| 摘 要： | 徐家围子断陷下白垩统营城组四段是裂谷盆地火山喷发背景下发育的粗碎屑岩地层,是天然气储层。利用该区钻井、岩芯、测井和高分辨率三维地震资料,按照层序地层的原理对营四段层序地层进行了分析,以岩相分析为基础确定了营四段沉积体系类型。研究表明徐家围子断陷营四段发育营四下层序（Sq1）和营四上层序（Sq2）两个三级层序。营四下层序...

| Abstract: | The 4th member of Yingcheng Formation of lower Cretaceous is a series of stratigraphy of coarse clastic rock deposited in a background of volcano erupting of rift basin of Xujiaweizi faulted depression.It is the reservoir for natural gas pool.Using 3D seismic data of high resolution,cores,drilling logs and log curves,the framework of sequence stratigraphy and depositional systems of the 4th member were established by this paper based on sequence principle and the way of lithofacies analysis,respectively.Two... |
