In drilling applications,has the following characteristics :higher is the water loss control ,cost effective loss reduction taking into account agent,the formation of mud-cake quality,tough,have a high salt resistance ,temperature resistance ,has a good non-Newtonian fluid performance ,good control of slurry rheology. PAC-containing mud,can form a thin wall kin, low permeability filter cake ,so to reduce waterloss,thereby reducing water loss due to mud caused by necking ,callapse,fall block and so on .Drilling mud and other suspended dispersion like the existence of a certain period ,be able to join the PAC to extend the life span ,especially those cotaining dissolved salt mud ,the more significant.
