摘要
鄂尔多斯盆地内中—晚三叠世形成的一套河—湖相沉积物的含油气层系的延长群含油气层系,由十个油层组(长1-长10)组成,其中长7油层组位于张家滩页岩之上,为胡家村组的下段,张家滩页岩的层位是铜川组的顶部,与其对应的是长8油层组。
The oil and gas-beating series occurring in a set of fiver-lacustrine sediments that formed in the Middle-late Triassic period in the Ordos Basin comprises 10 oil layer groups （from Chang1 to Chang10） , in which Chang7 occurs between the top of the Zhangjiatan shale and the bottom of the Hujiacun Formation. The Zhangjiatan shale is located at the top of the Tongchuan Formation, corresponding to the Changs oil-bearing group.
