| 摘 要： | 本次研究依据大量的钻井、露头和岩心资料,根据沉积构造、沉积层序特征及测井曲线对比分析,对姬塬地区延九段的沉积相进行研究,认为本区延九段为潮湿气候条件下的辫状河—辫状三角洲沉积,且明确了沉积相的时空展布和变化规律。研究区辫状三角洲平原上分流河道比较发育,还发育分流间、决口扇和沼泽沉积;三角洲前缘上主要发育水下分流河道和水下分流间。研究区储层砂体发育各种层理构造和侵蚀构造。河道砂坝储层物性好,常叠覆形成构造小高点,可形成构造-岩性油藏。 |
| 关 键 词： | 辫状三角洲 河道砂坝 延安组 侏罗系 鄂尔多斯盆地 |

| Abstract: | Based on large quantities of drilling and core data,according to analysing the sedimentary structure,sedimentary sequence and well logs,the sedimentary microfacies of the ninth member of Yan'an Formation in Jiyuan Region was studied.It was considered that braided river-braided delta system was deposited under moist climate at the moment.The distribution of that system was indicated.Distributary channel,interdistributary bay,crevasse fan and swamp were developed in the braided delta plain.Underwater distribu... |
