摘　　要：国外相继发现基岩潜山类油藏,展示了油气勘探一个新领域.裂缝型储层是La Concepcion油田基岩裂缝油藏形成、高产的关键.基底油藏主要分布于基底构造高部,基岩潜山两侧,深入基底的断层是沟通上覆油源岩与基岩储层的主要运移途径.上亿年的沉积间断和风化剥蚀导致区域不整合面下发育较厚风化剥蚀带.以越南Cuu Long盆地潜山油藏为例,由于受断层及不整合面控制,在基岩潜山各部位发育多种形式基岩潜山油气藏类型.Fractured basement reservoir for abroad have been found closely follow after, in world, and have been showed a new area of oil and gas exploration . Fractured reservoir is key factor of high producing for La Concepcion basement reservoir, fractured basement reservoir are mainly distributed high-place of basement structure, and both sides of basement hill. Vertical migration due to rock dilatancy, as well as lateral up-dip migration through faults, are the suggested mechanisms responsible to charge reservoirs. Million years of sedimentation on discontinuous, A long period of weathering,formed erosion of the regional unconformity and developed of thick weathering erosion rock bed. Cuu Long Basin in Vietnam as an example basement buriled hill reservoir, Due to faults and unconformity control, various types buriled hill reservoir formed.
