METHOD FOR ISOLATION OF WATER INFLOW IN HORIZONTAL OR INCLINED PRODUCING WELLS Russian patent published in 1998 - IPC

Abstract RU 2101484 C1

FIELD: oil production industry. SUBSTANCE: according to method, gel-creating solution of polyacrylamide and acid is injected into water inflow interval of horizontal and inclined producing wells. Aforesaid solution is pressure-forced down into bed by water of higher density. Operation is started from remote end of water inflow interval and is repeated with respect to advancing along water inflow interval. Technological delay is undertaken for creation of gel. Well is flushed with hydrocarbon liquid starting from remote end of well. Before carrying out isolation of water inflow, remote producing interval of well is filled with acid. Technological delay is undertaken at mode of bath operation, and acid is pressure-forced into bed. EFFECT: high efficiency. 1 cl
