Investigation of rheological and filtration characteristics of sedimentary gel-forming compounds

In producing wells, complete wetting often occurs, during which most of the oil reserves in them remain unproductive. This feature is typical for various fields, as well as for the fields of Kazakhstan. In this case, the most reliable way to increase oil recovery is to limit oil recovery through the use of modern technologies and chemicals. This article discusses the type of technology that allows to increase the efficiency of processing the bottom of the well – the use of sedimentary gel-forming compounds – SRFC the basis of the SRFC technology is to reduce the permeability of the flushed zones in the bottom of the formation and reduce the degree of its heterogeneity. The effect of these formulations is based on the formation of an insoluble precipitate and a gel polymer in the pore space in the lower part of the layer, the specified precipitate and gel block or reduce the permeability of the intervals washed. In the article, as a result of experimental studies, an assessment of the physico-chemical properties of gel-forming compositions was carried out using statistical methods for processing values and analyzing data, in connection with which the rheological properties of sedimentation compositions were simulated, taking into account the composition and average concentrations of various components (polymer, alkali).
