摘要
分析了两江地区成熟源岩、良好盖层、断裂及水动力场分布与已发现油田的关系 .认为源岩、盖层、断裂、水动力场是油运聚成藏的主要控制因素 .该区主要油源岩为青山口组和嫩一段泥岩 ,其演化程度控制着油气聚集的数量 ;盖层控制着油聚集的数量和分布 ;断层是青山口组源岩向下伏泉头组断续发育的砂体条带和砂岩透镜体的运移通道 ;沉积水动力场的分布决定渗透层内流体的运动方向 .源岩成熟区、良好盖层分布区、断裂发育区和水动力场高水位向低水位急剧变化带的叠合带是油运聚成藏的有利场所 .
The paper analyzes the effects of the distributions of matured source rocks, good cap rocks, densities of faults and hydrodynamic fields on the developed oilfields. The result of study shows that oil pools are mainly dominated by source rocks, faults, good cap rocks and hydrodynamic fields. The main oil resourde rock is Qingshan formation and first section of Nengjiang area. The fault is a channel of sand belt of Qingshankou formation intermittently developed down to Quantou formation and sand lenticular body. The distributions of sedimentary hydrodynamic field control the moving direction of fluid in penetrating formation. The areas distributed by matured source rocks, good cap rocks, developed fault and the stack sharply changing from the high to the low of hydrodynamic fields are beneficial to oil pools and should be the main target for oil exploration.
