| 摘 要： | 根据砂岩薄片、铸体薄片、扫描电镜、X-射线衍射等分析，采用定量计算方法,对安塞油田长101段储层成岩作用进行研究。研究表明:该区长101段储层砂体成分主要以长石砂岩为主，储层砂岩处于中成岩B期，早期的压实作用、多种矿物胶结作用是造成物性变差的2个重要成岩作用，而溶蚀作用，特别是浊沸石、长石的溶蚀是储层物性变好的重要成岩控制因素。结合成岩作用类型及定量表征将该区成岩相划分为5种类型，成岩相控制了高渗储层的分布。 |

| Abstract: | Based on measurement of thin section,casting thin section,scanning electron microscope,and X-ray diffraction for Chang 101 sandstone reservoir,we use the quantitatively calculating methods to study the diagenesis of Chang 101 sandstone reservoir in the Ansai oilfield.The feldspar sandstone is dominant n the sandstone.The diagenesis of sandstone reservoir is fallen into the middle degree stage B.The actions for the poor-quality reservoir are both early compaction and cementation of several minerals.Dissoluti... |
