METHOD FOR PREPARING AERATED WATER FOR FORCING INTO BED PRESSURE SUPPORT SYSTEM AND TECHNOLOGICAL COMPLEX FOR REALIZATION OF SAID METHOD Russian patent published in 2007 - IPC E21B43/20 E21B43/40 B01D17/00 

FIELD: oil extractive industry.

SUBSTANCE: in accordance to method and technological complex, multi-phase product of oil product wells is injected into network of collecting pipelines and further into separator. In separator, aforementioned product is divided on incidental gas, water and main gas-water-oil emulsion, which are drained in separate streams; water from separator sent to water preparation block to intake of pass phase separator, where it is separated from remaining gas-water-oil emulsion. Main gas-water-oil emulsion from separator is fed into mixing ejector, which receives remaining gas-water-oil emulsion separated from cleaned water from pass phase separator. Gas-water-oil mixture forming during mixing of emulsions is sent into ejector of multi-phase transport block, and then to intake of separation plant and further into inter-tubular space of sump, through intake of pump into hollow of tubing pipes and again into ejector. During aforementioned round circulation, substance is separated onto gas-water-oil liquid, sent into force pipeline and further to oil preparation plant, and to stream of gas injected into gas line. Cleaned water from pass phase separator is sent into gas saturation block to intake of gas flow controller valve, which also receives incidental gas from separator. Resulting original mixture of water and gas is sent into inter-tubular space of force apparatus of gas saturation block, and then it is received at pump intake and further it passes through ejector through hollow of tubing pipes, where it is additionally mixed with stream of gas injected into mixture along gas line from separator. Further, resulting aerated water is injected into bed pressure support system for forcing into force well.

EFFECT: expanded functional and technical capabilities due to provision of stable and constant mode of transportation and separation of well product with any gas factor while simultaneously providing for utilization of water extracted incidentally and full utilization of incidentally extracted gas as well as usage under conditions of broad range of distances between product and force wells.
