Summary
l DOC-S61S is a high-temperature-resistant spacer, which is composed of a variety of temperature-resistant polymers and surfactants.
l DOC-S61S has strong suspension and good compatibility. It can effectively isolate drilling fluid and cement slurry when displacing drilling fluid, and prevent mixing between them.
l DOC-S61S has a wide weighting range (from 1.0g/cm3 to 2.2g/cm3), and the prepared spacer is stationary for 24h with a density difference of less than 0.10g/cm3.
l DOC-S61S can change the interface from oleophilic to hydrophilic.
