Abstract:The
chemical structure of coal has an important influence on coalbed
methane mining. Through Fourier transform infrared (FTIR) and Raman
analysis of coal samples after coupling treatment of temperature,
gas, and viscoelastic surfactant fracturing fluid (VES), we studied
the evolution law of coal chemical structure. It was determined that
the functional groups of coal decreased by approximately 30% with
increasing temperature, showing an obvious temperature sensitivity.
The VES fracturing fluids can destroy the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
