Abstract
An oil well separate production pump is characterized in that an upper working barrel 2 with a larger inner diameter is combined with a lower working barrel 7, an upper plunger 3, a lower plunger 5 and the like are installed in the upper working barrel 2, the upper plunger 3 with a larger outer diameter is combined with the lower plunger 5, and an upper oil inlet valve 10 is further installed on the outer wall of the upper working barrel 2. The utility model has the advantages of simple structure and reasonable design, low in production cost owing to adopted double pump combination and single tube oil transportation mode, therefore have that the site operation is simple and convenient, work safe and reliable, can extensively be used for the oil recovery operation of layering of all kinds of pumping wells.
Description
Technical field: the utility model relates to a kind of oil field downhole hardware, especially for a kind of oil well separate extracting pump of pumping well.
Technical background: before the utility model, general oil field is that the two-tube and middle packing mode of double pump is adopted in oil production by layer more, though have certain oil increasing effect, by its complex structure, construction inconvenience, many, the poor reliability of accident is difficult to apply in the using process.
Summary of the invention: the purpose of this utility model is for the oil field oil production by layer provides a kind of oil well separate extracting pump, should have single pump housing and single tube oil transportation structure, reliable operation, is convenient to the site operation operation, but characteristics such as wide popularization and application and oil increasing effect be good.
The purpose of this utility model realizes by following measure: a kind of oil well separate extracting pump, be by upper plug, lower plunger, last working barrel, following working barrel, last oil-feed valve, go up fuel-displaced valve, following oil-feed valve, fuel-displaced valve and standing valve are formed down, it is characterized in that last working barrel that internal diameter is bigger and following bottom install and fix the following working barrel combination of valve, its inner correspondence is equipped with upper plug and lower plunger etc., and have fuel-displaced valve, the bigger upper plug of external diameter with below have the oil-feed valve and the lower plunger combination of fuel-displaced valve down down, also be equipped with on the last working barrel outer wall be communicated with its inner chamber on the oil-feed valve.
The utility model is simple in structure, reasonable in design, cost of production is low, owing to adopted double pump combination and single tube oil transportation mode, thereby it is easy, safe and reliable to have a site operation, can be widely used in the oil production by layer operation of all kinds of pumping wells.
Description of drawings: Fig. 1 is the structural representation of oil well separate extracting pump.
The oil well separate extracting pump by upper plug 3, lower plunger 5, go up working barrel 2, down working barrel 7, go up oil-feed valve 10, go up fuel-displaced valve 9, down oil-feed valve 6, fuel-displaced valve 4 and standing valve 8 are formed down.
Embodiment: it is following working barrel 7 combinations that bigger last working barrel of internal diameter 2 and following bottom install and fix valve 8 that the oil well separate extracting pump constitutes, its inner correspondence is equipped with upper plug 3 and lower plunger 5 etc., and have the bigger upper plug of fuel-displaced valve 9, external diameter 3 with below have the oil-feed valve 6 and lower plunger 5 combinations of fuel-displaced valve 4 down down, also be equipped with on last working barrel 2 outer walls be communicated with its inner chamber on oil-feed valve 10.When the oil well separate extracting pump uses should be earlier with it with (the having packet) tubing string that can realize oil production by layer and the beam hanger post is connected and down to the precalculated position, down-hole, start pumping unit then and do upper and lower to-and-fro motion by sucker rod 1 drive upper plug 3 and lower plunger 5.At this moment, well interior (double-deck branch is adopted) lower floor's output liquid gets final product (through tubing string) by standing valve 8, following oil-feed valve 6, following fuel-displaced valve 4 and lower plunger 5, discharges from the liquid outlet of upper plug 3 upper ends; Upper strata output liquid then can enter in its chamber by the last oil-feed valve 10 on last working barrel 2 outer walls, again through last fuel-displaced valve 9, discharges from upper plug 3 upper end liquid outlets, thereby has realized that double-deck branch is adopted, the single tube oil transportation.
