Abstract:An excellent flushing efficiency evaluation device is
indispensable
for studying the cementing flushing fluid. However, the existing flushing
efficiency evaluation device cannot simulate the formation and flushing
process of the downhole mud cake. Therefore, this paper proposes a
novel flushing efficiency evaluation device that can simulate the
formation and flushing of downhole mud cakes. The rotational speed
of the device during flushing and the rotor’s diameter is deduced
based on the principle of equal wal… 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.
