SYSTEM FOR HEAVY OIL AND NATURAL BITUMEN DEPOSIT ARRANGEMENT (VERSIONS) Russian patent published in 2014 - IPC E21B43/20 F17D1/16 

FIELD: oil and gas industry.

SUBSTANCE: according to the 1^st version the system includes fresh water source with fresh water pipeline, productive wells connected via product pipeline to oil preparation station equipped with marketable oil pipeline and pipeline of concurrently extracted water, connected to the waste treatment facilities that are connected to injection wells via fresh water pipeline, cluster pump station and water conduit fitted with corrosion inhibitor dosing unit. Well product pipeline is equipped with de-emulsifying agent dosing unit, waste treatment facilities are fitted with trapped oil pipeline for its return to oil preparation station, additionally equipped with product heating system with fuel gas pipeline and associated petroleum gas pipeline, and second purified water pipeline connected to water preparation unit for supply of concurrently extracted water to fine purification at oil extraction volume more than 10% from design maximum volume of oil extraction with purified water pipeline disconnection. Note that water preparation unit is connected to fresh water pipeline for its fine treatment for provision of steam generator by necessary water volume, as well as to cluster pumping station via brine pipeline and finely treated water pipeline with steam generator that is for water heating is connected to fuel gas pipeline and via steam pipe it is connected to the steam-injection wells. According to the 2^nd version productive wells are connected via well product pipeline and booster pump station to oil preparation unit.

EFFECT: increase of arrangement system operation reliability by means of: pumping of steam generated from concurrently extracted water into the bed, partial destruction of emulsion in oil collection system by means of early supply of de-emulsifying agent into well product; generation of water steam from concurrently extracted water through its fine treatment from hazardous impurities.
