Progress in Research and Application of Flushing Fluid Technology Both in China and Abroad

Abstract:

On the basis of a large number of relevant literatures and reports, the research and application progress of drilling fluid technology in recent years are summarized, which are introduced in two aspects: new slurry making material & mud treatment agent and new flushing fluid system; the former involving slurry material, strong inhibitor, high-temperature resistance treatment agent, plugging materials, nano processing agent and modified natural polymer treatment agents; the latter including a film-forming anti-collapse solid-free flushing liquid, double polymer collapse-preventing flushing liquid and a circulating foam washing liquid.

Key words:flushing fluid; slurry making material; mud treatment agent; geological drilling
