摘要
大兴砾岩体位于廊固凹陷西部，为冲积扇——扇三角洲沉积体系，是本区具潜力的勘探目标，通过岩石录井资料和三维地震资料分析，建立了砾岩体剖面识别模式，并划分出两种不同的砾岩体油藏类型，揭示了本区砾岩体的三维空间分布特征，研究表明：大头断层下降盘砾岩油气藏有着比较好的盖层和油源条件，本区存在两种不同的砾岩油气藏类型可供勘探，并将油藏描述技术成功地运用于砾岩油气藏的勘探．
Daxing conglomerate reservoir located in the west of Langgu Sag is a alluvial fan fan delta depositional system.Based on the analyses of log data and 3 D seismic data,the mode is established for identifing conglomerate body seismic reflection.Reservoir description is successfully applied in the identification of conglomerate reservoir.The spatial distribution feature of conglomerate in this region is given.The research results in this paper show that the delta regime is an exploration target with great potentiality.And the conglomerate reservoir in the downthrow block of Daxing fault has better cap formation and oil source condition.
