多色硅基量子点示踪剂的制备与性能评价
Preparation and performance evaluation of multi-color silicon-based quantum dot tracers
针对水平井产出剖面监测需求和传统示踪剂技术的局限性,通过水热法研发了高性能多色硅基量子点示踪剂,采用TEM、XPS、TGA等表征手段对材料进行结构分析,并评价了不同油藏条件下多色硅基量子点示踪剂的性能。结果表明,多色硅基量子点示踪剂粒径范围在6~8 nm之间;TGA表征结果说明多色硅基量子点示踪剂具有较好的热稳定性,适应在高温下应用;并且在矿化度15 000 mg/L、温度80℃,pH值在弱酸至弱碱性范围内可以保持良好的荧光强度和分散稳定性。
High-performance multi-color silicon-based quantum dot tracers are developed via a hydrothermal method to meet the demand from production profile monitoring in horizontal wells,and overcome the limitations of traditional tracer technologies.The structure of the tracers materials is analyzed by using characterization techniques such as transmission electron microscope (TEM),X-ray photoelectron spectroscopy (XPS),thermogravimetric analysis (TGA),etc.The performance of the prepared tracers is evaluated under different oil reservoir conditions.The findings indicate that the particle size of the prepared tracers ranges from 6 nm to 8 nm.TGA characterization results demonstrate that the tracers possess good thermal stability,making them suitable for applications under high-temperature conditions.They can maintain excellent fluorescence intensity and dispersion stability under a salinity of 15 000 mg/L,a temperature of 80℃,and a pH ranging from weak acidity to weak alkalinity.
