Water-Proof Channelling Agent

Brief Introduction:

It can obviously increase the internal structure of cement slurry, shorten the static gelling transition time and avoid the shrinkage of cement.

BCG-400S is a kind of water-proof channeling agent for oil well cement, which is made up of inorganic material and organic material. It can obviously increase the internal structure of cement slurry, shorten the static gelling transition time and avoid the shrinkage of cement. The cement slurry can resist the occurrence of water channeling in different solidification stages of cement slurry, especially suitable for oil and gas well cementing where water channeling is easy to occur in adjustment wells.
