摘要(Abstract)：

为了研究含油气盆地源岩区之上浅层油气分布规律，在下伏源-断-盖配置向浅层输导油气机理及有利部位研究的基础上，通过确定输导断裂烃源岩供给油气有利区、输导断裂输导油气有利区和区域性盖层向上渗漏油气的非封闭部位，将确定出的3个有利油气输导部位进行叠合，形成了一套下伏源-断-盖配置向浅层输导油气有利部位的预测方法，并将该预测方法应用于港东断裂浅层馆陶组圈闭油气成藏有利部位的预测中。结果表明：港东断裂目前已发现油气主要分布在港东断裂中部附近，与通过该预测方法预测出的港东断裂自下伏源-断-盖配置向浅层馆陶组输导油气有利区是吻合的。研究成果为预测下伏源-断-盖配置向浅层输导油气形成浅层圈闭油气藏提供了依据。
In order to study the distribution law of shallow oil and gas above source rock area in hydrocarbon bearing basins, based on the research of mechanism and favorable locations of underlying source-fault-caprock configuration transporting oil and gas to shallow reservoirs, favorable areas for oil and gas supply from source rocks to transport faults, favorable areas for oil and gas transport along transport faults and unseal locations of the regional caprocks with oil and gas leakage upward are determined. The 3 determined favorable oil and gas transport locations are superimposed to form a set of methods for predicting favorable locations of underlying source-fault-caprock configuration transporting oil and gas to shallow reservoirs, which is applied to the prediction of favorable locations of oil and gas accumulation in the traps of shallow Guantao Formation in Gangdong Fault. The results show that the current discovered oil and gas along Gangdong Fault are mainly distributed near middle part of Gangdong Fault, which is consistent with the predicted favorable areas of underlying source-fault-caprock configuration transporting oil and gas to shallow Guantao Formation along Gangdong Fault using this method. The research provides a basis for predicting shallow hydrocarbon traps formed by hydrocarbon transport from underlying source-fault-caprock configuration to shallow reservoirs.
