摘　　要：探讨了应用碳氧比测井资料确定水淹层剩余油饱和度及评价水淹层的方法,对碳氧比测井曲线进行了泥质、矿化度、套管及水泥环等影响校正.用新编制的碳氧比解释程序COA计算地层的剩余油饱和度、孔隙度、渗透率、产水率、地层水混合液矿化度等参数,从而对水淹地层进行综合评价.对三口井的碳氧比测井资料的实际处理结果表明.用COA程序可取得较好效果.This paper investigates the methods to determine the oil saturation of water flooded formation and the methods of correcting shale, salinity, cement thickness effects for C/O logs. A newly developed COA interpretation program was used to calculate saturation,porosity, permeability, water production rate and salinity of mixed formation water, and theflooded formation data from three wells were interpreted by using the COA program. Theresults are satisfactory.
