摘要
通过对研究区内取芯井的岩芯观察,结合各砂层组的沉积特征及其相应的测井相标志,系统的描述了湖底扇沉积微相的划分及分类,在此基础上研究沉积微相平面及垂向上变化规律,最终建立了湖底扇的立体模型,为以后的类似的研究工作提供了一定的参考作用。
By viewing the cores in cored wells of the research district, combining with the depositional characters of every sand formation and its relevant marks of log facies, the differentiation and sorting of sedimentary microfacies of sublacustrine fan are described systematically; the planar and vertical changing rules of sedimentary microfacies are studied on this base; finally the three-dimensional mode of the sublacustrine fan is established, which provides a certain reference action for similar research work.
