Abstract
The utility model relates to an ultrahigh-pressure water injection wellhead filter, which is simple in structure and convenient to use and capable of filtering injected water effectively. The filter comprises a pressure bearing steel cylinder, a water inlet is arranged on the side of the pressure bearing steel cylinder, a water outlet is arranged at the bottom of the pressure bearing steel cylinder, an anticorrosion metal lining pipe is arranged inside the pressure bearing steel cylinder, and a filter element is arranged inside the metal lining pipe.
Description
Technical field
The utility model relates to a kind of super-pressure water injection well filter.
Background technology
Overwhelming majority block in oil field has entered the high moisture productive life at present, must filter when water filling, the pollution of impurity in the anti-sealing.But present used filter, structure are comparatively complicated, successfully do, and filter effect is not good.
The utility model content
The purpose of this utility model provides a kind of simple in structure, easy to use exactly for addressing the above problem, can be effectively to injecting the super-pressure water injection well filter that water quality is filtered.
For achieving the above object, the utility model adopts following technical scheme:
A kind of super-pressure water injection well filter, it comprises a pressure-bearing steel cylinders, and the sidepiece of pressure-bearing steel cylinders is provided with water inlet, and the bottom is provided with delivery port, then is provided with the corrosion resistant metal bushing pipe in pressure-bearing steel cylinders inside, is provided with filter core in metal liner.
Described filter core is the PEC sintered filter core.
The utility model is at oilfield injection water matter characteristic and requirement, and having selected ceramic powders composite active carbon sintering material for use is the filter core material of well head filter.Ceramic powders is fine, epigranular, and it is good to form space throat radius normal distribution performance, compoundly both can obtain good filtration characteristic with behind the activated carbon sintering, can improve it again greatly and filter adsorption function.
Come water to enter the filter water inlet, from the pressure-bearing filter core inner chamber diafiltration of filter core lateral.All solid suspension particle and oil droplet greater than the complex sintered filter core pore constriction of PEC all are trapped within cartridge surface; Less than the solid particle and the oil droplet of filter core pore constriction, part is adsorbed by the filter core material, and part is infiltrated the filter core inner chamber with filtrate, and the liquid that the filter core inner chamber is gone in diafiltration just is cleaned.Hold back or the solid suspension that adsorbs and oil droplet when constantly increasing when filter core outer surface, pore constriction, the candle filter inlet outlet pressure differential can increase gradually, and filtering traffic can be more and more littler.When filtration pressure reduction reaches 1.0～1.5 MPa, can close filter Inlet and outlet water valve, open the backwash flow process, utilize the backwash and regeneration filter core of purifying waste water.According to the raw water quality situation, needed in general 6～8 months filter core drawn off and carry out Chemical cleaning, and then reinstall use and get final product.
The beneficial effects of the utility model are: simple in structure, easy to use, and can carry out assembling match and be applicable according to different injection allocation amounts and water injection pressure, to satisfy water injection in low-permeability oilfield Development and Production needs, improve waterflooding extraction general technical economic benefit.
