摘　　要：依据大量的岩心、录井、测井、试油和分析化验资料,对春光油田春10井区沙湾组的油水层识别进行了研究;为了定性识别油层,研究了储层四性特征和测井参数特征;应用岩心刻度测井技术,制作了孔隙度解释图版,并进行了公式回归。应用经验公式法和压汞法相结合综合确定的含油饱和度更符合本地区的特点,在此基础上,建立了适合本井区的油水层识别图版,提高了测井储层参数解释精度。Based on the large number of cores,logging,oil testing and analytical testing data,the oil-water layer identification of Shawan formation from Chun-10 well in Chunguang oilfield has been studied.In order to realize qualitative identification of oil reservoirs,the four properties and logging parameters characteristics have been studied.By applying core scale logging technology,the porosity interpretation chart has been established.In combination with formulas regression,experience formula and mercury injection methods,the oil saturation more suitable for this area has been determined.On the basis of this,oil-water layer identification plate suitable for this well area has been established and it will enhance the logging interpretation accuracy of reservoir parameters.
