Аннотация: Changing the direction of flow in a porous medium, in reservoir conditions, is important for increasing the flow of oil to the bottom of the well. The use of flow diverting technologies contributes to the alignment of the injectivity profile of injection wells and the selection profile in producing wells. Due to the heterogeneity of reservoirs in permeability and other properties of rocks, fluid flows have different speeds of movement and filtration. The resulting gradients of speeds and pressures lead to the destruction of rocks and the removal of solid particles along with oil. Very often for various reasons, depressurization of casing strings and watering of wells occur. In work methods of isolation of water inflows with the help of various plugging structures are considered. Among the insulating materials proposed development "Ufanipineft", which have passed industrial tests and showed high success. Many formulations are zoned for the oil-producing regions of Russia and foreign countries.This article discusses current issues of the use of flow-diverting technologies and the isolation of water inflows for the intensification of oil production and the repair and insulation works. The presented insulating and plugging compositions were developed by domestic research and design organizations and zoned in many oil and gas producing regions of Russia. At the same time, in order to ensure high success of the application of new developments and the efficient operation of oil companies, additional research and testing of the proposed new products in specific mining and geological conditions have to be conducted. These technologies are very relevant for the conditions of the Chechen Republic.
