摘要
根据近几年来孤东油田低阻油藏勘探开发的实例,从沉积特征、封盖条件、运移通道、圈闭类型介绍了低阻油藏的形成条件,通过总结孤东油田低阻油藏的认识经验,建立了类似孤东油田低阻油层的识别标志,从滚动勘探及老井补孔两方面介绍了挖潜方法。同时建议测井技术人员从测井解释方面,运用侧向电阻率测井反演技术、测井曲线高分辨率处理技术,建立一套针对低阻油藏储层的测井评价标准,从而正确评价新井低阻储油层。
Based on exploration and production practices in the low resistivity reservoirs in Gudong oilfield in recent years, the forming conditions of low resistivity reservoirs are introduced in respects of sedimentary features, sealing conditions, migration pathways and trap types. Identification criteria for low resistivity oil layers are established based on the knowledge acquired in study of the low resistivity reservoirs in Gudong oilfield, and production potential tapping methods are presented with respects to progressive exploration and production and additional perforation in old wells. It is proposed that a set of logging e-valuation criteria for low resistivity reservoirs should be established by using lateral resistivity logging inversion technologies and high resolution logging processing technologies, thus low resistivity oil layers in new wells can be correctly evaluated.
