Abstract
The utility model relates to the field of oil production water injection, and particularly relates to a top squeeze type water injection filtering device for oil production wells. The technical scheme is that the top squeeze type water injection filtering device comprises a housing, a filtrate inlet, a filtrate outlet, a motor, stirring blades, an inlet, a pressure plate, an air outlet and fiber balls, wherein the filtrate inlet is formed in one side of the top of the housing, the filtrate outlet is formed in the bottom of the housing, the motor is arranged on the bottom of the housing, the motor is connected with the stirring blades, the fiber balls are arranged inside the housing, the inlet is formed in one side of the housing, the air outlet is formed on the side of the top of the housing; the pressure plate is arranged inside the housing, and the pressure plate is placed above the stirring blades. The top squeeze type water injection filtering device has the beneficial effects that the filtering device has the characteristics of through backwashing, small filtering material damage, high filtering precision and backwashing water conservation; the water injection efficiency of the oil wells is improved; the pressure plate is arranged inside the housing, the pressure plate is a sieve plate used for replacing a primary non-compression type water distribution sieve pipe, so that the filtering quality is improved.
Description
Technical field
The utility model relates to a kind of oil-extracting and water-injecting field, and particularly a kind of producing well is used pressure type water injection filter.
Background technology
China oil field enters development late stage in succession, and the water injection rate to old filed and injection water quality require more and more higher.New, visit in reserves, hyposmosis and extra-low permeability reserves are newly verified and account for 70% left and right of gross reserves by China, the hyposmosis reserves that does not employ in the whole nation account for more than 60%, and at present conventional filter is not high to sewage disposal precision, is difficult to reach the requirement of water injection in low-permeability oilfield water quality index.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of producing well to use pressure type water injection filter.
Its technical scheme is: comprise housing, filtrate import, filtrate (liquid, motor, paddle, entrance, platen, venthole, fibrous nodules, top one side of housing is provided with filtrate import, housing bottom is provided with filtrate (liquid, described housing bottom is provided with motor, and motor connects paddle, and enclosure interior is provided with fibrous nodules, one side of housing is provided with entrance, case top side is provided with venthole, and described enclosure interior is provided with platen, and described platen is positioned at the top of paddle.
On described filtrate (liquid, connect sparge pipe.
The beneficial effects of the utility model are: filter have backwash thoroughly, little to filtrate injury, filtering accuracy is high and save the features such as backwash water, improved flushing efficiency, enclosure interior is provided with platen, platen adopts sieve plate, the water distribution screen casing that has replaced former non-compression type, has improved filter quality.
