摘　　要：滩坝砂储层是油田开发中常见的低渗透油藏类型,储层具有垂向和平面非均质性强,物性变化大等特点。早期油田勘探开发技术单一,滩坝砂储层勘探潜力认识不足,许多潜力区没有发现。本文结合开发数据和测录井等试验资料,在XX油田A1区开展综合研究,通过研究区储层岩石物性资料数据、常规测井资料、成像资料等建立滩坝砂储层测井判别识别评价技术,对老区滩坝砂油藏进行二次解释,进一步识别潜力储层,为老区滩坝砂储层增产稳产提供了技术支撑。Beach bar sand reservoir is a common type of low permeability reservoir in oilfield development.The reservoir has the characteristics of strong vertical and plane heterogeneity and large changes in physical properties.The exploration and development technology of early oil fields was single,the exploration potential of beach bar sand reservoir was not recognized,and many potential areas were not found.Combined with development data,logging and other test data,this paper carries out comprehensive research in block A1 of XX oilfield,establishes logging discrimination,identification and evaluation technology of beach bar sand reservoir through reservoir rock physical property data,conventional logging data and imaging data in the study area,carries out secondary interpretation of beach bar sand reservoir in the old area,and further identifies potential reservoirs,It provides technical support for increasing and stabilizing production of beach bar sand reservoir in the old area.
