Description
Technical field
The present invention relates to a kind of high-inclination horizontal well oil pump.
Background technique
Oil well pump is the oil production equipment that extensively adopt in the oil field, and the SAGD oil well pump is condensing of high temperature high-inclination horizontal well oil pump.
Late nineteen eighties begins the drilling horizontal well abroad, designs and manufactures conventional large-scale SAGD oil well pump complete equipment import price at present abroad and is about 300,000 RMB.China horizontal well occurs at the early 1990s, and the SAGD oil well pump maximum of comparative maturity has a daily output of 200m3 at present.Along with the raising of horizontal well technology, the technology of SAGD is day by day ripe, and existing horizontal well oil pump can not satisfy the requirement of field output.
Summary of the invention
The purpose of this invention is to provide a kind of high-inclination horizontal well oil pump.
The objective of the invention is to be achieved through the following technical solutions: comprise large-diameter extraction oil pump 3, the ring-like valve oil-well pump 50 of minor diameter, little oil pipe 1, Big Inch 2, oil pipe fixture 6, sleeve pipe 9, well head 10, sucker rod 4, pumping unit 15.Sleeve pipe 9, well head 10, sucker rod 4, pumping unit 15 belong to the necessary equipment of oil well, do not belong to content of the present invention.Big Inch 2 is arranged in the sleeve pipe 9.By oil pipe fixture 6, Big Inch 2 roof anchorage are at little oil pipe 1 middle part.Large-diameter extraction oil pump 3 hands insert sleeve pipe 9 and are fixed on Big Inch 2 bottoms, and the ring-like valve oil pumping of minor diameter valve oil-well pump 50 is fixed on little oil pipe 1 bottom.Little oil pipe 1 inserts in the Big Inch 2 from the oil pipe fixture 6 at Big Inch 2 tops, and extension is connected with the top of the ring-like valve oil-well pump 50 of minor diameter downwards, in minor diameter ring valve valve oil-well pump 50, the lower end of sucker rod 4 is connected with the plunger head of the ring-like valve oil-well pump 50 of minor diameter.The bottom of ring-like valve oil-well pump 50 plungers of minor diameter is fixed with pony rod 4, and pony rod 4 passes the ring-like valve oil-well pump of minor diameter 50 bottoms, and pony rod 4 lower ends are connected with the plunger head of large-diameter extraction oil pump 3.On the oil pipe fixture 6 through hole is arranged.The effect of through hole is after the liquid of major diameter oil pumping 3 extractions is full of Big Inch 2, may flow back to first liquid level, 7 places of sleeve pipe 9 by through hole.
Advantage and effect that the present invention had are:
Utilize large-diameter extraction oil pump pumping liquid, enter the ring-like space between the big little oil pipe after big pump boosts liquid, form second liquid level in this ring-like space, the submergence that this liquid level forms is more a lot of greatly than the submergence that is formed naturally by the luxuriant pressure of oil.Little pump intake is under this big submergence, so the full level height of pump, by the minor diameter oil well pump liquid is given rise to ground.Sucker rod and pumping unit can bear little pump in last power when carrying pump plunger.Thus, can be implemented in the purpose of the luxuriant raising lifting rate of low submergence oil.
