| 摘 要： | 为了提高木里地区天然气水合物的勘探研究水平和钻探成功率,研究天然气水合物形成的基础问题,从油气成藏的观点出发,结合区域地质勘探成果,在分析木里地区天然气水合物成藏所需的物源条件、储集条件、盖层条件、运移方式的基础上,得到木里地区天然气水合物广义自生自储、短距运移成藏模式.并对其勘探远景进行了分析和预测,指出了下一步勘探的有利地区.研究成果对木里地区乃至整个高原冻土区天然气水合物的勘探实践具有一定的参考作用.

| Abstract: | In order to improve the exploration level on gas hydrate and the success rate of drilling at Muli area,this study investigates the basic problems of gas hydrate formation.From the point view of hydrocarbon accumulation,combined with the regional geological exploration achievement,the accumulation mode at Muli area is derived as a self-born self-storage and short-range migration reservoir based on the study on the conditions required in the possession of accumulation,including the material sources,reservoir,seal and migration conditions.In addition,the exploration prospects are analyzed and forecasted.The next favorable exploration areas have been suggested.The results provide a useful reference for the gas hydrate exploration and practice at Muli area and even whole plateau frozen area. |
