摘要
油气输导体系和油气运移的特征决定油气藏形成与分布。惠民凹陷商河地区地质条件分析结果表明,其输导体系空间配置构成4种模式:砂体—断层—砂体、砂体—断层—不整合、砂体—火山锥以及砂体—断层—火山锥;该区主要发育的是阶梯型输导体系分布组合,以断裂、骨架砂体共同构成的运聚体系呈阶梯型输导,导致油气爬坡运移、单层系成藏。
The distribution and forming of the reservoir depend on the types of the hydrocarbon transport system and the features of the hydrocarbon migration. The geologic conditions of the Shanghe area in Huimin Sag is analyzed, the result show that the types of its hydrocarbon transport system spatially have four modes, they are＂sand body-fault-sand body＂,＂sand body-fault-unconformity＂,＂sand body-volcanic cone＂and＂sand body-faultvolcanic cone＂, It was mainly developed step- transport system distribution combination, the migrationconcentration system which was consisted of fault and frame sand body jointly showed step transport, it resulted in reservoir forming by migrating upwards and single-layer.
