利用有机质中镜质组反射率测定、干酪根显微组分及类型划分、棒薄层色谱等地球化学分析手段,对兴隆镇中生界生油层及附近新生代生油层的生油能力、有机质特征进行了分析归纳。评价目标区不同洼陷原油物理化学特征,通过油源对比技术解决了辽河油田西部凹陷西斜坡南段油气来源问题,为该区进行下一步勘探指明了有利方向。 Based on the determination of vitrinite reflectance, the microscopic composition and type of kerogen and the geochemical analysis of thin layer chromatography, the authors studied the oil generation ability, organic matter Features were analyzed and summarized. The physical and chemical characteristics of crude oil in different subsidence areas of the target area are evaluated. The source of oil and gas in the southern section of west slope of western Liaohe oilfield is solved by oil source contrast technique, which indicates the favorable direction for the next exploration in this area.
