摘　　要：中国大陆东部的一系列中新生代含油气盆地分布于郯庐断裂两侧或位于郯庐断裂带内,显然,这些含油气盆地的形成演化和分布与郯庐断裂带的活动密切相关。作者以郯庐断裂两侧主要坳陷的构造沉降历史恢复为基础,分析了郯庐断裂两侧各坳陷古热场演化的差异性、主要烃源岩发育及品质的差异性,探讨了郯庐断裂活动与两侧坳陷成烃演化的内在联系,认为郯庐断裂对两侧坳陷的成烃、成藏具有宏观控制作用,而坳陷周缘及内部的构造(断裂)活动则对其在坳陷内的分布有重要的影响。A number of Meso-Cenozoic petroliferous basins in the eastern part of continental China are distributed over both sides of or inside the Tanlu fault zone. It is evident that the formation and evolution, and distribution of these petroliferous basins are related to the development and evolution of the Tanlu fault zone. Based on the reconstruction of the tectonic subsidence history of the adjacent depressions of the Tanlu fault zone, this paper analyses the diversities of the paleo-thermal field evolution and development, and the quality of main source rocks. It also discusses the internal relation between the Tanlu fault and hydrocarbon-generating evolution of the adjacent depressions. The authors think that the control of the Tanlu fault zone on the hydrocarbon-generation and accumulation of its adjacent depressions is macroscopical. The important influence on the distribution of oil-gas in the depressions is caused by tectonic （rifting） activites around or inside the depressions along the Tanlu fault zone.
