Description

Flocculant:Can flocculant drilling fluid cuttings and clay.
Lubrication:Then product will adhere to the surface of metal or clay particles and form a liquid film,cake's friction coefficient and bring down mine accident rate.
Plugging effect:Affected by ions of Al+,Fe+,Ca+,cross-linking reaction could occur.And part of the high-molecular compound will be transferred from linear type into body type.It is insoluble in water,which adheres to the wall of the well and close up the stratum gap and prevent the leakage of drilling fluid.
Filtration reducing effect:The higher the product's hydrolysis is,the more hydration groups are there on its molecular chain and the better hydration effect it will be.And it will change from flocculant into filtration reducer.
In drilling fluid,the product can form a net frame space with clay particles.It's effective viscosity drops along with the increase of shear thinning rate.It's shear thinning effect is good.
