Abstract:The Quaternary biogas in the Three Lakes area of the Qaidam Basin is characterized by authigenetic self-stored reservoirs, short burial time, weak tectogenesis and slight stratigraphic deformation. There are a lot of synsedimentary inherited low amplitude structures in Quaternary strata caused by the stable tectonic stress within the study area. The seismic prospecting work is encountered with the problem that it is difficult to discover low amplitude structures and recognize thin-layer sand bodies. The absence of effective traps which can be provided for the exploration is the key trouble which has hindered the breakthrough of the natural gas exploration in this area. It is urgent to consider new exploration methods and thinking for natural gas exploration. Considering the inherited evolution character of the structures between the Earth’s surface and the depth, the authors utilized the high precision remote sensing technique to interpret and map the Earth’s surface so as to find out the structure on the Earth’s surface. The new high resolution remote sensing data were utilized to interprete the raised terrain in combination with the survey of the landform and the integrated evaluation, and the results provide fairly detailed ground support for the selection of exploration targets in the Three Lakes area.
