| 摘 要： | 根据连通砂体、断层和不整合面特征,建立了马海―南八仙构造带输导体系类型,并系统总结其成藏作用。研究结果表明:马海―南八仙地区主要发育连通砂体、断层及不整合3种油气运移通道,形成了断层单一型、断层―砂体复合型和断层―不整合复合型输导体系,这些输导体系控制了油气成藏类型、成藏期次、油气运移距离和油气空间分布规律、生储盖组合形式,并决定了马海―南八仙构造带具有"油气多层系分布,油气藏类型多样"的特点。 |

| Abstract: | The hydrocarbon pathway systems in the Mahai-Nanbaxian area have been established based on the characteristics of connective sandbody , fault and unconformity , and then their contributions to hydrocarbon accumulation were evaluated.The results show that the connective sandbody , fault and unconformity are mainly developed in the Mahai-Nanbaxian area.They can be combined to form three hydrocarbon pathway systems : fault single-pathway system , faultsandbody complex pathway system and fault-unconformity complex pathway system.These hydrocarbon pathway systems dominate the reservoir type , hydrocarbon accumulation phases , hydrocarbon migration distance , hydrocarbon spatial distribution and source reservoir cap combination , which result in the diversity of oil-bearing series and reservoir types in the Mahai-Nanbaxian structural belt. |
| Keywords: | connective sandbody fault unconformity pathway systems accumulation effect |
