中文摘要: 东营凹陷位于济阳坳陷的东南部。通过岩心观察、薄片鉴定、物性分析、扫描电镜观察等技术手段,研究了东营凹陷永北地区砂砾岩体储集层的主要岩石类型、储集空间类型、物性特征和影响因素。研究结果表明,砂砾岩体岩石学特征具有成分成熟度和结构成熟度低的特点;主要储集空间类型为粒间溶孔和粒内溶孔,铸膜孔和胶结物溶蚀孔也具有一定的储集意义。影响本区储集物性的因素主要有埋藏深度、成岩作用以及沉积相带,其中埋藏深度是控制储集层物性的主要因素。

Abstract:The Dongying sag is located in southeastern part of the Jiyang Depression.A study has been made on main rock types,type of reservoir space,physical characteristics and affecting factors of the glutenite reservoirs in northern Yongxin area in the Dongying sag based on core observation,thin section analysis,physical property analysis,scanning electron microscopy.The results show that the glutenites are of a low compositional maturity and textural maturity,and the reservoir spaces are intergranular corroded hollow,moldic pore and cementing corroded hollow.The dominant factors affecting physical characteristics of the reservoirs include burying depth,diagenism and sedimentary facies,of which the burying depth serves as a fundamental factor affecting physical properties of the reservoirs.
