Abstract: Bozhong 34-1 complex fault-blocks zone is located in Yanlu strike-slip fault zone.Affected and controlled by the strike-slip fault zone,faults are developed.Ac- cording to Ncocene faults throw,two fault-groups can be classified,NE fault-group and NW fault-group. Thereinto NE fault-group is a set of normal faults pro- ducing by stretch component of right strike-slip move- ment,and form“Y”font-style fault-group with long- period moving fault.The fault-group is primary path of hydrocarbon migration;while NW fault-group is a set of shear faults producing by right strike-slip movement. Fault scaling of the kind of faults is excellent and favora- ble to hydrocarbon accumulation and preservation.Main oil-bearing formation of this block lies in the lower mem- ber of Minghuazhen,which is argillite with interlaminated sandstone and belongs to shallow-water river-domina- ted delta and meandering river environmental deposits.As the sandstone reservoir has a strong reflection in seismic section,the seismic attributes such as amplitude,energy and etc can be used to predict the reservoir.Due to two different acquisition methods in the seismic block,the method of multi-parameters cluster analysis is adopted to eliminate the shortcomings of single seismic attribute in reservoir prediction and achieves good application.
