摘要
郯庐断裂带是中国东部一条巨型断裂构造带 ,该文从郯庐断裂带的几何学、运动学及演化动力学入手 ,分析了其基本构造特征。郯庐断裂带对中国东部中、新生代盆地的形成及演化、油气成藏有重要的控制作用 ,其油气分布具有含油气普遍、油气富集程度差异、“油多气少”及富集非烃气等四个特点 ,并结合勘探实践 ,分析了该断裂带的油气勘探方向 ,认为具有广阔的油气 (包括非烃气 )勘探前景 ,今后的主要勘探方向是渤海海域等区域。
TanchengLujiang fault zone is a giant faultstructure zone in the east of China. Its basic structural features are analyzed in this paper on geometry, kinematics and evolutional dynamics. TanchengLujiang fault zone plays an important role in generation, evolution and reservoir forming of Middle Cenozoic basin in the east of China. Its characteristics of oil and gas are the widespread of bearing oil and gas, the difference of oilgas enrichment degree, 'more oil and less gas' and enriched nonhydrocarbon gas. Combined with the exploration practice, the exploration direction of oil and gas in TanchengLujiang fault zone is analyzed. It is inferred that exploration potential of oil and gas (including nonhydrocarbon gas) is wide, and the next target is the area such as Bohai waters.
