Abstract

The invention discloses an adjustable sewage filtering apparatus for an oil field, relating to the field of water treatment of environmental engineering, in particular to sewage treatment equipment applied to an oil field, comprising a tank body (2) provided with a water inlet (7) and a water outlet (3) and a hydraulic control mechanism (1) arranged on the tank body (2), wherein the tank body (2) is internally provided with a water distribution device (6) and a water collection device (4); a press plate (10) is arranged between the water distribution device (6) and the water collection device (4); a fiber bundle filter material (5) is placed between the press plate (10) and the water distribution device (6); and a piston rod of the hydraulic control mechanism (1) is connected with the press plate (10). A drain outlet (11) is arranged at the bottom of the tank body (2). The filter precision of the filter material is adjusted by connecting the hydraulic control mechanism with the filter material, thereby achieving the aim that the water quality reaches the standard in such a way that the filter precision is controlled according to the press degree of the filter material.

Description

technical field [0001] The invention relates to the field of water treatment of environmental engineering, in particular to an adjustable sewage filtering device applied in oil fields. Background technique [0002] With the development of oilfields, the water content of oil well production fluid is getting higher and higher, and the water content of some oil well production fluid is as high as 95%. The oily sewage has high salinity and serious environmental pollution. The best outlet for these produced water is to re-inject into the formation after treatment. Low-permeability oil layers, especially ultra-low-permeability oil layers, have higher and higher requirements for reinjected sewage water quality, and water purification technology is particularly important. The produced sewage of most oil fields is concentrated in the sewage treatment station for treatment, and generally adopts primary filtration or sedimentation treatment, and its water quality is difficult to meet ...
