石柱复向斜上二叠统长兴组层序1高水位体系域中的礁和滩因处于复向斜内部而得以很好的保存.根据钻井证实的礁和滩所对应的地震反射特征,总结出礁和滩的地震相识别标志并进行对比.据此,在地震剖面上对礁滩进行识别,最终绘制出石柱复向斜长兴组层序1高水位体系域中礁滩的平面分布图,简要分析了礁和滩的平面分布特征及其控制因素.

The Upper Permian Changxing reefs and banks that attribute to SQ1 HST in sequence stratigraphy are preserved due to their lying within Shizhu Syclinorium. Based on The characteristics of seismic reflection for reef sand banks that confirmed also by drills, seismic facies marks for the reefs and banks are respectively given and compared with each other and many reefs and banks are identified from all seismic cross-sections. A plane map of Changxing Formation distribution of SQ1 HST reefs and banks is drawn. The distribution characteristics and controlling factors of reefs and banks are analyzed and discussed.
