Study on Preparation and Stability of Fluorescent Functional Microspheres
Bohai Oilfield has formed a number of Bohai characteristics of Bohai driving technology,such as microsphere driving control,graded combination deep section control,online combined driving control,etc.,through the accurate detection of the output liquid medium driving control system,the accuracy of dynamic adjustment of the driving process can be further improved,and the accuracy of multi-round scheme design can be improved.However,at present,limited by the limitations of microsphere materials and detection methods,it is difficult to achieve the accurate detection of microsphere flooding liquid.In order to solve this problem,functional flooded microspheres were prepared by adding fluorescent quantum dots in the process of preparing functional modulation microspheres,and then mixing and adsorbing with shell monomer water and liquid,and their stability was analyzed.The results showed that the prepared functional flooded microspheres had good fluorescence characteristics and showed good stability with the changes of aging temperature,aging time and simulated water mineralization.
