Abstract
Abstract The paper presents the results of testing of new production equipment of wells, as well as the operating modes of horizontal wells in the conditions of development of multilayer facilities. The paper also presents the results of drilling small-diameter wells, the methods of oil production intensification, and the principles of operation of pumping equipment with an electric valve with account for optimal draw-downs on reservoirs. The suggested approach to the operation of horizontal, sub-horizontal and directional wells of small diameter allows increasing the technical and economic indicators of the development of complex multilayer facilities. It is proposed to use the developed technology in the operation of two or more reservoirs in conjunction with the implementation of dual injection into the exploited reservoirs through injection wells in the center of the element of development.
