摘要：
The role of cementing in the secure and steady exploitation of natural gas hydrates and other deepwater hydrocarbon resources is of paramount importance. In addressing the distinctive challenges posed by deepwater gas hydrate formations, such as low temperatures, minimal fracture pressures, the inclination towards hydrate dissociation, high-pressure shallow gas zones, and aqueous migration, a spectrum of cement slurry systems has been developed with innovation both domestically and internationally. This scholarly work presents an exhaustive overview of the contemporary research status concerning four pivotal cementing slurry technologies that are specifically adapted for hydrate formations. It conducts a rigorous analysis of the merits and limitations of cementing slurry systems characterized by low-temperature early-strength, low-density early-strength, low-heat generation, and anti-migration properties. Furthermore, it thoroughly investigates the applicability and promise of nascent cementing slurry technologies, which encompass insulating and thermal barrier cementing slurries, microbially induced self-healing cementing slurries, and salt-tolerant cementing slurries, for their utilization in hydrate formations. This contribution aims to furnish the latest understanding and insights into the progressive trajectory of cementing slurry technologies within natural gas hydrate formations, benefiting both researchers and professionals, and catalyzing the advancement of cementing technology in marine natural gas hydrate formations and contiguous scientific fields. © 2024 China University of Geosciences.
