Abstract
The utility model relates to an oil recovery device, in particular to a novel water-injected oil well oil recovery device. The technical scheme is that the novel water-injected oil well oil recovery device comprises a sleeve, a pump barrel, movable water distributors, packers, an injection pump, a screening pipe, a plug and a circulating valve, wherein the pump barrel is fixed inside the sleeve, three groups of movable water distributors are arranged on the pump barrel, the packers are arranged among the movable water distributors, the pump barrel is connected with the injection pump, the bottom of the injection pump is connected with the screening pipe and the plug, and the circulating valve is arranged in the injection pump. The novel water-injected oil well oil recovery device has the advantages of being simple in structure, easy to assemble, high in reliability and capable of being used in a plunger type water injection pump for water-injected oil well oil recovery, effectively improving the oil recovery efficiency and reducing the production cost.
Description
One, technical field
The utility model relates to a kind of extracting device of oil, particularly a kind of novel water injection well extracting device of oil.
Two, background technology
Exploitation gradually along with oil field, expose many problems, the most of oil field of China is all heterogeneous body multiple zone sandstone oil reservoir, all kinds of oil reservoirs have very large otherness in interlayer, plane, by a minute different straticulate exploration, every mouthful of well still has several or tens substratums to exploit, and the permeability between each layer still exists larger difference, and these differences have a significant impact waterflooding development effect.Have in oil field physical difference, layer contradiction, interlayer contradiction very outstanding, the individual layer in the injecting process advance by leaps and bounds and tonguing phenomenon fairly obvious, cause injected water to advance inhomogeneous, increased the exploitation difficulty of oil well, improved field produces cost.
Three, summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of novel water injection well extracting device of oil is provided.
Its technical scheme is: comprise sleeve pipe, pump barrel, movable distributor, packer, water jet pump, screen casing, plug, circulating valve, inside pipe casing is pump barrel fixedly, described pump barrel is provided with three groups of movable distributors, between described movable distributor, be provided with packer, pump barrel connects water jet pump, the bottom of described water jet pump connects screen casing and plug, in described water jet pump, is provided with circulating valve.
The beneficial effects of the utility model are: simple in structure, assembling easily, reliability is high, can be used for, in plunger type water injection pump that flushing recovers the oil, effectively having improved oil recovery efficiency, have reduced cost of production.
Four, accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: sleeve pipe 1, pump barrel 2, movable distributor 3, packer 4, water jet pump 5, screen casing 6, plug 7, circulating valve 8.
Five, the specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises sleeve pipe 1, pump barrel 2, movable distributor 3, packer 4, water jet pump 5, screen casing 6, plug 7, circulating valve 8, the inner fixedly pump barrel 2 of sleeve pipe 1, described pump barrel 2 is provided with three groups of movable distributors 3, between described movable distributor 3, be provided with packer 4, pump barrel 3 connects water jet pump 5, the bottom of described water jet pump 5 connects screen casing 6 and plug 7, in described water jet pump 5, is provided with circulating valve 8.
Simple in structure, assembling easily, reliability is high, can be used for, in plunger type water injection pump that flushing recovers the oil, effectively having improved oil recovery efficiency, reduced cost of production.
