Abstract
There are a huge number of types of well operations that involve pumping various reagents into the reservoir through the well. In this case, there may be a need for destruction and removal of the reagents used, associated with non-standard or technological problems, for example, undesirable deterioration of the filtration properties of the reservoir in the bottom-hole zone, blocking the well or bottom of the well. In this case, breakers are used – reagents that destroy or change the physical and chemical properties of certain chemical products, after which they can be easily removed from the well. Temposcreen-Plus reagent is applied for water shutoff. This article presents the results of laboratory studies of the effectiveness of various breakers for the destruction of polymer-gel systems based on the Temposcreen-Plus reagent. Some aspects of methods for studying the physical and chemical properties of polymer dispersed systems are also described.
