CONSTRUCTIONS FOR PREPARATION OF FRESH AND FORMATION WATER FOR SYSTEM OF MAINTENANCE OF OILFIELDS FORMATION PRESSURE

摘要

Structures and preparation of fresh water reservoir to maintain the system pressure oilfield reservoir. The invention relates to devices for cleaning the joint formation waters of oil fields and fresh water surface and underground water supplies. Proposed structures solve the technical problem of increasing the degree of water purification. Structures preparation of fresh and reservoir water for reservoir pressure maintenance system oil fields comprising magnetic separator to a power supply, a vortex mixer, the pressure multisection skimmer with oil skimmer, clean water tank, recirculation of wash water, comprising wash pump, sump, sludge beds, is that according to the utility model they contain series-connected sump with coalescing filter, pressure multiple-skimmer, elements ktrohimichesky skimmer with catalytic filters, vortex mixer, the filter with granular media, a magnetic separator, an ultrafilter with calibrated openings, a tank of clean water, ultraviolet lamps, wherein the sump with coalescing filter pressure skimmer and electrochemical skimmer with catalytic filters are oil-gathering devices whose output is connected to the input of the oil separator and sedimentation sludge removal system are in sludge beds, wherein the electrochemical skimmer configured I.S. m sections divided catalytic filters in each section disposed at the bottom of electropositive and electronegative electrodes. The used granular polystyrene fraction 2-5 mm as coalescing loading. Electrochemical skimmer has 3 flotation cells separated by catalytic filters. The catalyst loaded filter alyumomargantsevym catalyst KLA-7541 fraction 2-5 mm. Electropositive electrochemical skimmer electrodes are made of graphite electrodes electronegative - magnesium.
