METHOD OF DEVELOPMENT OF OIL DEPOSITS Russian patent published in 2010 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil industry and is intended for stimulation of extraction of residual recoverable oil stock from deposits of 3^d and 4^th stages of development. The method consists in watering a production formation through pressure wells, in extracting oil to surface via producing wells; in equalising motion of watering front in the formation and in insulating water inflow in production wells. Production wells watered to established limit values are determined in the process of deposit development. Water tight screens are arranged in wells chosen from that group. According to the invention ultimately watered production wells are shut down and converted to inactive ones. Inactive production wells which are in the way of filtration flows from pressure wells to production wells are chosen for arrangement of water tight screens. Also route of filtration flows is determined by pumping individual tracing agents into each inactive production well at continuous mode of water pumping into pressure wells.

EFFECT: ensuring increased efficiency of process of oil deposit development and increased oil yield from formations.
