Drilling fluid emulsion filtrate reducer

Drilling fluid emulsion filtrate reducer

1、 Application field: during drilling, the drilling fluid filtration is large, which is easy to cause hydration expansion and collapse of shale, resulting in wellbore instability; Drilling fluid and filtrate invade the formation, causing clay expansion and well diameter reduction, which is easy to cause sticking. The filtrate reducer can reduce the filtration of drilling fluid through the mechanism of hydration film thickening, viscosity increasing and hole plugging, so as to ensure the rapid, high-quality and safe drilling. 2、 Product index project index appearance viscous liquid viscosity, MPA • s ≥ 100 density, mg / L ≥ 1.01, pH ≥ 6.5 flash point, ℃≥ 100 solid content,% ≥ 35 dissolution time, min
