Polymer Reducer Viscosity XY-27
This product is white or faint yellow powder, which can effectively reduce the viscosity of the drilling fluid, and it is a kind of good viscosity reduction agent in polymer system.
Characteristics:
1. It has unique molecular structure and performance characteristics. And on the polymer molecular chain, it simultaneously possessed organic cationic group and anionic group. The introduction of organic cationic group enhances the adsorption strength and rate of XY-27 on the clay surface, and at the same time, neutralizes the clay surface charge, having strong inhibition capacity. Exist of large anionic group improves the viscosity reduction effect of XY-27. XY-27 is a treating agent integrated in efficient viscosity reduction and strong inhibition.
2. It solves the problem that existing anionic polymer with low molecular weight will weaken the inhibition of med system when reduced the viscosity. It can reduce the mud’s structural viscosity and water-hole viscosity, and effectively inhibit hydrating expansion of shale.
3. It can be compatible with all kinds of mud and treating agents. It can be used in non-disperse and disperse system as well as salt water mud, which is an ideal viscosity reduction agent for inhibition mud.
