Abstract
The invention relates to an oil-water well stratigraphic reservoir water-injection decontamination filtering self-cleaning device. With the device, an execution mechanism can be operated such that back-wash self-cleaning can be performed. The device comprises an upper flange valve cover with the execution mechanism, and a housing cylinder body with a flange on the upper part and a sealing head on the lower part. An inner cylinder body with a Trumpet-opening copper-powder-particle-sintered filtering sieve on the upper part is arranged inside the housing cylinder body. The housing cylinder body is respectively provided with a water inlet pipe with a valve, a water outlet pipe with a valve, and a sewage discharge pipe with a valve. During a normal operation process, the execution mechanism valve rod seal is elevated; inlet water flows through the inner cylinder body with the copper powder particle sintered filtering sieve, and impurities are retained on the tapered surface of the trumpet opening, such that purposes of filtering and sterilizing are achieved. During a self-cleaning process, the execution mechanism valve rod seal is sealed with a sealing groove of the inner cylinder body; water flows through the trumpet opening tapered surface, and back-washes the wall surface of the inner cylinder body; and a sewage-discharge valve is opened, such that sewage-discharge back-wash is carried out. With the device provided by the invention, sterilization, filtration and back-wash self-cleaning can be realized with simple operations; and an oil-water well stratigraphic reservoir water-injection decontamination filtering problem can be effectively solved.
Description
Technical field
The present invention is that cleaning apparatus for self is filtered in a kind of oil and water well stratigraphic-type reservoir water filling scrubbing.Especially can operate topworks and carry out the self-cleaning scrubbing filtration unit of back flushing.
Background technology
Along with increasing at stratum produced quantity of oil, water flooding recovery is also Oilfield using oil production method the most widely, must supplement producing energy by water filling improves oil displacement efficiency and stablizes well flow capacity, because injected water is the water of crude oil extraction after processed, in being transported to well head injection process, there is bacterium amount reproduction, sulphate reducing bacteria (SRB) particularly, the Fe2+ that the product S 2-of its reaction produces with Corrosive is combined and is generated FeS, suspended substance significantly increases, in injected water and contain a small amount of sulfide and other indissoluble things, not only tube wall causes corrosion, and can produce dirt or the sludge that comprises Iron sulfuret on tube wall, these solid particulates, mechanical impurity, dirts etc. directly inject oil reservoir, cause oil reservoir duct to stop up, fully do not supplement formation oil KURA energy, had a strong impact on field produces exploitation petroleum production.Existing strainer cannot be realized timely self-cleaning function.
Summary of the invention
The object of the invention is to, solve above-mentioned existing existing problem, provide a kind of oil and water well stratigraphic-type reservoir water filling scrubbing to filter back flushing self-stripping unit.
The present invention is achieved in that this device You Dai topworks upper flange valve gap and upper flanged, the lower casing cylinder with end socket and inner upper band hydraucone copper powder particles sintering filter sieve cylindrical shell form.Be bolted topworks and upper flange valve gap, the valve rod end of topworks connects copper seal plug; Upper flange valve gap one side is provided with by bearing pin and is connected with shell flange, and upper flange valve gap is connected with casing cylinder flange by circumference uniform distribution bolt; Casing cylinder top and bottom sidewall is respectively equipped with water-in pipe, the water outlet pipe with valve, and end socket center is provided with band valve sewage draining exit pipe; In casing cylinder, centering adjustment longitudinal center line is provided with band hydraucone copper powder particles sintering screen inner barrel, its hydraucone screen bigger diameter end is connected in water-in pipe lower sideline position with casing cylinder inwall, its screen inner barrel lower end is connected with casing cylinder end socket inwall, form copper powder particles sintering screen inner barrel EL, be able to the object that degerming scrubbing is filtered.
Feature of the present invention is, utilize copper powder particles sintering screen millipore filtration characteristic and cupric ion degerming thereof, solve physics degerming and solid particulate in the injecting process, the contaminant filter problems such as dirt, surperficial crown_interception by copper powder particles sintering screen inner barrel is realized sterilizing, filter and the clean screen inner barrel dirt of back flushing, guarantee to inject oil reservoir water quality reaching standard, indices can reach A2 level index in SY/T 5329-1994 < < Clastic Stratum of Country Rocks reservoir water water quality fertilizer index > >.This device simple operations topworks just can realize back flushing self-stip, improves injection water quality, and free removal is cleaned and changed, effectively solves dismounting filtration unit stop production to overhaul cleaning work amount associated cost and secondary pollution environmental protection problem.
