成果简介	NOVELTY - Invention relates to oil industry, in particular to methods of oil extraction by means of certain arrangement of design well stock, and can be used in formation of oil deposit development system in oil zone. Technical task of the proposed method is to increase the oil recovery of the oil zone of the oil deposit. Method for development of oil deposit in oil zone includes drilling of production and injection wells, injection of displacement agent through injection well and production through production wells. Two adjacent triangular elements are pre-selected in the oil zone of the oil deposit with oil-bearing thickness of 4.0-7.0 m, developed according to the design triangular grid of 400×400 m, then at corners of each triangular element a production vertical well is drilled, on two non-adjacent sides – horizontal production well with length of at least 200 m, retreating to the corners of the triangular element from 50 to 100 m, and on adjacent side – multi-barrel injection well with four branches directed to angles of triangular elements and subperpendicular to each other, wherein each branch of the multilateral injection well, located on the adjacent side of the triangular element, is drilled with a length of at least 100 m, retreating to the corners of the triangular element from 50 to 100 m, and the other two branches are at least 170 m long, retreating to the corners of the triangular element from 80 to 130 m, horizontal production wells and branches of the multilateral injection well are located parallel to the bottom of the formation and at distance of 2.0 m from it, then deep perforation is performed in horizontal production wells along the whole shaft, besides, each perforation hole is spaced from the previous one by not more than 10-15 m and azimuth direction by not less than 30° from each other subperpendicular to the main shaft. Thus, the proposed development method increases oil recovery of the oil zone of the deposit and increases productivity of wells due to maximum drainage coverage of the deposit by area and section. USE - Oil industry. ADVANTAGE - Increasing oil recovery of the oil zone of the deposit and increased productivity of wells due to maximum drainage coverage of the deposit by area and section. 1 cl
