摘要：为了研究含油气盆地油气成藏规律，在断裂和砂体空间配置类型及特征研究的基础上，通过不同运移方向下断一砂配置与所形成油气分布之间关系的分析，对不同运移方向下断一砂配置聚集油气的差异性进行了研究。结果表明，油气运移方向不同，断一砂配置聚集油气存在着3方面的差异：断一砂配置聚集油气所需断裂类型不同，垂向运移条件下断一砂配置聚集油气所需的断裂类型是长期活动断裂；侧向运移条件下断一砂配置聚集油气所需的断裂类型是短期活动断裂；断一砂配置聚集油气圈闭类型不同，垂向运移条件下油气聚集圈闭主要有断块、断背斜、断层遮挡、断层一岩性和岩性上倾尖灭圈闭；侧向运移条件下油气聚集圈闭主要有断块和断层遮挡圈闭；断一砂配置油气聚集部位不同，垂向运移条件下油气主要聚集在断一砂反向配置的上盘砂体中；侧向运移条件下油气主要聚集在断一砂反向配置中的下盘砂体中。

Abstract: In order to study the oil-gas accumulation laws in an oil-gas-bearing basin, on the bases of the resear-ches on the matched types between the fault and sandbody and their characteristics, the differences in the oil-gas accumulation by the matches in different migration directions are figured out. The achievements show that because of the different migration directions, there are 3 differences in the above oil-gas accumulation by means of the matches stated above: the needed fault types in the accumulation are different, the necessary fault types by the match in the vertical migration are the ones with long-period activity; while for the lateral migration, the faults should be the ones with short-period activity. The needed trap types in the accumulation are also different, under the condition of the vertical migration, the oil and gas accumulated traps are mainly fault-block, fault-anticline, fault-barrier, fault-lithological and lithology-up-inclined & pointed-out traps; while for the lateral migration, the accumulating traps are principally the fault-block and fault-barrier ones. The matched and accumulated places are different, for the vertical migration, the key accumulated places are located in the upper-side sandbodies with the transoid matches; while for the lateral migration, the oil and gas are generally accumulated in the lower-side sandbodies with the transoid mat-
