摘　　要：随着油田勘探开发程度加深,动静态资料不断增多以及技术的进步,有必要对原电性标准及油层下限进行界定。应用老井复查评价技术,结合现代精细油藏描述,充分利用录井、测井等资料对原认为是“干层”、“水层”的井层进行复查评价,使有效资源得到再利用,老区产量递减得到减缓的同时,也增加了含油面积及可动用储量。该技术具有成本低、风险低、见效快的特点,获得了明显的社会效益和经济效益。With the growth of technology,it is required to define the original electrical property standard and the lower limit of oil layer with the deepening of oilfield exploration and development,and the continuous increase of static and dynamic data. The old well reexamination and evaluation technology are combined with modern fine reservoir description,and the well layers originally referred to as“dry layers”and“water layers”are reexamined and evaluated using mud logging,logging,and other data,allowing the effective resources to be reused and the decline of production in the old area to be slowed. The oil-bearing area and recoverable reserves have both been enhanced at the same time.The technology is low-cost,low-risk,and has a speedy effect,and it has brought significant social and economic benefits.
