摘要
To understand petroleum geology role of carbonate rock stylolite,this paper stated the research advances of the cause,type,material composition and diagenesis of the carbonate rock stylolite and its role on the carbonate rock thickness recovering,generation,expulsion,migration and accumulation of petroleum.Research in the distribution,type and genesis of stylolite is relatively mature and it was concluded that stylolite resulted from the contact of stress and solution.Stylolites consisted of clay,quartz,solid organic matter,bitumen,and secondary minerals such as pyrite,calcite,etc.Its formation resulted in the reduction of carbonate rock thickness.Stylolites played an important role on the petroleum migration and accumulation due to secondary alteration.In the area with low abundance of organic matter,organic-rich stylolites had significant meaning to the generation-expulsion of hydrocarbons.However,the research was far from enough.In the future,more attention should be paid to the role of carbonate rock stylolites on the petroleum migration,accumulation,organic matter enrichment and mechanism of hydrocarbon generation & expulsion.
