Abstract
According to the identification mark of the short-term base-level cylce interface and under the guidance of the theory and technology of the high-resolution sequence stratigraphy, the authors divide the short-term base-level cycle of Nadu Formation in Baise Basin into three basic structure types which are up-deepening non-symmetry, up-shallowing non-symmetry and symmetry from up-deepening to up-shallowing. Furtherly in the light of the high or low accommodation, and the thickness of the uprising periods and subsiding periods of the short-term base-level cycle, seven subtypes of structure are distinguished and they are up-deepening non-symmetry of low accommodation (Type A1) or high accommodation(Type A2)up-shallowening non-symmetry of low accommodation (TypeB1) or high accommodation (Type B2)complete～nearly complete symmetry (Type C1)in complete symmetry with the majority of uprising semi-cycle(Type C2) or subsiding semi-cycle(Type C3).In this paper the sedimentary environment,stacking patterns,lithlolgic association and sedimentary dynamic processes of each basic type and subtype of structure is discussed in detail. And the development position of the advantage reservoir sand body in each structure type are pointed out. On the basis of these studies, the change rule and distribution pattern of the short-term base-level cycle sequence are summarized. From the terrigenous to lacustrine environment, the short-term base level cycle sequence types have the change rule that is in succession from Type A1 to Type A2, then to Type C2, to Type C1 Type C3 Type B1 and at last to Type B2.In the structure types of short-term base-level cycle sequence, the advantage reservoir sand body mainly develops in Type A1, secondly in Type A2Type B1 and Type C1. In this paper, the authors also briefly discuss the application of the short-term base-level cycle sequence in oil and gas exploration and development stage.
