| 摘 要： | 通过研究胜利油田惠民凹陷大芦家断块东营组构造与沉积特征、油气成藏条件和勘探开发情况，指出了该区油气成藏的控制因素，认为构造格架控制了油气区域运移和聚集方向，临邑大断层下降盘形成的逆牵引滚动背斜构造控制了油气的平面分布，三级断层控制了油气聚集，地层和断层的组合关系控制了油气富集部位。 |

| Abstract: | Sandbodies of the Second Member of the Dongying Formation in the Dalujia area, Linpan Oilfield, are mainly lacustrine facies fluvial-dominated delta sedimentary system, and delta front subfacies are in the ascendant, which mainly include mouth-bar, subaquatic distributary channel, subsea natural barrier, crevass-splay, sheet sand, distal-bar and interdistributary embayment. The migration and accumulation of the Palaeogene in the study area, surrounded by sags with rich source rocks, were controlled by faults. The large and small faults were connected into a network. Hydrocarbons migrated along the fault planes in vertical direction and along the reservoirs in lateral direction, forming a networkblanket migration and accumulation pattern. The rich source rocks, favorable migration and accumulation conditions, as well as good reservoir-cap rock assemblages have led to the formation of oil and gas reservoirs. |
