摘要:
通过对吴堡地区延安组延10层的研究,弄清油藏富集规律和储层的控制因素,为区域勘探和后期注水开发指明方向,从而推进勘探开发的步伐,在提高经济效益的同时探索勘探思路、方法及技术,为实现油气勘探突破提供技术支持。运用沉积岩石学和层序地层学的理论体系,根据野外露头剖面、单井测井相分析及现场岩心观察等,结合延10油层组的岩性特征、测井相特征、沉积构造和沉积相特征等多种手段,识别出沉积相和沉积体系的平面展布规律。研究认为吴堡地区延10为辫状河沉积,主要发育河床滞留沉积、河道砂坝沉积微相,河道边部发育河漫滩亚相。结合沉积相带分布和砂体展布规律、储集层特征和顶面构造等方面进行分析研究,明确吴堡地区延10油层组的主要控制因素。
Abstract:
This paper studies the pattern of oil deposit and the controlling factor of the reservoir in Wubu District by researching Yan 10 reservoir,the main reservoir in Group Yan’an,and shows the way of further surveys and waterflooding in later period,which promotes the development of exploration in this region.Meanwhile,it also discovers effective thoughts,methods and technologies to provide technical support for the breakthrough of oilgas exploration.Using the theoretic system of sedimentary petrology and sequence stratigraphy,combining the information of field outcrops,the analysis of electrofacies,the observation of the core and the features of Yan 10 reservoir and electrofacies,and sedimentary tectonics and facies,the author distinguishes the plane distribution pattern of sedimentary facies and sedimentary system.The research shows that Yan 10 reservoir in Wubu District is braided river deposit with lag deposit on the riverbed,bar microfacies and river flood subfacies.Combining the distribution of sedimentary facies belt,the distribution pattern of sand bodies,reservoir capacity and the top structure,the paper makes the main controlling feature of Yan 10 reservoir in Wubu District clearer.
