The purpose of this work is to improve the design of injection wells in a low-permeable reservoir to increase the efficiency of the reservoir pressure maintenance system. The object of the study is the West Siberian field, which has ultra-low reservoir properties. The producing and injection wells operation is analyzed, the zones of effective influence of reservoir pressure maintenance are identified. Multivariate hydrodynamic calculations are carried out, which differ in the design of injection wells (multilateral wells). The calculation results show that the drilling of a multi-hole injection horizontal well (HW) has several advantages: an increase in injectivity, in oil production rate and in total oil production.
