摘　　要：新北油田馆上段油藏不同断块、构造部位的井虽然埋深相同,但油水层的电阻率差别较大,开发生产中发现大量低电阻率油藏。通过油藏描述、测井解释、流体和岩矿分析化验等技术手段,探讨了低电阻油层的影响因素及原因。这些低电阻率油藏的主要影响因素是断层造成地表浅海水渗滤后地层水矿化度升高引起的;其次是曲流河沉积的岩石的泥质含量、岩石骨架颗粒和粘土矿物种类;个别井层的低电阻率也与油层的厚度、油藏高度、岩石的润湿性和特殊导电矿物具有一定关系。Although the wells in different fault blocks and structural parts of the upper section of Guan-tao Formation of Xinbei Oilfield have the same burial depth,the resistivity of the oil and water layers varies greatly,A large number of low resistivity oil reservoirs have been discovered during production.The author uses technical means such as reservoir description,well logging interpretation,fluid and rock mineral analysis and testing to explore,discussed the influencing factors and reasons of low resistance oil layers.The main influencing factor of these low resistivity reservoirs is the infiltration of shallow seawater on the surface caused by faults,caused by the increase in mineralization degree of post formation water;Secondly,the shale content,rock skeleton particles and clay minerals of rocks deposited in meandering river;The low resistivity of individual well layers is also related to the thickness of oil layers,reservoir height,rock wettability,and special conductive minerals.
