Abstract Oil-based drilling cutting residues (OBDCRs) are among the primary solid wastes generated during shale gas exploration and development. Utilizing existing equipment to transform OBDCRs into ceramsites appears be a feasible resource-efficient approach. In this study, building were prepared with incorporating fly ash (a byproduct of coal combustion) as raw materials. The aim was comprehensively systematically investigate physicochemical properties characteristics heavy metals (HMs) in ceramsites. Research shows that can indeed using OBDCRs, which exhibit good comprehensive strong resistance acid/ alkali. main HMs found ceramsite barium (Ba), chromium (Cr), nickel (Ni), lead (Pb), arsenic (As), cadmium (Cd), mercury (Hg). During calcination process, these along foaming agent, underwent mutual melting, resulting formation glass, anorthite mullite. These newly formed phases effectively encapsulated HMs, varying degrees enrichment such As, Ba, Pb, Cr, Ni, except for Cd Hg. However, leaching toxicity significantly lower compared original OBDCRs. Further analysis revealed significant increase proportion Fe–Mn Oxides Organic Matter Cd, while Exchangeable Carbonates forms decreased markedly. This trend clearly demonstrated process modified physical chemical ceramsite, stabilized i.e., migrated from an active state more stable form.
