摘要
Abstract
The Es2-3 Member with buried depth more than 3500m in Banqiao-Beidagang area, consists of clastic rocks, develops a sedimentary system mainly containing deep-water turbidite fan,fan delta and alluvial digitate sand bar. On the basis of research results of the sedimentary feature, the authors mainly studied lithologic features, diagenesis and rock evolution stages by means of rock thin section, cathodology, SEM, X-ray diffraction, as well as vitrinite reflactance. Meanwhile, we have made both the deep sandstone reserving ability evaluation and the causing factors analysis, and found out that the pore type of the reservoir in Banqiao-Beidagang area is dominated by secondary pores that make up two secondary pore zones. This study also indicates that it is the abnormal high-pressure zone and the organic matter that caused formation of the secondary pores directly.关键词
