METHOD OF OPERATION OF WELLS WITH STOPPED FLOWING Russian patent published in 2003 - IPC

FIELD: oil and gas producing industry; applicable in oil production from wells with stopped flowing due to drop of formation pressure or increased water encroachment. SUBSTANCE: method includes supply from surface of gas to well with stopped flowing; lifting of gas-fluid mixture with various ratio of its gas and fluid components through lifting channel formed by space of tubing string installed in well, or annular space between said tubing string and well walls; supply of said gas-fluid mixture to products collector. Well with stopped flowing is connected with flowing well by pipeline including booster pump. Coming from flowing well oil-gas products, completely or partially, are directed to booster pump, and from booster pump, to well with stopped flowing, with subsequent lifting of these products through lifting channel together with products of well with stopped flowing. If supplied to booster pump is only a part of oil-gas products from flowing well, ratio in it of gas and oil components is left invariable, or varied by separation in separator included into pipeline interconnected said wells, between flowing well and booster pump. A part of oil or gas component is discharged into products collector to bypass well with stopped flowing. EFFECT: provided well operation in conditions of absence of high-pressure gas source. 2 dwg
