    Abstract:

    Deep drilling is a necessary means of obtaining deep oil and gas resources and accurately detecting the deep earth. As the increase of the depths in deep wells and extra-deep wells, the high-temperature environment poses stricter requirements on drilling fluid systems. In recent years, new progress has been made in anti-temperature drilling fluid systems through continuous research. This paper summarizes the research and application of various high-temperature drilling fluid systems at home and abroad, and highlights the advantages and application scenarios of different systems, including high-temperature resistant water-based drilling fluid systems of high-temperature resistant polysulfide drilling fluid, high-density drilling fluid, low-density drilling fluid; high-temperature resistant oil-based drilling fluid, water-in-oil, oil-in-water and reversible oil-based drilling fluid systems; high-temperature resistant solid-free drilling fluid systems such as offshore deepwater solid-free, formate drilling fluid, foam drilling fluid, and weak gel drilling fluid; organosilicon drilling fluid systems and biomass drilling fluid systems. The future development directions is environment friendly, improved high-temperature resistance perpormance, cost reduction and enhanced multifunctionality, which requires continuous technological innovation and cooperation to promote the development and application of high-temperature drilling fluid systems in the drilling industry towards sustainability and efficiency.
