The combustible ice is a kind of new clean energy, and its exploration and development is of great practical significance. The authors engaged in the long-term exploration of coal geology, and are very familiar with the Jurassic Age coal-bearing basin in the Mid-Qilian Area. Based on the three main conditions for the formation, the authors pointed out the direction of searching for the terrestrial combustible ice in Qinghai Province: the main body should be the Jurassic Age coal-bearing basin in the Mid-Qilian Area, and the second is the Wuli Basin in South Qinghai. The combustible ice mainly exists in the interlayer between the permanent and the non-permanent frozen layers of the middle synclinal structure in these coal field areas. The method of searching for the combustible ice is mainly geophysical technology,   well drilling and exploration etc.
