摘　　要：同位素示踪注水剖面测井的理论基础是同位素示踪测量技术。测井实践表明,同位素示踪污染广泛存在。同位素污染校正是改善和提高注水剖面测井解释成果的重要技术,研究各种井况下污染类型识别、污染校正系数等是保证污染校正准确的基础。研究表明,目前各油田普遍使用的常规经验校正系数,仅对特殊的井况条件适用,必须根据现场实际研究相应的校正方法才能更好满足注水剖面监测需要。WATCH平台提供了完善的注水剖面污染校正技术。Isotopic trace injection profile logging theory is based on isotopic tracer measurement technology. This logging practice shows that isotopic contamination widely exists. Contamination correct technique is important in improving the injection profile interpretation result. The contamination correct coefficient is calculated for various downhole environments. The different contamination types are i-dentified to ensure the accurate correction. It is shown that the common expertise coefficient used in many oilfields is adaptable to some special wellbore situations. In order to meet the requirements of injection profile monitoring, we must have got corresponding correct method based on different logging conditions. The perfect injection profile contamination correct technology is provided by WATCH platform.
