Engineering Physics Annotation << Back IMPROVING THE EFFICIENCY OF THE DEVELOPMENT OF LOW-PERMEABILITY RESERVOIRS OF THE TYUMEN SUITE WITH A MULTIFUNCTIONAL CHEMICAL COMPOSITION R.V. VAFIN, R.A. GILYAZETDINOV, R.I. KHAMZIN, L.M. GIMAEVA, E.R. GIMATOV Authors propose ways to improve the efficiency of the development of reservoirs of the Tyumen formation by implementing a systematic approach within the planning of gentle treatment of the bottom-hole zone of the formation with a multifunctional chemical composition. The main difficulties of the full use of the resource potential of hard-to-recover reserves of liquid hydrocarbons are considered. On the example of one of the license areas of the Northern Block of the Shaimsky oil and gas bearing district, the low efficiency of the implementation of point flow-deflecting technologies is shown. The prospects for the use of a multifunctional chemical composition based on the results of experimental and industrial work on objects similar in geological structure have been studied. Within the framework of the conducted research, variants of complex impact on the matrix of rocks are proposed in order to form an effective strategy for oil recovery at the final stage of development, depending on the tasks assigned to the subsurface user. Keywords: multifunctional chemical composition; processing of the bottom-hole zone of the formation; Shaimsky oil and gas bearing area; Tyumen formation; water content of products.
