伊川盆地基底上三叠统发育良好,含大套暗色泥岩,处于晚三叠世洛阳盆地南部沉积中心地带。燕山晚期逆冲推覆构造是伊川地区上三叠统主导构造,逆冲前陆区上三叠统保存较好。伊川盆地上三叠统有机质在早第三纪末—晚第三纪末处于生油高峰期,逆冲前陆区与逆断层有关的早第三纪初构造圈闭和构造—岩性圈闭对上三叠统油气有效。伊川盆地上三叠统具有一定的油气前景,可作为外围新区新层系、新领域油气勘探的突破口。
The Upper Triassic in the Yichuan Basin is well developed and contains a large set of dark mudstone, which is located in the sedimentary center of southern Luoyang Basin in the late Triassic. The Late Yanshanian thrust nappe structure is the dominant structure of the Upper Triassic in the Yichuan region, and the Upper Triassic in the thrust foreland region is well preserved. The Upper Triassic organic matter in the Yichuan Basin was at the peak of oil production from the end of the Early Tertiary to Late Triassic. The Early Tertiary tectonic traps and tectonic-lithological traps associated with thrust faults in the thrust foreland Effective on the Upper Triassic oil and gas. The Upper Triassic in the Yichuan Basin has a certain oil and gas prospect and can be used as a breakthrough point in the exploration of new strata and new fields in the peripheral area.
