Oil-forming system is a specific phase of petroleum geology

which emphasizes the analysis of the genetic relation between effective hydrocarbon sag and hydrocarbon accumulotion.The rapid development of sequence stratigraphy has led to the applicatim of sequence stratigraphy to various stages of hydrocarbon exploration.The lithologic and lithofacies study derived from sequence stratigraphy has become one of the most important parts in studying the property of oil generation

reservoing and sealing covering.The framework of sequence stratigraphy provides significant information of strata correlation and sedimentary development for trap forming and hydrocarbon migration and accumulation.In the study of newly developed high resolution petroleum system

high-resolution sequence stratigraphy can provide a serious of important basic parameters such as bed correlation

reservoir physical analysis

the dynamic analysis of oil

gas and water.Sequence stratigraphy play an important role in petroleum system.
