FIELD: oil and gas industry; drilling of wells.
SUBSTANCE: invention relates to inhibition of formation of controlled-release deposits, their production and use in underground hydraulic fracturing operations in oil and gas wells and industrial water supply systems. And also relates to a composition and method of producing and using controlled release deposition formation inhibitors, where the compositions contain polyphosphate glasses having predetermined dissolution rates, for controlled release of chemical inhibitors in formed hydraulic fractures during hydraulic fracturing of oil and/or gas formations, and provides inhibition of deposits in industrial water supply systems.
EFFECT: technical result is longer duration of inhibition, stable release of inhibitor in high-temperature conditions.
