in this paper, through the analysis of the existing problems and influencing factors in the application of historical data of injection profile, continuous correlation logging technology of injection well, electromagnetic flow and tracer correlation logging technology are applied to solve the problems of overflow and contamination of isotope profile test in low injection wells. In general injection wells, the current collecting electromagnetic flow logging technology is applied; in stratified injection wells with different water injection intensity, oxygen activation logging, isotope water injection profile logging, tracer correlation logging and other logging technologies are used to combine logging according to the injection volume and string structure testing instrument scope, so as to eliminate the contamination effect and improve the accuracy of interval water injection profile test.
