摘要
扶余油层的油气来自于其上覆的青一段(K2qn1)泥岩,属于老储层新油藏。扶余油层成藏的主要控制因素在于:敖古拉断裂对古龙凹陷生成的油气向西运移具有封堵作用;断层是油气向下运移的有利通道;青一段泥岩异常压力是油气向下排烃成藏的主要动力;储层物性控制了油藏的充满程度。
It is an important reserve replacement zone of Daqing Oilfield,in which there are mainly lithologic and fault-lithologic reservoirs.The oil and gas of Fuyu oil layer came from the upper first section of Qinshankou （K2qn1）mudstone.The main controlling factors of oil accumulation are following as：hydrocarbon westward migration in Gulong sag was hindered by Aogula fault zone,faults were beneficial passages for hydrocarbon migrating downward,the main power of hydrocarbon migration downward was the abnormal pressure of K2qn1 mudstone,and the full extent of reservoir was controlled by porosity and permeability of reservoir.
