万城断裂带构造特征及它源油藏勘探潜力

Structural Characteristics of the Wancheng Fault Zone and Its Exploration Potential for Other-Source Hydrocarbon Reservoirs

对万城断裂带的结构构造进行重新认识,揭示该区域经历了复杂的构造演化过程,其中包括走滑拉分伸展构造与同生构造的叠加和相互作用,这些过程共同形成了复杂的多层断裂系统。同时,对区块内它源油藏特征进行详细分析,发现烃源对油藏的形成具有决定性影响,认为靠近烃源的一台阶区域为有利勘探区。此外,白垩系和潜山地区具有形成新生古储式成藏组合模式的潜力。综上所述,万城断裂带深层具有进一步的勘探潜力,为未来的油气勘探提供了新的方向。

A reevaluation of the structures of the Wancheng Fault Zone has revealed a complex tectonic evolution in the region,including the superposition and interaction of strike-slip,rift-extension structures,and synsedimentary tectonics,which collectively formed a complex multi-tiered fault system.Detailed analysis of the characteristics of other-source hydrocarbon reservoirs within the block has determined that the source of hydrocarbons has a decisive impact on the formation of reservoirs,with step areas close to hydrocarbon sources being favorable exploration zones.Additionally,the Cretaceous system and the buried hill areas have the potential to form new paleo-reservoir assemblage models.In summary,the deeper layers of the Wancheng Fault Zone hold further exploration potential,providing a new direction for future hydrocarbon exploration.
