METHOD FOR OIL FIELD DEVELOPMENT Russian patent published in 2008 - IPC E21B43/20 

FIELD: oil production, particularly enhanced recovery methods for obtaining hydrocarbons.

SUBSTANCE: method involves producing oil via producing wells; injecting working agent through injection wells; changing producing well operation regime to provide water cone lowering; injecting selective waterproofing material in producing well bottom area; performing time-delay to selective waterproofing material setting and hardening and developing producing well. Before producing well shut-down seepage is stabilized in oil field area by injection well operation regime regulation. As producing well operation regime changes the producing well operation is shifted into cyclic regime so that producing well operation time is less than number of days in calendar month. Producing well is operated in cyclic regime up to water cone lowering to provide at least 2% water content decrease. Then time-delay duration is at least doubled in comparison with design time-delay duration to provide selective waterproofing material setting and hardening. After well development reservoir pressure is stabilized in oil field area.

EFFECT: increased efficiency of waterproofing works and increased oil recovery from well.
