摘　　要：在精细分析济阳坳陷埕岛地区断裂分布及发育特征的基础上,利用断层纵向断切层位、断层活动性分析及断面压力分析等3种方法对该地区断层的输导性进行了定性、定量分析。最终结合3种方法的分析结果对研究区内断层的输导性进行了综合评价,优选出了埕岛地区沟通明化镇组的有效油源断层,这些断层组成了明化镇组成藏有效油源输导网,并与明化镇组油气分布相匹配,证实了该评价方法的有效性。Based on a refined description of the fault distribution and growth in Chengdao area, Jiyang depression, three analytical methods, i. e. the longitudinal trunction intervals of faults, the fault activity and the fault-plane pressure, were used to qualitatively and quantitatively analyze the transportation of faults in this area. Finally,combined with the analytical results, a compre- hensive evaluation of transportation was conduc- ted for the faults in the studied area, and the ef- fective oil-source faults to connect Minghuazhen Formation were selected. These faults have formed an effective transportation network for oil accumulaion in Minghuazhen Formation, which is matched with the hydrocarbon distribu- tion in the Formation, confirming that this eval- uation method is effective.
