摘要
Based on the data of core,thin section,scanning electron microscope (SEM) and X-ray diffraction analyses,the characteristics of petrology,diagenesis type and sequence as well as porosity evolution of the Jurassic in Baijiahai swell-Fubei slope are studied.The results indicate that the debris components of the Mid-Lower Jurassic in this area are mainly quartz and feldspar with their grains in the manner of concave-convex and stylolite contact,and low textural and compositional maturity.The diagenetic stage is dominated by mid-period A sub-period
