Design of visual flow simulation experiment system for chemical working fluid in unconventional oil and gas fields

Combined with unconventional oil and gas field development technology and based on microfluidic technology, a set of unconventional oil and gas field chemical working fluid flow simulation experiment system was designed, and the unconventional oil and gas field chemical working fluid micro-flow simulation experiment device and method were established, which realized the visualization and quantitative characterization of chemical working fluid flow characteristics under the condition of reservoir structure, and can be used as an important auxiliary means to study the flow characteristics of chemical working fluid, catalyst migration and phase transformation of oil and gas under the condition of unconventional reservoir structure. The experimental design is conducive to stimulating students' enthusiasm for learning and research, broadening their interdisciplinary research vision, and cultivating their comprehensive analysis and application practice ability. It also helps students form the ability to combine theory with engineering practice to solve practical engineering problems on the site.
