可燃冰是清洁的新兴能源,其勘查和开发具有重大的现实意义。依据陆相可燃冰形成的3个条件,指出了青海省寻找陆地可燃冰的方向,即以中祁连侏罗纪含煤盆地为主,其次为青海南部的乌丽盆地。可燃冰主要赋存在向斜构造中部的永冻层与非永冻层之间,目前寻找陆相可燃冰的技术方法主要有地球物理勘查和钻井勘探等。由于可燃冰的赋存位置被永冻层完全掩盖,因此,在寻找可燃冰的前期阶段物探工作尤为重要。笔者认为物探方法中以直流激电测深的勘查效果较好。
Combustible ice is a clean and emerging energy, and its exploration and development have great practical significance. Based on the three conditions of the formation of combustible ice in the continental shelf, the direction of looking for the land-combustible ice in Qinghai Province is pointed out, which is mainly the Jurassic coal-bearing basins in the Qilian, followed by the Wuli basin in southern Qinghai. The combustible ice mainly exists between the permafrost and non-permafrost in the central part of the syncline. At present, the technical methods for searching for continental combustible ice are mainly geophysical prospecting and drilling exploration. Since the occurrence of combustible ice is completely covered by permafrost, geophysical work is especially important in the early stages of searching for combustible ice. The author believes that geophysical methods to direct current electrical sounding sounding better exploration results.
