OIL DEPOSIT DEVELOPMENT METHOD

FIELD: oil production industry, particularly specific pattern of wells, optimizing the spacing of wells and may be used to develop underexplored underanalyzed deposits penetrated with small number of wells. ^ SUBSTANCE: method involves making structural productive formation plan; planning producing and injection wells for each production facility; drilling and surveying wells; producing oil via producing wells and injecting displacing agent through injection wells. To plan producing and injection well location structural plan of day surface is additionally plotted. The additional plan contains river and ravine-gulley zones. The plan is superposed with structural productive formation plan and caved, elevated zones, as well as elevation-area formation entries are refined. Dip values in vertical direction are calculated in zones of maximal elevation-area marks inclination in refined plan, wherein above marks correspond to river and ravine-gulley zones. Then effective or total oil-bearing thickness of productive formation is determined. Wells are located in flat zone of day surface, namely under river watersheds, along rivers and under ravine-gulley zone. Wells are drilled along with periodic well bore path correction. ^ EFFECT: increased technological and economical development efficiency of oil deposit confined to elevation roof parts. ^ 1 ex, 2 dwg
