Development and Application of Intelligent Polymer Tracer Loading Tool
In the conventional horizontal well segmented fracturing monitoring process,the use of liquid tracer has problems such as short monitoring cycle,large diffusion effect,and affecting testing accuracy.However,intel-ligent polymer tracer is a solid tracer with slow-release performance,which can meet the long-term monitoring needs of horizontal wells(monitoring period greater than 1 year).However,there is no matching tool in China that can be used with intelligent polymer tracer.Therefore,an intelligent polymer tracer loading tool is designed,which consists of anchor cards,protective covers,and connecting subs,which can be used together with the pro-duction string to realize the purpose of long-term monitoring.This article introduces the technology of intelligent polymer tracer,the design and manufacturing of loading tools,and explains the installation process and process flow of loading tools for production capacity profile monitoring,combined with the first application case in China.On site applications have shown that the loading tool has good stability performance and can meet the needs of in-telligent polymer tracer monitoring,filling the technical gap in this technology in China.
