Abstract: The organic reefs could be genetically classified into progradational, aggradational and offlapping types, according to the relation between the relative sea level change rate and the growth rate of reefs.Progradational reef (prograding from west to east) of Maokou age could be recognized in Nanpanjiang area,while Changxing age took aggradational reef. Progradational reef (prograding from northwest to southeast) of Changxing age could be recognized in western Hubei,and offlapping reef (offlapping from southeast to northwest)of Changxing age could be recognized in eastern Sichuan Province of China.Different kinds of reefs have their own mechanism and element configuration of reef petroliferous system,which are controlled by relative sea level change.Consequentially,progradational,aggradational and offlapping reef petroliferous systems could be genetically determined. Progradational reef petroliferous system could be found in Nanpanjiang area (Maokou age) and westHubei (Changxing age) Province. Offlapping reef could be found in the eastern Sichuan Province.Aggradational reef petroliferous system could be found in Nanpanjiang area (Changxing age).The idea of genetic types of reef petroliferous system have played an important role in pre-drilling appraisal of hydrocarbon potential for reef reservoir.
