Abstract
Most of Azerbaijan's oil fields have entered the late stage of development, characterized by a decline in oil production and an increase in water cut. In order to increase the efficiency of the development of a watered formation by redistributing filtration flows and increasing the impact coverage by regulating the gel formation process, a gel-forming reagent, an aqueous solution of sodium silicate, is injected in the depth of the formation. Before injection of an aqueous solution of sodium silicate, carboxymethylcellulose is added to it, while the concentration of sodium silicate and carboxymethylcellulose in the aqueous solution is regulated depending on the temperature at a given reservoir depth and the time required for gelation, and after injection of the gelling agent, it is pushed through with a slug of softened sea or formation water.
