Lost circulation in drilling is a common yet challenging issue, often leading to resource wastage, increased operational costs, and potential blowout hazards. Lost circulation impacts drilling efficiency and safety, especially in high-temperature deep formations, where control becomes more difficult. This paper discusses recent advancements in high-temperature resistant plugging materials, focusing on fiber-based, epoxy resin-based, acid-soluble, gel-based, composite, and intelligent materials. These materials have made significant progress in temperature resistance, pressure resistance, sealing efficiency, and chemical stability. By improving composition, processing, and formulations, these materials effectively address lost circulation issues in complex formations. For example, fiber materials enhance fracture bridging, epoxy resin materials exhibit excellent permeability and strength, while intelligent materials can adapt automatically to environmental changes. The paper concludes by recommending further optimization of material formulations, the establishment of evaluation systems, and the rapid selection of suitable plugging materials to improve the efficacy of lost circulation control, ensuring safety and efficiency in high-temperature drilling operations.
