摘要
In order to find out the relationship between the mudstone compaction in Cenozoic Strata and the generation and accumulation of hydrocarbon in Huizhou Depression, Pearl River Mouth Basin, characteristics of mudstone compaction were analyzed, genesis of undercompaction was discussed based on maximum pyrolysis temperature and hydrocarbon generation index. The results showed that three different types of compactions in longitudinal direction were rapid compaction in shallow layer, normal compaction and low amplitude undercompaction, rapid compaction in shallow layer was mainly developed in Wanshan Formation and Pleistocene Strata (less than 700 m), normal compaction was mainly developed from the bottom of Wanshan Formation or the top of Yuehai Formation to the bottom of Zhuhai Formation or the top of Enping Formation (1 800~3 200 m), and low amplitude undercompaction was mainly developed from the top of Enping Formation to Wenchang Formation (2 400~4 000 m).
