Technical field
The utility model relates to a kind of oil development oil production technology lifting tubing string, especially relates to the two water jet pump lifting tubing strings of a kind of heavy oil wells.
Background technology
In the recovery process of heavy crude reservoir, usually can be large because of reducing crude oil viscosity, make crude oil enter pump difficulty, can not smoothly crude oil be given rise to ground.For the exploitation of heavy oil wells, mainly adopt the technologies such as heating sucker rod, chemistry are handled up, steam soak, but because its energy consumption is high, cost is difficult to greatly large-area applications.In recent years, hydraulic pump fluid-discharge technology technology is applied to thickened oil recovery, has played good effect, is also a main technique technology of current heavy crude reservoir exploitation.But conventional water jet pump is in thickened oil recovery, just liquid more than hydraulic pump is carried out to viscosity reduction, fine for deep-well effect, and for the more shallow oil reservoir of the degree of depth, the following crude oil between from oil reservoir to hydraulic pump of hydraulic pump is difficult to enter hydraulic pump, the following crude oil of hydraulic pump can not be come up by suction fully, be difficult to reach thickened oil recovery object.
Utility model content
In order to overcome existing production technique, can not meet the deficiency of shallow layer thick oil exploitation needs, the utility model provides a kind of heavy oil wells two water jet pump lifting tubing strings.
The utility model solves the technical scheme that its technical problem adopts: the two water jet pump lifting tubing strings of heavy oil wells comprise oil pipe, packer, water jet pump, tail pipe, inner tube, in pit shaft, be installed with sleeve pipe, lifting tubing string is positioned at sleeve pipe, oil pipe I, lifting water jet pump, oil pipe II, tail pipe, water jet pump are from top to bottom fixedly connected sequentially, and water jet pump is positioned at oil reservoir; In oil pipe II, packer is installed, packer is positioned at the top of oil reservoir.
Between lifting water jet pump lower end liquid outlet and water jet pump upper end inlet, inner tube is installed, inner tube is positioned at oil pipe II.
On the tail pipe of packer below, there is radial flow of liquid hole I to discharge for production fluid; In the oil pipe II of packer top, having in radial flow of liquid hole II, inner tube has radial flow of liquid hole III to discharge for the mixed liquor of production fluid and power fluid.
The pump core of lifting water jet pump has a split channel, and binary channels flows through for power fluid.Water jet pump is adjustable flow water jet pump.
The beneficial effects of the utility model are, rational in infrastructure, solved viscous crude poor fluidity, have entered the problems such as pump difficulty, can ask at short notice standard demand perfection oily well capacity and parameters, practical.
Accompanying drawing explanation
Fig. 1 is the two water jet pump lift tube rod structure schematic diagrames of the utility model heavy oil wells.
In figure: 1. oil pipe I, 2. lifting water jet pump, 3. packer, 4. inner tube, 5. tail pipe, 6. water jet pump, 7. power fluid, 8 mixed liquors, 9. production fluid, 10. minute flow liquid, 11. oil reservoirs, 12. sleeve pipes, 13. oil pipe II, 14. radial flow of liquid hole I, 15. radial flow of liquid hole II, 16. radial flow of liquid hole III.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.But those skilled in the art should know, the utility model is not limited to the listed specific embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
Referring to accompanying drawing 1.The two water jet pump lifting tubing strings of the utility model heavy oil wells are arranged in the hard-wired sleeve pipe 12 of pit shaft.
Oil pipe I 1, lifting water jet pump 2, oil pipe II 13, tail pipe 5, the water jet pump 6 of the two water jet pump lifting tubing strings of the utility model heavy oil wells are from top to bottom fixedly connected sequentially, and water jet pump 6 is positioned at oil reservoir 11.Packer 3 is installed in oil pipe II 13, and packer 3 is positioned at the top of oil reservoir 11.The length of oil pipe I 1, oil pipe II 13 is determined according to oil well depth.
Between lifting water jet pump 2 lower end liquid outlets and water jet pump 6 upper end inlets, inner tube 4 is installed, inner tube 4 is positioned at oil pipe II 13.The pump core of lifting water jet pump 2 has a split channel, and binary channels flows through for power fluid 7.Water jet pump 6 can be selected adjustable flow water jet pump.
On packer 3 below tail pipes 5, there is radial flow of liquid hole I 14 to discharge for production fluid 9; In the oil pipe II 13 of packer 3 tops, having in radial flow of liquid hole II 15, inner tube 4 has radial flow of liquid hole III 16 to discharge for production fluid 9 and the mixed liquor 8 of power fluid 7.
The operating principle of the two water jet pump lifting tubing strings of the utility model heavy oil wells is, from well head by power fluid 7 injection strings, when power fluid 7 process lifting water jet pump 2, throttling action due to nozzle in pump, power fluid 7 is converted to velocity head by head, pressure sharply declines, at nozzle, form low-pressure area around, oil reservoir production fluid 11 is under the effect of stratum energy, through tail pipe 5, enter the interior low-pressure area that flows to of lifting water jet pump 2, after mixing with the high-speed jet of jet expansion, enter the trunnion supercharging of slowing down gradually, at trunnion place mixed liquor 8, by kinetic energy, be converted to potential energy, mixed liquor 8 is given rise to ground along oil pipe I 1 and the annular space of sleeve pipe 12.
Simultaneously, at lifting water jet pump, 2 pump core places are designed with a split channel (binary channels is crossed fluid), sub-fraction in power fluid 7 can be divided flow liquid 10 be incorporated into adjustable flow water jet pump below 6, this part divides flow liquid 10 to mix through the liquid of adjustable flow water jet pumps 6 and oil reservoir 11, reduce viscosity of thickened oil, increase liquid fluidity, production fluid 9 after viscosity reduction enters lifting water jet pump 2 low-pressure areas by the space between tail pipe 5 and inner tube 4 fast, then be lifted to ground, reach the object of real reducing thick oil viscosity.
The two water jet pump lifting tubing strings of application the utility model heavy oil wells carry out thickened oil recovery, have following characteristics:
1, thinner or heat power liquid can be introduced below water jet pump completely, be compared with conventional water jet pump viscous crude discharge opeing technology, viscosity reducing effect is obvious, has solved the problem that crude oil enters pump difficulty, has really realized viscous crude discharge opeing;
2, pressure gauge is lowered into tail pipe end, truly measures oil reservoir stream and press;
3, part power fluid can be introduced to oil reservoir position, therefore, for the oil well necessarily shaking out, there is sediment outflow effect;
4, be applicable to the superelevation thickened oil recovery of viscosity of crude >=100000mPa.s.
It should be noted that above-described embodiment is example and unrestricted the utility model, those skilled in the art can design a lot of alternate embodiments and not depart from the claim scope of this patent.
