METHOD OF WELL-STREAM GATHERING FROM OIL DEPOSIT Russian patent published in 2009 - IPC E21B43/34 

FIELD: oil and gas production.

SUBSTANCE: invention refers to oil industry, particularly to well-stream gathering of oil, gas and water at oil deposit. The method consists in transporting the product of wells via a common collector to the point of oil gathering for successive dehydration and preparation, in control over water cuttings of well production and in preliminary discharge of associated water at sections with high watering for water purification and successive pumping it into a reservoir. Influence of water at each section for associated water mixture ability to purification is additionally controlled by means of sampling. There are sorted out isolated sections with revealed single producing wells or clusters of producing wells connected to one booster pump station, production of which contains water of physic-chemical properties negatively effecting mixture of other wells production. Closed water circulation by scheme "installation of separation - cluster pump station-pressure well-reservoir-producing well" is arranged on sorted out isolated sections to cutting watering of production to 5-10%.

EFFECT: optimisation of process of well-stream gathering of production of oil deposit.
