The article analyzes the problem of improving the quality of demarcation of rocks, oil as well as gas horizons. The results of theoretical and experimental researches of the backfill materials expanding at hardening on the basis of ash mixes are stated. Clinker heat-resistant autoclave hardening backfill materials that expand during hardening, with high performance properties on the basis of man-made by-products of industry have been developed and studied. The selection of optimal formulations of new heat-resistant backfill materials of autoclave hardening, which expand during hardening, is carried out. The results of the work have practical application in the cementation of oil and gas wells in complex mining and geological conditions in exploration areas and industrial fields of oil and natural gas as well as gas condensate.
