【摘要】 储层沉积特征是油田开发初期的重要研究内容。研究表明,陈家庄凸起东段北斜坡带沙二段—馆陶组主要发育冲积扇、扇三角洲、滨浅湖滩坝以及河流相沉积。通过岩心相分析进一步划分了各类沉积的亚相和微相类型。在砂体展布特征分析的基础上,结合勘探实践,提出扇三角洲前缘砂、冲积扇扇中水道砂以及滨浅湖滩坝砂为该区最有利于油气成藏的砂体。更多还原

【Abstract】 Research on sedimentary characteristics of reservoir is important at the initial stage of oilfield development. From Guantao Formation to the Second Member of Shahejie Formation, alluvial fan, fan delta, loch beach barrier and fluvial facies were deposited in northern slope belt of eastern Chenjiazhuang Uplift. Through core facies analysis, the types of subfacies and micro - facies of each sedimentation have been distinguished further. The frontal sandbodies of fan delta, channel sand in middle alluvial fan and loch beach barrier sand etc. have been recognized as the favorable ones for oil - gas reservoir forming in this area.更多还原
