摘　　要：为深入了解我国天然气水合物勘探开发方面的研究进展,在简要概括国外水合物勘探试采的基础上,对我国近20年南海水合物的勘探历程及神狐海域两次成功试采进行了归纳总结,分析了神狐海域储层地质力学特性和水合物开采模拟两方面在当前所取得的阶段性成果,并针对其中存在的出砂机理研究不足、安全指标尚未建立、模型存在局限性等一些问题给出了建议,以期为南海水合物的高效开发研究提供思路与参考。In order to understand the research progress of natural gas hydrate in South China Sea,the result of hydrate exploration and prospecting in foreign countries is briefly summarized,and the history of hydrate exploration at South China Sea in the past 20 years and two successful mining tests in the Shenhu area are introduced as well.The achievement and progress made in the study of the geomechanical characteristics of the reservoirs in Shenhu area and the simulation study of hydrate exploitation at the present stage is analyzed.Some opinions and suggestions are put forward on the problems and deficiencies existing there,such as insufficient study on sand production mechanism,unestablished safety index and limitation of simulation model.It is hoped to provide an idea and reference for the efficient development and study of the hydrate in the Shenhu area of South China Sea.
