METHOD FOR DEVELOPMENT OF INCLINED BURIED MINERAL PRODUCING FORMATION Russian patent published in 2016 - IPC E21B43/28 E21B43/11 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to mining and oil and gas industry and can be used, in particular, in underground well leaching of salt bed, lying at a certain inclination. Method for development of inclined buried mineral productive formation involves drilling of vertical and inclined wells with perforation of wells of different density, pumping in working solution and pumping out productive solution, wherein perforation of holes in injection wells is performed depending on angle of inclination of bed towards its rising or fall, wherein perforation density of 40-45 holes per 1 m is in direction of rising of productive formation, and in direction of incidence of productive formation 6-8 holes are perforated per 1 m.

EFFECT: method increases efficiency of development due to more complete development of inclined mineral buried mineral formation (salt, high-viscosity oil, uranium and copper ores, et cetera).
