Summary
OBC-S25S is a type of medium-low temperature spacer, and is compounded by a variety of polymers and synergistic materials.
OBC-S25S has strong suspension and good compatibility. It can effectively isolate drilling fluid and cement slurry when replacing drilling fluid, and prevent production of mixed slurry between drilling fluid and cement slurry.
OBC-S25S has a wide weighting range (from 1.0g/cm3 to 2.2g/cm3). The upper and lower density difference is lees than 0.10g/cm3 after the spacer is still for 24 hours.
