Based on the geological interpretation of more than ten thousand seismic profiles of 1000 meters in Sanhu region of Qaidam Basin,this paper shows that two strike-slip faults developed in the basin,among which one in the south of the basin and another in the middle of the basin,while the latter one has played an important role in the formation of the structure of the region.

Previous research has concluded that biogenic gas of the Sanhu region is generated from Quaternary humic source rock.

From analysis of resources distribution types and controlling factors of Quaternary biogas in Sanhu region in Qaidam Basin,three occurrence ways of biogas are pointed out:the low-rate structural traps,the lithologic traps,and the widely distributed water-soluble form.
