摘　　要：同位素吸水剖面在油田开发中扮演着重要的角色,对于优化油田开发策略、保持油田稳定生产和提高开采效率等都具有重要的作用,对于油田或者区块的注水井开发状况及开发形势进行综合评价,从而为油田的进一步开发和生产提供决策依据。针对同位素测井工艺现状,从测井速度、管柱、井内异物、注水压力、扰动现象等方面对原始曲线进行深入研究,着重分析了同位素吸水剖面测井解释过程中的疑点和难点,提高了对资料的认识程度,能很好指导解释实践。Isotope water intake profile plays an important role in oilfield development,which plays an important role in optimizing oilfield development strategy,maintaining stable production and improving exploitation efficiency.It can evaluate the development status and development situation of injection wells in oilfields or blocks,so as to provide decision-making basis for further development and production of oilfields.In view of the current status of isotope logging technology,this paper studies the original curve from many aspects,such as logging velocity,pipe string,foreign body in well,water injection pressure and disturbance phenomenon,and emphatically analyzes the doubts and difficulties in the interpretation of isotope water injection profile logging,which improves the understanding of data and can guide interpretation practice.
