主　　题：Xing'anling Group clay mineral tuff Na^+-montmorillonite argillization 

摘      要：The reservoir of the Xing anling Group in the Beier depression of the Hailar basin is loosely cemented with many tuffaceous *** causes argillization and collapse of the grain framework of the reservoir sandstones.A detailed study on the characteristics of rocks and minerals was carried out through polarized microscope,X-ray diffraction,X-ray fluorescence,SEM and energy spectrum *** results indicate that the reason for argillization is the abundant pyroclastic,and especially tuffaceous,grains in the *** alkaline component is relatively high in some *** are easily altered to montmorillonite in ***+montmorillonite swells strongly when exposed to *** is the fundamental reason for the reservoir s argillization and plugging.
