摘要: 天然气水合物是极具前景的可接替能源,是当前能源领域研究的热点之一。2017年中国已将天然气水合物列为第173号矿种,并制定了长远规划研发开发技术。天然气水合物的开发是一个涉及温度场、渗流场、应力场及化学场等的多场耦合问题,数值模拟是研究该类问题的重要手段。在简要概述天然气水合物藏的分类、开发方法及全球已开展的天然气水合物试采情况的基础上,系统总结了当前使用的主要天然气水合物数值模拟器及其发展脉络,并对各模拟器的特点进行了讨论对比;尤其重点介绍了使用最广泛的研究型模拟器TOUGH+HYDRATE系列程序。最后讨论了水合物模拟中存在的问题及发展方向,认为水合物藏精细描述、基础模型及参数获取、储层应力特征以及模拟结果可视化等是未来发展的重要方向。

Abstract: 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.

Key words: natural gas hydrate, numerical simulation, simulator, multi-field coupling, TOUGH+HYDRATE
