By using the analytical techniques of GC/MS, geochemical characteristics in LC 1 well of source rocks in the south area of western Qaidam basin are analyzed. The analyses of TOC, hydrocarbon generating potential, and types of organic matter and maturity reveal that: in N21 segment, the source rock is common in quality; in the segments of E23—E13,the source rock is high quality; the distribution characteristics of nalkanes from the source rocks change largely, there are single peak and double peak; there are obvious phytane advantages, and the abundance of gammacerane is high as a whole except that some segments have low abundance of gammacerane, indicating a strong reducing environment of deposition.
