PROCESS OF EXPLOITATION OF OIL FIELD

摘要

oil industry, development of inhomogeneous oil deposit. SUBSTANCE: oil is recovered according to process through production wells. Working fluid and suspension of water-soluble polymer in hydrocarbon liquid are pumped through injection wells. Well is filled with oil-free of water prior to pumping of suspension of water-soluble polymer in hydrocarbon liquid. Suspension is pumped through tubing string sunk beneath perforation interval. Technological curing is conducted in the course of 20-30 h till gel of water-soluble polymer starts formation in conduits of water inflow in drowned part of pool. Volume of liquid equal to pumped volume is smoothly extracted from well with recovery rate determined by presence of water-soluble polymer in extracted liquid. Then well is put in production again. EFFECT: increased recovery of oil from oil field thanks to stronger fixing of water-soluble polymer in pool.
