Abstract
The utility model discloses a kind of screw pump production technique tubing string, comprising: the sucker rod be linked in sequence from top to bottom and screw pump rotor; Be set in sucker rod outside and to the oil pipe of downward-extension; And the packer, screw pump stator and the anchor that are connected on oil pipe; Wherein, oil pipe is provided with the flow-guiding channel be communicated with outside oil pipe and oil pipe, flow-guiding channel is positioned at the top of packer and screw pump.Screw pump production technique tubing string of the present utility model, by being designed with oil pipe and the passage be directly communicated with outside oil pipe on the oil pipe of packer with screw pump upper portion, fluid is transferred to oil jacket annular space and is given rise to ground in oil pipe, because the area of passage of oil jacket annular space adds several times than the area of passage of oil pipe, greatly reduce the resistance of fluid in lifting process, reduce the power demand to oil pump.
Description
Technical field
The utility model relates to oil extraction in oil field technical field, particularly relates to a kind of screw pump production technique tubing string.
Background technology
In prior art, heavy oil wells is recovered the oil, because viscosity of thickened oil is larger, lifting resistance is very large, in order to prevent the wearing and tearing of sucker rod outer wall and tube inner wall, generally on sucker rod, design multiple centralizer, but because resistance in lifting viscous crude process is very large, need larger power, higher to the power demand of oil pump.
Utility model content
In order to solve the problems of the technologies described above, the utility model discloses a kind of screw pump production technique tubing string, solve the problem that heavy oil wells oil recovery is high to oil pump power demand.
According to an aspect of the present utility model, provide a kind of screw pump production technique tubing string, comprising: the sucker rod be linked in sequence from top to bottom and screw pump stator; Be set in sucker rod outside and to the oil pipe of downward-extension; And the packer, screw pump stator and the anchor that are connected on oil pipe; Oil pipe is provided with the flow-guiding channel be communicated with outside oil pipe and oil pipe, flow-guiding channel is positioned at the top of packer and screw pump.
Alternatively, flow-guiding channel comprises multiple pod apertures.
Alternatively, packer is from sealed packer.
Alternatively, packer is compression packer.
Alternatively, packer is support type packer.
The beneficial effect of embodiment of the present utility model is: a kind of screw pump production technique tubing string, by being designed with oil pipe and the passage be directly communicated with outside oil pipe on the oil pipe of packer with screw pump upper portion, fluid is transferred to oil jacket annular space and is given rise to ground in oil pipe, because the area of passage of oil jacket annular space adds several times than the area of passage of oil pipe, greatly reduce the resistance of fluid in lifting process, reduce the power demand to oil pump.

Detailed description of the invention
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Embodiment
As shown in Figure 1, embodiment of the present utility model discloses a kind of screw pump production technique tubing string, comprising: comprising: face down from ground the sucker rod 1 and screw pump rotor 21 that are linked in sequence; Be set in sucker rod 1 outside and to the oil pipe 3 of downward-extension; And the packer 4, screw pump stator 22 and the anchor 8 that are connected on oil pipe 3; Wherein, screw pump rotor 21 and screw pump stator 22 constitute screw pump 2; Oil pipe 3 is provided with the flow-guiding channel 31 be communicated with outside oil pipe 3 and oil pipe 3, water conservancy diversion leads to the top that 31 roads are positioned at packer 4 and screw pump 2.
In embodiment of the present utility model, as shown in Figure 1, screw pump production technique tubing string of the present utility model also comprises the sleeve pipe 5 being set in oil pipe 3 outside, and form oil jacket annular space 32 between sleeve pipe 5 and oil pipe 3, by the flow-guiding channel 31 having oil pipe 3 and oil jacket annular space 32 to be directly communicated with in packer 4 and screw pump 2 upper design, fluid is transferred to oil jacket annular space 32 and is given rise to ground in oil pipe 3, because the area of passage of oil jacket annular space 32 adds several times than the area of passage of oil pipe 3, greatly reduce the resistance of fluid in lifting process, reduce the power demand to oil pump.
Alternatively, as shown in Figure 1, flow-guiding channel 32 comprises multiple pod apertures, offers multiple pod apertures and the fluid major part in oil pipe 3 can be made to flow in oil jacket annular space 32 carry out lifting, shared the pressure of oil pipe 3.
Alternatively, as shown in Figure 1, packer 4 can adopt from sealed packer, support type packer, compression packer or other forms of packer, those skilled in the art should be understood that concrete installation site and the method for multi-form packer, no longer be described in detail at this, the present embodiment is for from sealed packer, and it is outside that packer 4 is set in oil pipe 3, and fit with oil pipe 3 outer wall.
Alternatively, as shown in Figure 1, this screw pump production technique tubing string also comprises: the centralizer 9 being sheathed on sucker rod 1 outside, significantly reduces the wearing and tearing caused when sucker rod 1 moves up and down in oil pipe 3; Be positioned at the stop 7 below screw pump 2, and be sheathed on the anchor 8 of oil pipe 3 outside below described screw pump 2, those skilled in the art should understand that the concrete function of stop 7 and anchor 8, be no longer described in detail at this; Wherein, oil pipe 3 bottom is provided with feed pathway 33, under the effect of screw pump 2, fluid in oil well enters oil pipe 3 from feed pathway 33 and upwards carries, after arriving flow-guiding channel 31 place, flow into oil jacket annular space 32 by flow-guiding channel 31 and upwards carry, greatly reducing the resistance of fluid in lifting process.
Above-described is preferred embodiment of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
