The mechanical compaction is a main factor , which caused the loss of porosity 机械压实作用是导致砂岩储层孔隙丧失的主要原因。
The major diagenetic events include mechanical compaction , chemical compaction , cementation , replacement and dissolution . the reservoir quality experienced from being destroyed to being enhanced during the whole diagenetic evolution process 主要的成岩作用有:机械压实作用,化学压实作用,胶结作用,交代作用以及溶蚀作用。
