摘要
mary name="EnDivSummary">Located in Qinghai-Tibetan Plateau, the Cenozoic Qaidam Basin owes its development to the formation of the plateau, and the complex structures at different sites play an important role in the formation of various interpretations. In addition, the seismic data over faulted belts of the Qaidam Basin are usually very insufficient for interpretation. So different well designers have different inclinations in the choice and evaluation of structural traps for drilling. Based on seismic and remote sensing data, the authors interpreted the Lenghu strike-slip fault belt as dextral displacement. However, there existed an inversion of early extensional strike slip in Paleogene period, and the inverted strike slip deformation controlled secondary accumulation of strike slip faults belts.
