摘　　要：为了深入了解储层孔隙演化特征及成岩作用对宝浪油田储层物性的影响,通过岩心、岩屑观测,薄片鉴定、X衍射分析、扫描电镜分析等方法;总结了储层的岩石特征和成岩作用类型。按其对储层储集物性的影响,把它归为破坏性成岩作用和建设性成岩作用,且分析了这2类成岩作用在孔隙空间的形成过程中对储层物性的影响。In order to understand the impact of pore evolution and diagenesis on reservoir petrophysical property of Baolang oilfield, reservoir rock property and diagenesis are studied by using methods of core and cuttings observation, thin section appraisal, X-diffraction analysis, and scanning electron microscope. According to the influence on petrophysical property, reservoir diagenesis is classified as destructive and constructive type. The influence of these 2 diagenesises on petrophysical property in the process of forming pore space is also analyzed.
