Water quality filtration and separation equipment for oil field

Abstract

The invention discloses water quality filtration and separation equipment for an oil field. In the prior art, water for the oil field is mainly water produced after dehydration of crude oil and reused for oil field operations, and the water contains more substances such as oil slick, impurities, oil sludge, silt, suspended matters and the like, so that severe pollution can be caused to pipelines, water supply equipment, water storage equipment and stratums. The water quality filtration and separation equipment for the oil field consists of a tank, a water inlet, a water outlet, a filtering filler inlet / outlet and filtering baffles, wherein a cavity is formed in the tank, and a stirrer is arranged in the cavity. The equipment has main purposes that the water produced after dehydration of the crude oil passes through the water quality filtration and separation equipment for the oil field and passes through multiple layers of filtering baffles with different specifications of holes and equipment filled with filtering filler, the filtering effect is not affected no matter how high the pressure of the pipelines of the oil field is, and the oil slick, the silt, the mechanical impurities and the oil sludge are effectively filtered out, so that the water quality is improved and optimized finally, and the water for the oil field is effectively treated.

Description

technical field [0001] The invention relates to a water filtering device, in particular to an oil field water filtering and separating equipment. Background technique [0002] At present, oilfield water is mainly water after dehydration of crude oil, which is then used for oilfield operations. Therefore, the water quality contains various mechanical impurities, oil slicks, sludge, sediment, suspended solids and other substances, so it will affect pipelines and water supply equipment. , water storage equipment and water injection well formations cause great pollution, reduce the service life of equipment, cause serious scaling inside the pipeline, reduce the transmission capacity, and also cause the blockage of formation gaps and reduce the permeability, resulting in a decline in crude oil production, etc. A series of adverse effects. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and provides an oilfield water filtration and ...
