摘要：

Natural gas hydrate (hereinafter referred to as hydrate) is a kind of significant potential efficient and clean resource replacing oil and gas in China, and predominantly occurs within shallow formations in deepwater marine environments. Due to its complex occurrence forms and unique reservoir characteristics, hydrate is prone to phase changes in the process of well drilling, thus leading to wellbore instability. Therefore, high-performance drilling fluid is the key to maintaining wellbore stability under. To develop a low-cost and high-performance drilling fluid system suitable for marine hydrate reservoirs, this paper systematically reviews the characteristics of global shallow hydrate reservoirs in deepwater environments and the associated drilling challenges, and analyzes the mechanism and research status of wellbore instability in marine hydrate reservoirs. Moreover, existing drilling fluid systems for wellbore stability in hydrate reservoirs are summarized, and the design ideas and development directions of future drilling fluid system are proposed. The following results are obtained. First, drilling operations in marine hydrate reservoirs often face wellbore instability challenges caused by unconsolidated shallow formations, narrow safe density windows, hydrate phase transition, and variations in drilling fluid properties. Second, in the process of well drilling, heat and mass transfer interactions occur between drilling fluid and the hydrate reservoir, which subsequently alters the mechanical properties around the wellbore, thus leading to wellbore instability. Currently, physical temperature control and chemical inhibition are the primary methods used to delay hydrate dissociation. Third, water-based drilling fluids remain the preferred choice in marine hydrate drilling. The currently developed systems such as aminebased polymer drilling fluid, dilute silicate drilling fluid and polymeric alcohol drilling fluid perform well in hydrate inhibition and wellbore stabilization. In conclusion, future efforts should continue to focus on developing efficient, low-cost hydrate phase control agents and nontoxic, high-performance drilling fluids, and constructing more environmentally friendly, low-cost, high-performance drilling fluid systems that are applicable to marine hydrate drilling and can effectively maintain wellbore stability, so as to provide strong technical support for the development of global marine hydrates and the increase of deepwater oil and gas reserves and production. © 2025, Natural Gas Industry Journal Agency.
