METHOD OF OIL FIELD DEVELOPMENT Russian patent published in 2009 - IPC E21B43/26 

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production, particularly to multi- and single- layered oil fields development and can be used in horizontal wells. Essence of the invention: methods includes boring of production wells with a horizontal hole and injection wells for pumping water into production stratum in order to flood oil, define productive stratum rock anisotropy coefficient - K_a. If productive stratum rock anisotropy coefficient 4.0≤K_a≤12.0, its horizontal permeability 0.001-0.048 mcm² and its vertical permeability 0.001-0.000083 mcm² execute sequential hydraulic fracturing of the productive stratum in the production well horizontal hole at the single tubing pipe descending - lifting up series. During that maximal half-length of a hydraulic fracturing vertical slot accepted as equal to half of the productive stratum depth. Localise the following hydraulic fracturing zones from the previous hydraulic fracturing zone.

EFFECT: production rate increase, oil recovery increase.
