摘要
According to the core description,analysis of thin section, and based on the well drilling, seismic and physical property, characteristics of carbonate reservoir in Oxfordian of Odjarly are researched. Oxfordian of Odjarly belongs to platform facies, which can be divided into platform slope subfacies,including particle bank, oolite bank and other microfacies. The reservoir lithology in Oxfordian is mainly grain limestone, and the intergranular pores and intragranular pores are mainly reservoir space. The most important elements of destroying reservoir are compaction, pressure solution and cementation.
