Abstract

Featured by high energy density, low combustion pollution and large quantity, natural gas hydrate has become one of the research hotspots in Sanlutian Field of Muri Coalfield since 2008, when China first drilled natural gas hydrate samples in the permafrost area of Qilian Mountains, Qinghai-Tibet Plateau. However, the study on the controlling factors of gas hydrate accumulation is still shallow, which hinders the exploration and development of natural gas hydrate resources. The controlling factors of gas hydrate accumulation mainly include temperature and pressure conditions, gas source conditions, sedimentary conditions and structural conditions, among which structural conditions are the important one. In this paper, the Sanlutian Field of Muri Coalfield in the southern margin of Qilian Mountains is selected as the main research area and natural gas hydrate is taken as the research subject. According to the sample test results, the geological structure pattern is inferred, and the occurrence characteristics, gas source and hydrate composition of Sanlutian gas hydrate samples are further obtained. Finally, the gas hydrate accumulation model at the end of structure is summarized and illustrated.
