摘　　要：天然气水合物商业开采风险很大,需要进行科学的评价和预测,因此开采模型准确与否非常重要。对降压法及注热法开采天然气水合物模型研究进展进行了调研,认为耦合水合物分解动力学过程的多相渗流模型更适合用于评价和预测水合物的开采,但在流动参数、热流动参数、动力学及热力学参数模型化和流固耦合研究方面亟待进一步完善。Commercial exploitation of gas hydrate is high risky and needs scientific evaluation and prediction, with an accurate exploitation model very imporant. The advances in depressurization models and thermal stimulation models for gas hydrate exploitation are suveryed, and it is conceived that muhiphase flow models coupled with a kinetic process of hydrate dissociation may be more suitable to evaluation and prediction of gas hydrate exploitation. However, the researches on modeling of several parameters such as flowing, thermal flowing, kinetics and thermodynamics and on fluidsolid coupling need to be quickly further improved.
