摘要：
Natural gas hydrate is a promising alternative energy source, and one of the current research hotspots in the energy field. In 2017, China categorized natural gas hydrate as the No.173 mineral, and formulated a long-term plan to develop technology for gas hydrate exploitation. The development of natural gas hydrate involves a multi-field coupling problem involving thermal, hydrological, geomechanical, and chemical fields. Numerical simulation is an important method for investigating this type of problem. Based on briefly summarizing the classification and development methods of gas hydrate reservoirs, and the gas hydrate production tests that have been conducted around the world, this paper systematically describes the main numerical simulators for gas hydrate currently in use and their development sequence, and discusses and compares the characteristics of each simulator. In particular, this paper emphatically introduces the TOUGH+HYDRATE series program of the most widely used research-based simulator. Finally, the paper discusses the problems and development directions in hydrate simulation. It is believed that the detail reservoir description, basic model and parameter acquisition, reservoir geomechanical characteristics, and visualization of simulation results of hydrate reservoirs are vital directions for future development. © 2021, Editorial Office of ACTA PETROLEI SINICA.
