This article is devoted to the features of improving well construction efficiency, namely, the stationary problem of incompressible fluid inflow into a complex-geometry well. This problem is solved in two dimensions: infinite vertical permeability and zero vertical permeability of formation. We have also measured the increase in the flowing well flow rate in the context of forming long (up to three meters) filtration channels with drills. Currently, there are no effec-tive technologies in this area. Thus, our paper is relevant and significant. This study allows us to conclude that using the proposed drill allows making maximum depth filtration channels.
