【Abstract】 On the basis of exploration experience of approximately 20 years in Saihantala Sag,a conclusion can be drawn that the main reason for unsuccessful exploration activities is the absence of effective reservoirs,thus,finding favorable reservoir areas plays crucial role in hydrocarbon exploration in the sag.Through analyzing sedimentary facies,distribution of sand bodies,diagenesis and reservoir-influencing factors of main exploration target horizons in the Lower Cretaceous,favorable reservoir areas are synthetically evaluated,which shall provide important bases for hydrocarbon exploration in the sag.更多还原
