PRODUCTS TECHNICAL DATA
PRODUCT NAME :HTHP fluid loss control agent,ME-HDD
COMPOSITION / INFORMATION ON INGREDIENTS AND APPLICATIONS
HTHP fluid loss control agent,ME-HDD is a Hydroxyl copolymer powder, for high density & high temperature resistant WBM drilling fluids fluid loss and shale control .
Through zwitterionic exchange and hydroxyl action of absorption on the surface and end face of clay respectively, achieve strong inhibition on the formation, avoid the phenomenon of water and clay stratification, and connect the broken small pieces, so that the well wall shale does not easily peel off, the drilling cuttings do not easily hydrate or expand, reduce the filtration of calcium and magnesium bearing blocks, clean the wellbore and other functions. In the saturated salt water drilling fluid, the fluid loss reduction effect is remarkable, the temperature resistance ability is 180 ℃, and the high temperature stability is good. Compared with other similar products, it does not increase viscosity, but is resistant for saturated brines.
By application: In saturated salt water adding amount of 1.5% of HTHP fluid loss control agent,ME-HDD; at normal temperature, fluid loss is decreased from 99 ml to 7 ml; After aging at 150℃ for 16h, the filtration loss is decreased from 109mL to less than 10mL.
Recommended dosage: add directly to mud for 1.5%.
Appearance : free flowing gray powder
Moisture % ≤ 10.0
