Expermentally-Тheoretical Substantiation and Development of Technological Facilities for Reducing Oil Wells Flooding in Simultaneous and Separate Exploitation of Several Lodes

Nowadays there arises a very important problem of improving the operation efficiency of the multilayer oil wells resulted from the reduction of operating costs by means of controlling the time of selection and intervals of the well equipment operation, depending on the current content of the produced water in the composition of the borehole fluid coming simultaneously from several payout beds onto the bottomhole of these wells. According to the results of experimental research and theoretical elaborations, we obtained an analytical (generalized) dependence of the electrical resistance of the oil-water mixture for the real oil of different regions in a wide range of these impacts changes. We developed a technology and tested on the bench the prototype model of the device controlling the flooding reduction process in multilayer oil wells which are simultaneously exploiting several payout beds. We used a method of selective throttling of formation water entering the bottomhole.
