ResumoThe oils from the Quele 1 Well are identified as from terrestrial source rocks based on the following characters: ① Abundant occurrence of rearranged hopanes; ② An unknown C_(30) terpane compound; and ③ the distribution of the C_(19)-C_(26) tricyclic terpanes peaks at C_(19 )and declines with increasing carbon number. Hydrocarbons from the mudstones in the Qakemake Formation (J_2q) are the only sources that possess such unique characteristics, indicating the very source for the oils in the Quele 1 Well. Apparently, the Mesozoic lacustrine sediments in the Quele 1,Kuche Depression serve as the single most important source rocks and the depression is of significant exploration potential.
