摘要
The invention relates to the oil industry, in particular to the development and exploitation of oil deposits splitters horizontal wells.; The invention makes it possible to increase the oil recovery for heterogeneous reservoir permeability and reduce the amount and cost of drilling.; The goal is achieved by the fact that an oil field with a nonuniform permeability collector wells drilled out sparse grid. Each well has a main bore and sidetracking system with a horizontal fan-radially-symmetrical in the direction of the productive formation interval. Completion of the main and lateral boreholes in the open hole interval of the productive stratum produce filter-shanks. Filter the shank is the shank - a perforated casing surface, after which the installation is rendered Filter - artificial porous medium, which is a dummy ground, consisting of ceramic balls of the same diameter with cubic packing. The filter design involves extracting it from the well to mechanical or chemical cleaning.; 3 yl.
