Abstract
Provided is a high efficiency gas anchor for a screw pump. The high efficiency gas anchor for the screw pump essentially solves a problem that big resistance is stressed on gas upgoing of the existing gas anchor after gas-liquid separation. The high efficiency gas anchor for the screw pump is characterized in that an outer pipe (2) is externally connected between an upper connector (1) and a lower connector (6), a core pipe (3) is connected with the lower end of the upper connector (1), a collecting sleeve (4) is fixedly connected with the outside of the upper portion of the core pipe (3), and a sealing plug (7) is arranged between an upper end head of the collecting sleeve (4) and the core pipe (3). An air outlet (8) is arranged on the lateral wall of the core pipe (3) arranged at the lower end of the sealing plug (7), spiral blades (5) are fixed outside the collecting sleeve (4) and outside the core pipe (3), a liquid outlet (9) communicated with the inside of the upper connector (1) and the inside of the outer pipe (2) is arranged on the upper connector (1) in the axial direction, and an exhaust hole (10) communicated with the inside of the core pipe (3) and the inside of a sleeve tube is arranged on the upper connector (1) in the radial direction. The high efficiency gas anchor for the screw pump is not only excellent in gas removing, but also smooth in the gas upgoing after the gas-liquid separation.
Description
Technical field:
The utility model relates to the efficient gas anchor of oil recovery field, oil field screw pump used depassing unit, especially screw pump.
Background technology:
In oil recovery field, oil field,, gas anchor is installed on screw pump for preventing that gas is pumped in the screw pump in the well.Spiral gas anchor is mainly adopted in screw bolt well degasification at present.In actual use, spiral gas anchor gas-liquid separation effect is good, but the up suffered resistance of gas is big after the gas-liquid separation, influences the screw pump degassing effect.
The utility model content:
In order to solve the big problem of the up suffered resistance of gas after the existing gas anchor gas-liquid separation.The utility model provides a kind of screw pump efficient gas anchor.Not only degassing effect is good with efficient gas anchor for this screw pump, and gas is up smooth and easy after the gas-liquid separation.
The technical solution of the utility model is: this screw pump comprises top connection, outer tube, core pipe, collects cover, helical blade and lower contact with efficient gas anchor.Outer between top connection and the lower contact by the outer tube that has been threaded, the top connection lower end is by being threaded and its core pipe that does not communicate, core pipe top external fixation is connected with collects cover, collection puts to be provided with between termination and the core pipe to seal and blocks up, on the core pipe sidewall of the stifled lower end of sealing venthole is arranged, collect cover and core pipe external fixation helical blade is arranged, fluid hole is axially arranged in the top connection, fluid hole respectively with top connection in and outer tube in communicate, steam vent is radially arranged in the top connection, steam vent respectively with the core pipe in and sleeve pipe in communicate.
Collection cover in the such scheme and core pipe external fixation have two bar helical blades.
The utlity model has following beneficial effect: this screw pump is collected cover with efficient gas anchor because employing is connected with at core pipe top external fixation, collection puts to be provided with between termination and the core pipe to seal and blocks up, on the core pipe sidewall of the stifled lower end of sealing venthole is arranged, collect cover and core pipe external fixation helical blade is arranged, fluid hole is axially arranged in the top connection, fluid hole respectively with top connection in and outer tube in communicate, steam vent is radially arranged in the top connection, steam vent respectively with the core pipe in and sleeve pipe in communicate optimize structure.Utilize to collect cover and collect gas, be discharged in the sleeve pipe gas is smooth and easy by venthole, core pipe and steam vent again, and then reduce the up suffered resistance of gas, make gas flow smooth and easy.Form independently that gas data feedback channel and outer tube, collection cover and fluid hole form independent well liquid data feedback channel owing to adopt to collect cover and core pipe, venthole and steam vent, 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 degassing effect is good with efficient gas anchor for this screw pump 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, the 2-outer tube, 3-core pipe, 4-collects cover, the 5-helical blade, the 6-lower contact, the 7-sealing is stifled, 8-venthole, 9-fluid hole, 10-steam vent.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this screw pump comprises top connection 1, outer tube 2, core pipe 3, collects cover 4, helical blade 5 and lower contact 6 with efficient gas anchor.Outer between top connection 1 and the lower contact 6 by the outer tube 2 that has been threaded, top connection 1 lower end is by being threaded and its core pipe 3 that does not communicate, core pipe 3 upper ends do not communicate with top connection 1, core pipe 3 top external fixation are connected with collects cover 4, collect and be provided with sealing stifled 7 between cover 4 upper ends and the core pipe 3, on core pipe 3 sidewalls of stifled 7 lower ends of sealing venthole 8 is arranged, collect cover 4 and core pipe 3 external fixation wall scroll or many helical blades 5 are arranged, fluid hole 9 is axially arranged in the top connection 1, fluid hole 9 communicates with top connection 1 interior reaching in the outer tube 2 respectively, steam vent 10 is radially arranged in the top connection 1, and steam vent 10 communicates with core pipe 3 interior reaching in the sleeve pipe respectively.
During actual the use:
This screw pump is connected the screw pump lower end with efficient gas anchor, in the lower going-into-well, can normally uses.Behind the starting screw pump, under the effect of the pumping power of screw pump, well liquid enters from lower contact 6, along outer tube 2, core pipe 3, helical blade 5 rotations are quickened up, 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, centrifugal force is little, bubble can be up along core pipe 3 outer walls, when gas be up to collect in the cover 4 after, overlap 4 along collecting, helical blade 5, the back is up in the screw type space that core pipe 2 is formed, enter core pipe inside by venthole 8 collecting cover 4 tops, up and enter the oil jacket annular space by the core pipe by steam vent 10.Well liquid enters screw pump after the spiral space of collecting cover 4, helical blade 5 and outer tube 2 compositions goes upward to top connection 1, 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 screw pump has been obtained remarkable result with efficient gas anchor by The field.
