摘　　要：对处于开发中后期的油田而言,因受地层条件、射孔完井工艺、套管技术状况、井眼状况及同位素特性等的影响,造成注入剖面测井解释精度降低,大大降低了对注入井注入剖面评价的准确程度。如何克服各种测井方法的局限性成为吸水剖面资料解释的关键所在。示踪相关流量测井是近年来推出的一种新的吸水剖面测井方法,该技术要求示踪剂配制液达到很好的悬浮性、流动性、携带型和稳定性,以保证示踪剂无论是点射还是连续释放都能在注水井中均匀不沉降、扩散小、不沾污油管、套管和井下工具,可以直观地反映吸水剖面资料。本文剖析了示踪相关流量吸水剖面测井原理,并就其测井工艺及测井资料解释方法进行了分析研究。As for the oilfield exploration in the mid--to--late period, due to the ground con- ditions, perforation completion technology, casing technical conditions, borehole conditions and isotopic characteristics and so on, the injection profile logging interpretation accuracy is reduced, which has a great effect on the correct evaluation of the well injection profile. How to overcome the limitations of the various logging methods becomes the key to the da- ta interpretation for water injection profile. Tracer relative flow rate log is a recently devel- oped new water injection profile logging method. This technology requires the tracer prepa-ration liquid to achieve good suspension property, fluidity, portable property and stability so as to ensure no matter whether the tracers in water injection well spot or continuously release, they will not settle down uniformly, not scatter much, not contaminate tubing, casing or the downhole tool. They can directly show the water injection profile data. This paper describes the principle of the tracer correlation flow rate injection profile logging, and analyzes the well logging technology and interpretation method of the logging data.
