中文摘要: 根据单因素分析多因素综合作图法,对川西北九龙山地区珍珠冲段岩石学特征、沉积构造、植物化石特征等进行详细研究,并结合测井资料,分析九龙山地区珍珠冲段沉积相,深入研究其平面展布特征进行,探讨其演化规律,建立研究区沉积相发育模式。研究认为珍珠冲段沉积期九龙山地区主要发育湿地型扇三角洲相,并且发育一套正旋回的层序,为该地区油气勘探工作提供指导。
Abstract:Based on the single factor analysis and multifactor comprehensive mapping method, a detailed study of the Jiulongshan region Zhenzhuchong segment lithology, sedimentary structures, fossil plants characteristics had been carried out. Combining with logging data analysis, the author studied the sedimentary facies and the plane distribution feature in-depth, discussed its evolution, and established sedimentary facies development patterns in the region. The result showed that the sedimentary facies in Jiulongshan region during Zhenzhuchong segment sedimentary period was a fan delta wetland, and it developed a positive cycle of the sequence, which provided guidance to oil and gas exploration in the region.
