Summary
DOC-W21L is made up of several kinds of surfactants and has good cleaning effect, effective infiltration, ooze stripping function on water base drilling fluid. It has good compatibility with cement slurry and will not cause cement slurry thixotropic and flocculation. It can improve the hydrophilicity of casing interface and formation interface, achieve interface wettability alteration, and enhance the bond strength of slurry cement paste interface and improve the cementing quality.
Usage range
Temperature: 30~180℃ (BHCT).
Recommend dosage：6.0~10.0% (BWOW).
Recommend to check its compatibility with cement slurry before using it.
