摘　　要：巴布亚褶皱带的地震资料品质差,变形机制不明,地震解释模式的不确定使得地震解释多解性强;且不同构造带变形特征、油气分布差异大。运用沙箱模拟实验明确构造解释模式,采用轴面分析开展地震构造解释,并开展平衡剖面恢复对解释成果进行验证,最后通过构造解释厘清了褶皱带的构造特征,指明了有利构造区。The seismic data quality in the Papua Fold Belt is poor,and the deformation mechanism is unclear.The uncertainty in seismic interpretation models leads to strong multi-interpretative nature.Moreover,there are significant differences in deformation characteristics and hydrocarbon distribution across different structural zones.This paper employs sandbox simulation experiments to clarify structural interpretation models,uses axial plane analysis for seismic structural interpretation,and conducts balanced profile restoration to validate the interpretation results.Finally,the structural features of the fold belt are clarified through structural interpretation,identifying favorable structural areas.
