Abstract
The utility model discloses a gas anchor which comprises a liquid return pipe, wherein a gas anchor outer shell is sleeved on the upper portion of the liquid return pipe, a sand settling pipe is sleeved on the lower portion of the liquid returning pipe, oil baffle plates are respectively arranged on the outer wall of the liquid return pipe and the inner wall of the gas anchor outer shell, a clapboard is arranged between the outer wall of the liquid return pipe and the inner wall of the gas anchor outer shell, the clapboard is located below the oil baffle plates and provided with a liquid discharging hole, the upper portion of the sand settling pipe stretches into the gas anchor outer shell to the clapboard, a liquid inlet is arranged on the upper portion of the gas anchor outer shell, a liquid inlet hole is formed in the upper portion of the sand settling pipe, and a connector of an oil well pump is arranged at the upper end of the liquid return pipe. The gas anchor achieves high-efficiency separation of oil and gas through arrangement of the oil baffle plates, and finally the purpose of increasing production is achieved. Meanwhile, the length of the gas anchor outer shell is shortened, steel materials are saved, cost is lowered, and effect is not affected.
Description
Technical field
The utility model belongs to the extracting device of oil technical field of petroleum industry system, is specifically related to a kind of gas anchor.
Background technology
In recovering the oil now, have the large oil well of a lot of gas, gas enters and causes pump efficiency to reduce in the oil well pump, forms gas lock when serious, and oil be can't pump out, and oil recovery rate descends.For solving the above problems, many oil wells all are to carry out gas, liquid separation with gas anchor for a long time.The operating principle of traditional all kinds of down-holes gas anchor is to allow mixed liquor enter in a large number gas anchor, various runners by gas anchor make fluid carry out gas, liquid separation in convolution is flowed, but the separating effect of this method is very low, especially all the more so greater than the fluid of 2MPas to down-hole viscosity, be difficult to reach the purpose that improves pump efficiency, increases output in the field.
Summary of the invention
The purpose of this utility model provides a kind of gas anchor, has solved the problem of gas, liquid inferior separating effect in the prior art.
The technical scheme that the utility model adopts is: a kind of gas anchor, comprise and return the liquid pipe, returning liquid pipe top cover has the gas anchor shell, and the bottom cover has sand sediment pipe, returns liquid pipe outer wall and the gas anchor outer casing inner wall is respectively equipped with oil baffle, return between liquid pipe outer wall and the gas anchor outer casing inner wall and be provided with dividing plate, dividing plate is positioned at below the oil baffle and is provided with lower liquid hole, and sand sediment pipe top puts in the gas anchor shell to dividing plate, and the gas anchor shell upper is provided with inlet, sand sediment pipe top is provided with inlet opening, returns liquid pipe upper end and is provided with the oil well pump joint.
Characteristics of the present utility model also are:
Inlet is rectangle.
Adjacent oil baffle is staggered to be located at the gas anchor outer casing inner wall and to return on the liquid pipe outer wall.
Lower liquid hole is near the gas anchor outer casing inner wall.
The beneficial effects of the utility model are that a kind of gas anchor of the utility model realizes that by oil baffle is set oil gas efficiently separates, and finally reaches the purpose of volume increase.Simultaneously, shorten the length of gas anchor shell, saved steel, reduced cost, and do not affected effect.
Description of drawings
Fig. 1 is the sectional view of a kind of gas anchor of the utility model.
Among the figure, 1. oil well pump joint, 2. inlet, 3. oil baffle, 4. gas anchor shell, 5. dividing plate, 6. lower liquid hole, 7. inlet opening 8. returns the liquid pipe, 9. sand sediment pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model has improved a kind of gas anchor, as shown in Figure 1, comprise and return liquid pipe 8, return liquid pipe 8 tops cover gas anchor shell 4 is arranged, gas anchor shell 4 length are 50cm, the bottom cover has sand sediment pipe 9, return liquid pipe 8 outer walls and gas anchor shell 4 inwalls are respectively equipped with oil baffle 3, return between liquid pipe 8 outer walls and gas anchor shell 4 inwalls and be provided with dividing plate 5, dividing plate 5 is positioned at below the oil baffle 3 and is provided with lower liquid hole 6, and sand sediment pipe 9 tops put in gas anchor shell 4 to dividing plate 5, and gas anchor shell 4 tops are provided with inlet 2, sand sediment pipe 9 tops are provided with inlet opening 7, return liquid pipe 8 upper ends and are provided with oil well pump joint 1.Inlet 2 is rectangle.Oil baffle 3 only has an end to fix, and two adjacent oil baffles 3 are located at respectively gas anchor shell 4 inwalls and return on liquid pipe 8 outer walls, and are interlaced.Lower liquid hole 6 is near gas anchor shell 4 inwalls.
During oil recovery, from the oil of inlet 2 inflow thin layers, contained gas will be overflowed automatically along inlet 2 and the borehole wall, and process down runs into oil baffle 3, splashes as waterfall, and gas is discharged again in a large number.Oil can flow down by the lower liquid hole 6 on dividing plate afterwards, enters sand sediment pipe 9 from inlet opening 7 again, upwards enters oil well pump by returning liquid pipe 8 at last, thereby makes the oil of down-hole not exploited out smoothly by the interference of gas.
A kind of gas anchor good oil gas separation effect of the utility model helps to improve oil well pump efficient, has increased oil extraction.Simultaneously, existing gas anchor shell is with to return the liquid pipe the same long, and a kind of gas anchor of the utility model to 50cm, has been saved steel with contraction in length, has reduced cost, and has not affected effect.
