| 摘 要： | 在对研究区钻井岩芯观察和录井资料以及测试分析资料的基础上,对长武地区三叠统延长组沉积体系的类型进行了系统深入的研究,结果表明:长武地区延长组主要发育辫状河、辫状河三角洲和湖泊三种沉积体系。辫状河三角洲主要由辫状河三角洲平原、前缘和前辫状河三角洲三种亚相组成。详细讨论了不同沉积体系的特征,进而讨论了不同沉积体系平面展布。在上述基础上建立了沉积模式。

| Abstract: | Based on the core observation,well logging and test results,this paper made a systematic and thorough study of the types of sedimentary systems of the Triassic Yanchang Formation in the Changwu area.Braid river,braid delta and lake were found to be three major sedimentary systems developed in the studied area.The braid river delta is made up of braid delta plain,braid delta front and frontier braid river delta.A sedimentary model was established after the features of all sorts of sedimentary systems and the... |
