摘　　要：过套管测井技术在剩余油饱和度评价、水淹程度评价、漏失油气层识别等方面具有独特地应用,分别选取塔河油田利用过套管测井技术识别薄互层;大庆油田水淹程度评价、长庆油田低渗透油层及新疆油田砂砾岩油层,来论述过套管测井技术应用。结果表明:利用过套管技术可以有效地寻找薄或差油气层,定性地反应油气层水淹程度,对于油气生产具有重要意义。但是过套管电阻率测井受到储层非均质性、低阻油层、地层水矿化度、地表结蜡等因素影响,从而一定程度上降低了过套管电阻率测井效果可靠性,因此在使用过套管电阻率测井过程中,应当注意这些问题。Casing logging technology has unique applications in residual oil saturation evaluation,flooding degree evaluation,leakage oil and gas reservoir identification,etc.,and the Tahe Oilfield is selected to identify thin interbeds by casing logging technology.The evaluation of theflooding degree of Daqing Oilfield and the application of casing logging technology were discussed.The results show that the casing technology can effectivelyfind thin or poor oil and gas reservoirs,and qualitatively reflect theflooding degree of oil and gas layers,which is of great significance for oil and gas production.
