深层—超深层白云岩储集层:机遇与挑战
Deep or super-deep dolostone reservoirs:Opportunities and challenges
摘要
Abstract
Deep or super-deep dolostone reservoirs tend to be the important exploration field and targets in the future.Resulting from dolomite replacement and dissolution,abundant volumes of secondary porosity were commonly produced,which made the dolostones the potential high-quality petroleum reservoirs.In this context,it is imperative to reveal the mechanisms of dolomitization,porosity generation and preservation,as well as to investigate responsible fluid attributes and evolution pathay,then to establish reliable geological reservoir models.Under documenting the core issues related to "dolomite problems",this review listed the major dolomitization models,present bandawagons,and main concerns in future dolomite studies,particularly for the deeply-buried dolostones experiencing complicated tectonic and fluid modifications.In China,abundant dolostones occur at great depths of >6500 m in the three largest cratonic sedimentary basins (Sichuan Basin,Tarim Basin and Ordos Basin),which have contributed numerical commercial petroleum reserves and provided favourable opportunities for petroleum exploration in deep or super-deep formations.However,big challenges would also exist due to the great burial depths,multiplephase,superimposed tectonic overprinting and complicated history of basin-fluid evolution.关键词
