The article presents the results of laboratory studies and pilot tests of plugging materials developed by a team of authors to eliminate steam and water breakthroughs into oil mine workings, and to fill voids in rock massifs in places where steam breakthroughs occur. Conclusions are made on the influence of individual components of the compositions, which allows them to be combined to achieve the required properties of the material. The tests were carried out at an experimental section of the Yaregskoye oil mine and showed the effectiveness of the developed materials. It is planned to further develop this work, including testing the plugging compositions for surface steam injection wells.
