超深薄储层综合预测技术在英买力地区的应用
|
摘要
为了落实英买46区块巴西改组薄砂层油藏面积和地质资源量,通过地震响应正演模拟、地震反演、敏感属性相结合,刻画了薄砂层展布特征;在此基础上,应用油气检测技术,落实油气聚集区域。经已钻井验证,预测薄砂层及油气分布与实钻结果的吻合率超过85%。对英买46区块巴西改组薄砂层整体地质认识较以往发生了很大变化,发现薄砂层物源来自东侧,为三角洲水下分流河道沉积,砂体广泛发育,局部呈现间湾特征,为构造控制的岩性油藏。
This paper expounds the development model of sand body of the Cretaceous Baxigai Formation in Yingmaili,Tabei uplift,and proposes a thin reservoir prediction approach.First the distribution characteristics of thin sands are identified with seismic forward modeling,seismic inversion,and sensitive attributes.Then,hydrocarbon detection methods are applied to determine oil and gas accumulation zones.The latter drilling results verify the correctness of our prediction.The coincidence rate of prediction is as high as 85%.Our research has totally changed the geological understanding of the area.Thin reservoirs belong to the delta subaqueous distributary channel deposition mode,and their source came from the east.They are lithologic reservoirs controlled by structures.The research provides a solid foundation for the future exploration and development.
