文中系统总结了阿尔凹陷石油地质特征,对其地层层序、构造演化、沉积体系和油气成藏条件进行了剖析.通过成藏条件的研究,明确了各层系成藏的主控因素,对油气富集规律进行了总结.同时与二连盆地其它凹陷的简要对比,归纳了该凹陷在构造、沉积等方面的独特特点,指出后期构造反转、陡带沉积体系发育和同沉积背斜构造等特征在二连盆地最具代表性.

The petroleum geological characteristics of Artala sag are systematically summarized,and the stratigraphic sequence,tectonic evolution,depositional system and hydrocarbon accumulation conditions are analyzed.Through the study of hydrocarbon accumulation conditions,the main controlling factors in each formation are determined and hydrocarbon enrichment rule is summarized.Based on a brief comparison between Erlian Basin and other sags,the distinctive characteristics of this sag in the aspects of tectonic and deposition are summed up.The representative characteristics such as later tectonic inversion,depositional system developing widely in steep slope and syndepositional anticline development in the Edian Basin are pointed out.
