【摘要】：为了研究鄂尔多斯盆地中部浅层侏罗系延安组砂体展布及油藏主控因素,同时实现效益建产,通过运用沉积岩石学和地质学的理论知识,结合野外剖面、单井测井相及岩心观察等资料,对研究区浅层侏罗系延安组进行综合研究,弄清楚了该层系的沉积构造特征、储层物性特征、砂体展布及油气富集规律,为区块的滚动勘探奠定了一定基础。运用理论知识并结合多年矿场实践,总结了浅层侏罗系延安组勘探开发成功经验及认识,摸索出了适合浅层侏罗系延安组的单砂体识别、综合布井、钻井、压裂改造等关键技术,且在合理的产建开发技术政策指导下,实现了浅层侏罗系延安组效益建产,形成了浅层滚动开发特点的效益建产模式,为区块下步产建和开发指明了方向,也为同类油藏的勘探开发提供借鉴。
[Abstract]:In order to study the distribution of sand bodies of the shallow Jurassic Yan'an formation in the central Ordos Basin and the main reservoir control factors, and to realize the construction of production benefit, by using the theoretical knowledge of sedimentary petrology and geology, combined with the field profile, Based on the data of single well logging facies and core observation, this paper makes a comprehensive study on the Yan'an formation of the shallow Jurassic system in the study area, and makes clear the sedimentary structure characteristics, reservoir physical properties, sand body distribution and hydrocarbon enrichment rules of the strata. It lays a certain foundation for rolling exploration of blocks. Based on theoretical knowledge and field practice for many years, the successful exploration and development experience and cognition of shallow Jurassic Yanan formation are summarized, and the single sand body identification, integrated well layout and drilling are found out. Under the guidance of reasonable production construction and development policy, the key technologies such as fracturing and reconstruction have realized the benefit construction and production of shallow Jurassic Yan'an formation, and formed the benefit production model with the characteristics of shallow rolling development. It also provides reference for exploration and development of similar reservoirs.
