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.
