FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil industry, in particular, to preliminary water discharge units and can be used at oil fields. Installation includes wells with pipeline, settling tank separated by blind partition to the section of water separation from oil connected to the pipeline and section of water settling connected to formation pressure maintenance system. Oil-gathering main is connected to both sections, the section of water separation from oil and water settling section are connected by pipeline of contaminated water through control valve and coalescing filter. Control sensor is done as inter-phase level metre located in the section of water separation from oil. The pipeline can have catching device for associated petroleum gas mounted and equipped with gas-gathering main that is connected to oil-gathering main.
EFFECT: increase of efficiency of water-oil emulsion separation to oil and water.
