TRANSPORTATION METHOD OF HIGHLY WATER-FLOODED PRODUCT OF OIL DEPOSIT WELLS Russian patent published in 2012 - IPC F04D15/00 F17D1/14 

FIELD: oil and gas industry.

SUBSTANCE: invention is used at transportation of highly water-flooded product of oil deposit wells by means of booster pump stations to oil treatment plants. Reservoirs are filled and fluid is pumped out at certain intervals from reservoirs to pipeline. First, demulsifier is dosed to the fluid. After the reservoir is filled, exposure takes place for separation of fluid in the reservoir into oil, water and gas. Oil and water is pumped out in turn from each reservoir with the pump of increased capacity. Increased capacity of pump is chosen on the basis of pumping to the pipeline of fluid volume during the pumping-out period, which is equal to the fluid volume continuously supplied to reservoir during filling, exposure and pumping-out periods. Waste gas is supplied to gas line under proper pressure.

EFFECT: reducing the pipeline pressure and the costs for oil pumping, treatment and water cleaning at well product treatment facilities.
