In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of skid-mounted wellhead pressure release re-injection device, comprise water tank, booster pump and water pipe, also comprise skid water filling device and purifier, described skid water filling device comprises water injecting pump and motor, described water tank utilizes water pipe to be connected on purifier and booster pump, and booster pump is connected on skid water filling device.
Described purifier comprises basket filter, reducing valve group, sponge filter, fabric filter, and described reducing valve group is connected on basket filter and sponge filter, and fabric filter is connected on sponge filter.
It is filter medium that described sponge filter adopts sponge filtrate, and requires to adopt different filtrate combinations according to different water treatments.
In described fabric filter, adopting modified fiber ball is filter medium.
Sponge filter in described purifier and fabric filter tank body all adopt Q235B steel making.
The inwall of described sponge filter and fabric filter adopts derusting by sandblasting to carry out anticorrosion and rust cleaning.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Integrated skid water filling device of the present utility model, adopts skid-mounted type modularized design to shorten the construction period water injecting pump, motor and control device, saves land used, easy for installation, and can need resettlement flexibly according to oil field development.Again improved filter for purifying water, using sponge filtrate is filter medium, according to different water treatments, require to adopt different filtrate combinations, during filtration, oil-polluted water flows through filtering layer from top to bottom, oil and suspension are blocked, after backwash, remove suspension and part oil, further adopt modified fiber ball filter core, Fiber Materials surface obviously strengthens oil and mechanical foreign material adsorption capacity, filtrate is difficult for contaminated and backwash and regeneration convenient, filtrate adopts gas, water backwash, guarantee that filtrate has reasonable to the design of backwash structure, to guarantee filtrate mixed layer when the backwash, filtration purifying water effect is good.
Accompanying drawing explanation
The expressed content of each accompanying drawing of this manual and the mark in figure are made to brief description below:
Fig. 1 is structural representation of the present utility model;
Mark in above-mentioned figure is: 1, purifier; 11, basket filter; 12, reducing valve group; 13, sponge filter; 14, fabric filter; 2, valve; 3, water tank; 4, booster pump; 5, skid water filling device; 51, water injecting pump; 52, motor; 6, water pipe.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operating principle etc.
As shown in Figure 1, a whole set of water filling device is comprised of purifier 1, valve 2, water tank 3, pressure charging valve 4, skid water filling device 5 and water pipe 6 etc., the whole flow process of water filling is " basket filter 11 → reducing valve group 12 → purifier 1(sponge filter 13+ fabric filter 14) → water tank 3 → booster pump 4 → water injecting pump 51 → water injection well ", and water to be processed passes through said apparatus successively.
Large particle foreign material in the main removal water of basket filter 11 are the pre-processing device of follow-up filtration; Reducing valve group 12 is that flat gate valve and multistage high-pressure pressure-reducing valve group form, and well head discharge pressure is reduced to filter plant design and operation pressure, guarantees equipment safety operation.
Sponge filter 13, for sponge filter is the strainer that a kind of clear water and sewage can be used, is suitable for oilfield sewage fine filtering.It is filter medium that this strainer adopts special sponge filtrate, according to different water treatments, requires to adopt different filtrate combinations, and during filtration, oil-polluted water flows through filtering layer from top to bottom, and oil and suspension are blocked, and remove suspension and part oil after backwash.Filtrate adopts gas, water backwash, guarantees that filtrate has the design of backwash structure is wanted rationally, to guarantee filtrate mixed layer when the backwash.During filtration, current are from top to bottom by filtering tank and filtrate, and pollutant holding capability is large, and filtration resistance is little.When filtrate pollutes to a certain degree while surpassing filtrate pollutant holding capability, will carry out backwash, during backwash, the reverse flow from bottom to top of current and air-flow is through filter, and when backwash, upper strata filtrate constantly overturns with current and air-flow, carries out backwash, and dirt departs from from filtrate; Treat that backwash is complete, equipment enters filtration condition automatically, enters the next work period.The selected filtrate of sponge filtering material filter has stronger adsorption capacity, for filtering oily sewage, to oil and the clearance of suspension up to 80%, the high-quality filtrate of selecting has the features such as filtering velocity is high, retaining power is strong, life cycle is long, mechanical strength is high, corrosion-resistant, chemical stability is good, this strainer is applicable to the fine filtering of oil-contaminated water of oil field, is also applicable to the processing of other industrial wastewaters.
Fabric filter 14 adopts new modified fiber ball filter, modified fiber ball be by fibrous nodules after new chemical formulation is done essential modification, material surface obviously strengthens oil and mechanical foreign material adsorption capacity, and filtrate is difficult for contaminated and backwash and regeneration convenient.Simultaneously it also to have modified fibre filament diameter very thin, specific area is large, after stack, filtering layer hole is little, all better than other filtrate to the interception function of suspension.Modified fibre is heavy and viscous oil not than general fibre, and at the bottom of sinking to tank during filtration, upper Panasonic is tight, filtering layer pore structure is good, and during operation, filtering layer hole dwindles gradually along water (flow) direction, has formed the more satisfactory up big and down small distribution of filtering layer hole, therefore retaining power is strong, good filtration effect.
Sponge filter 13 in purifier 1 and the tank body of fabric filter 14 all adopt Q235B steel making, and Q235B steel has good withstand voltage and corrosion resistance, and inner tank wall adopts derusting by sandblasting to carry out anticorrosion and rust cleaning.Meanwhile, the pipeline junction in whole pressure release re-injection device has all been carried out to anticorrosion and antiseepage processing, valve 2 is all selected anti-obstruction, lining tetrafluoro butterfly valve and stainless steel plug valve, has the features such as quality is good, long service life.
Skid water filling device 5 comprises water injecting pump 51, motor 52 and some pressure detecting instruments and electric equipment control instrument, and being made into skid pattern is modularization, is conducive to like this equipment installation in field and the maintenance of later stage faulty equipment.
Water becomes the pressure that purifier 1 needs after entering reducing valve group 12, after the filtration of purifier 1, reach the water quality of waterflooding requirement, enter in water tank 3 and store, water tank 3 is connected with booster pump 4 by water pipe 6, water increases hydraulic pressure under the effect of booster pump 4, water under high pressure injects water injecting pump 51, and last water under high pressure is injected in oil well.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
