摘　　要：为了指导在塔中地区发现大规模的志留系黑油 ,通过分析塔中低凸起的演化过程、油气显示分布特征、沥青砂的成因、油气的运聚规律 ,结合宏观的地质背景 ,对塔中地区志留系的成藏模式进行了初步探讨 .研究认为 ,本区志留系主要存在斜坡背景上的构造型、构造背景岩性型、地层超覆型、沥青封堵地层型The structural evolution, the distribution of oil & gas shows, the genesis of asphalt sandstone, and the law of hydrocarbon migration and accumulation in Tazhong low uplift are analyzed in order to seek large scale Silurian black oil. According to the analyzed results and the geological background, the pool-forming modes in this area are discussed. It is held that there are four types of pool-forming modes, and they are the mode of structural hydrocarbon reservoir on the slope background, the mode of lithologic hydrocarbon reservoir on the structural background, the mode of stratigraphic overlap hydrocarbon reservoir, the mode of asphalt sealing hydrocarbon reservoir.
