| 摘 要： | 结合研究区的露头剖面、钻井岩心、测井资料等，对跃进地区下干柴沟组进行了高分辨率层序地层学研究．识别出由V级层序界面控制的短期基准面旋回层序，按结构类型的不同划分为向上“变深”的非对称型、向上“变浅”的非对称型和对称型。阐述了研究区各类短期基准面旋回层序的砂体发育情况。对下干柴沟组中期、长期旋回层序进行了划分，识别出7个中期基准面旋回，3个长期基准面旋回，并预测了岩性油气藏发育的有利相带。

| Abstract: | The study on high-resolution sequences stratigraphy of Lower Ganchaigou Formation of Yuejin Region was made based on the comprehensive analysis of outcrops profile,drilled cores and well logs.The short term base cyclical sequences which controlled by five-grade sequence interface were recognized and divided into 3 types of structures:upwards deeper antisymmetrical sequence,upwards more shallow antisymmetrical sequence and upwards deeper and then more shallow symmetrical sequence.Based on these studies,3 lon... |
