摘要

This article develops a synthesis method for a thermal-insulation glass-ceramic material (shlamolite) from drilling waste generated during oil production. Drilling sludge samples were collected at the Komsomolsk oil and gas condensate field (Russia) and subjected to drying and milling. The chemical and phase compositions of the sludge were determined, confirming its suitability as a raw material for producing thermal-insulation materials. A series of raw-material batches and corresponding temperature–time firing regimes were designed for shlamolite synthesis. The physicochemical properties of the synthesized samples were investigated. The optimal composition was identified as a mixture containing 80 wt.% drilling sludge, 15 wt.% sodium hydroxide, 5 wt.% sodium tetraborate, and 10 wt.% water, synthesized at 1000°C. This material exhibited a density of 745.05 kg/m3.
