Abstract
An oil production long-suction method is a method in oil production and a method, which is different from halfway oil absorption of an oil-well pump and can fast enable the oil-well pump to omnipotently absorb the oil in a vertical stroke by an isolation valve. The pumping efficiency can be doubled and 50% of energy source can be saved.
Description
One, technical field: application of the present invention relates to a kind of method of petroleum production.
Two, background technique: now in petroleum production, a large amount of rod pumping pumps that use, the working state of oil well pump is the half way oil suction; Oil suction when promptly promoting, the oil extraction during whereabouts, this kind structure not science requires gram to carve to oil recovery cooperation factor; Make the oil well pump quick abrasion, average life was less than 450 days.Manufacturing efficiency is low, and cost is high.
Three, summary of the invention: optimize structure, on oil well pump, increase, build up speed at a distance from valve; Become a pump chamber and be two pump chambers; Make oil well pump have pump chamber to keep negative pressure all the time, realize plunger, thereby realize enhancing productivity one times, energy-conservation 50% purpose in the fall time oil suction.
Four, Figure of description: the numeral among the figure is expressed as following content respectively:
1, pump anus 2, sucker rod 3, plunger 4, fixing all youngsters
5, travelling valve 6, at a distance from the big ring of valve 7, at a distance from the little ring of valve 8, go up pump chamber
Five, mode of execution
1, the work of oil well pump is exactly to-and-fro motion one on the other.Apneusis is exactly oil suction when realizing the plunger whereabouts.The separated valve of being made up of small one and large one two annulus as shown in Figure 1 is installed in the top of oil well pump, encircles 6 greatly and is stuck on the pumping cylinder, and little ring 7 is slidingly matched with sucker rod 2 on big ring.When plunger 3 falls; Separated valve by small one and large one two annulus 6,7 are formed cuts out; Oil in the oil pipe can not be dirty, and pressure can not descend pass, 8 one-tenth negative pressure oil suctions of last pump chamber of plunger 3 and separated 6 formation of valve; All youngsters 5 that moves about open automatically, and oil is through fixing all youngster 4` lower oil cavities. and all youngsters 5 that moves about suck upper oil cavitie 8 and have realized the down stroke oil suction.Oil pump was filled and carries out fast lifting when plunger 3 was fallen the end, separately oil was discharged at a distance from valve 7 effect of being stressed.Lower oil cavitie oil suction between plunger 3 and fixing all youngster 4`, plunger 3 are in the lifting time, and it is half that the oil that lower oil cavitie sucks should be.Oil suction when falling for plunger 3 produces the oil suction space, has so just realized the purpose of plunger in the fall time oil suction.
Six: Figure of abstract: be exactly Figure of description.
Claims (1)
1. one kind increases by one at a distance from valve on oil well pump, forms upper and lower formation two oil pockets by big ring 6 with little ring 7 at a distance from valve; Lower oil cavitie oil suction when the plunger fast lifting; Upper oil cavitie is characterized in that fast lifting at the oil production long extraction method of fall time oil suction, realizes the oil suction of plunger fall time.
