苏北盆地海安凹陷泰一段高分辨率层序地层研究

摘要

运用基准面旋回识别原则,对海安凹陷泰州组一段地层进行高分辨率层序地层划分,将泰一段划分为1个长期旋回,3个中期旋回和4～5个短期旋回,并进行了追踪对比,建立了泰州组一段以中期旋回为单位的高分辨率层序地层格架,并对层序发育的控制因素进行了探讨。%According to the theory of high-resolution sequence stratigraphy,based on the seismic,core and logging data,the K2t1 section of Haian Sag has been subdivided into 1 long-term cycle,3 mid-term cycles and 4 to 5 short-term cycles by the base level cycle rec
