| 摘 要： | 古近系深层砂岩储层是目前惠民凹陷主要的勘探目的层,研究其储层特征及控制因素对凹陷内勘探井位的部署有着重要的指导意义.经过研究,区内沙三段和沙四段砂岩储层物性较好,属于中孔-中渗透性储层,其余层位储层物性较差,多属于低孔-中低渗透性储层.储层性质主要受到沉积条件、压实作用、胶结作用及溶蚀作用的控制,其中压实作用对储层物性影响最大,然后依次是溶蚀作用、沉积条件和胶结作用.

| Abstract: | The deep Eogene sandstone reservoir is an imporotant exploration target of Huimin Depression.Study of reservoir quality in this area plays a directive function on deployment of oil wells.In the studing area,the quality of Es3 and Es4 sandstone reservoir is well belonging to mesoporosity-mesopermeability reservoir,others sandstone reservoir quality is lower.The control factors of reaervoir quality contain deposition,compaction,cementation and denudation.Compaction is the most important affecting factor on re... |
