limitation, and then influences the gas anchor degassing effect.
The utility model content:
Good in order to solve existing gas anchor gas-liquid separation effect, but the big problem of the up suffered resistance of gas after the gas-liquid separation.The utility model provides a kind of efficient gas anchor.This efficient gas anchor not only gas-liquid separation effect is good, and gas is up smooth and easy after the gas-liquid separation.
The technical solution of the utility model is: this efficient gas anchor comprises top connection, outer tube, bushing pipe, interior pipe, helical blade and lower contact.Outer by the outer tube that has been threaded between top connection and the lower contact, spiral is distributed with inlet opening on the outer tube wall, on the outer tube wall of top connection lower end steam vent is arranged; The interior pipe of top connection lower end by being threaded and communicating with it; In the pipe external fixation be connected with bushing pipe, between bushing pipe upper end and the interior pipe block head is arranged, on the lower end liner sidewall of block head venthole is arranged, the bushing pipe external fixation has helical blade, being close to below the nearly helical blade has air inlet on the bushing pipe wall.
The utlity model has following beneficial effect: this efficient gas anchor has steam vent because employing spiral on outer tube wall is distributed with inlet opening on the outer tube wall of top connection lower end; The interior pipe of top connection lower end by being threaded and communicating with it; In the bushing pipe that connects of pipe external fixation, between bushing pipe upper end and the interior pipe block head is arranged, on the lower end liner sidewall of block head venthole is arranged, the bushing pipe external fixation has helical blade, being close to below the nearly helical blade has optimizing structure of air inlet on the bushing pipe wall.Utilize the inlet opening on the outer tube wall that well liquid is sucked this efficient gas anchor, well liquid is descending along the helical blade rotation, and by being advanced in the pump on the interior pipe.Gas enters in bushing pipe and the core pipe up by the air inlet on the bushing pipe, be discharged in the oil jacket annular space gas is smooth and easy by air inlet, venthole and steam vent.Owing to adopt bushing pipe and interior pipe to form independently independently well liquid data feedback channel of gas data feedback channel and interior pipe, thereby not only gas-liquid separation effect is good, and the gas after the gas-liquid separation is up smooth and easy, the degassing efficiency height, reached even more ideal degassing effect, simultaneously simple in structure.Not only gas-liquid separation effect is good for this efficient gas anchor thus, and gas is up smooth and easy after the gas-liquid separation.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-top connection among the figure, 2-outer tube, pipe in the 3-bushing pipe, 4-, 5-helical blade, 6-lower contact, 7-inlet opening, 8-steam vent, 9-venthole, 10-air inlet.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings, this efficient gas anchor comprises top connection 1, outer tube 2, bushing pipe 3, interior pipe 4, helical blade 5 and lower contact 6.Outer by the outer tube 2 that has been threaded between top connection 1 and the lower contact 6, spiral is distributed with inlet opening 7 on outer tube 2 middle wall, on top connection 1 lower end outer tube 2 walls steam vent 8 is arranged; The interior pipe 4 of top connection 1 lower end by being threaded and communicating with it; Interior pipe 4 external fixation are connected with bushing pipe 3, between bushing pipe 3 upper ends and the interior pipe 4 block head are arranged, and on lower end bushing pipe 3 sidewalls of block head venthole 9 are arranged, and bushing pipe 3 external fixation have helical blade 5, and being close on nearly helical blade 5 following bushing pipe 3 walls has air inlet 10.
During actual the use:
Should efficient gas anchor lower contact 6 usefulness plugs directly block or, should be connected the pump lower end by efficient gas anchor again, in the lower going-into-well, can normally use with blocking with plug behind the lengthening tail pipe.Behind the priming pump, under the effect of the pumping power of pump, well liquid enters the annular space that outer tube 2 and bushing pipe 3 are formed by inlet opening 7, after entering annular space, well liquid can only quicken descending along the helical blade rotation of design between outer tube 2 and bushing pipe 3, in centrifugal power, flow velocity increases under the acting in conjunction of pressure decline power, portion gas is separated from well liquid, because specific gravity of gas is little, bubble can be up, when gas is up to the helical blade bottom, enter the exhaust passage that bushing pipe 3 and interior pipe 4 formed by air inlet 10 after, be up to bushing pipe 3 tops, be discharged in the oil jacket annular space by the steam vent on venthole on the bushing pipe 39 and the outer tube 8 at last.When the well liquid after the preliminary gas-liquid separation continues when descending, behind the next stage helical blade, same effect can make the gas in the well liquid further be separated, and pipe 4 is up in entering at last by the well liquid after the multi-stage separation, enter in the pump, finally given rise to manifold of ground.Thereby both guaranteed good gas-liquid separation effect, improve gas again greatly and separate and discharge efficient.
This efficient gas anchor has been obtained remarkable result by The field.
