摘要
The analysis of pyrolyzed organic carbon in some mudstones systematically sampled from the Queerquek Formation in the eastern Tarim Basin, the detailed observation and description of cores from the Queerquek Formation of Well Yingdong-2, and the comprehensive interpretation of various 2-dimensional seismic sections indicated that a suite of marine hydrocarbon source rocks with a total accumulated thickness of nearly 100 m occurs at the middle and lower parts of the Middle-Upper Ordovician thick Queerquek marine clastic. Widely distributed in the eastern Tarim Basin, these source rocks overlapped and pinched out eastward in the Luoxi platform margin and westward in the Gucheng-Lungudong platform margin, respectively
