摘要
断裂输导系统是油气在地下进行垂向运移的主要通道。它是由裂缝或裂缝-孔隙网络构成的,具有穿层、长距离垂向运移和周期性二个特点,断裂输导系统还可以与连通砂体、不整合面组合形成断裂-连通砂体、断裂-不整合面和断裂-连通砂体-不整合面复合输导系统,它们不仅控制油气成藏模式,而且其沿伸层位控制着油气的空间分布层位。
Fault transport system is the main passage of oil or gas migrating in the vertical direction. It is composed of fracture or fracture - pore network. It owns two characteristics of vertical migration of oil or gas in long - distance and through different strata and periodicity. The combination of fault transport system and connected sandbody, surface of unconformity transport systems form the compound transport systems of fault - connected sand body, fault -surface of unconformity and fault - connected sandbody - surface of unconformity. They control the migration and accumulation models of oil or gas. The extend horizon of fault transport system controls the horizon of oil or gas accumulation and distribution.
