Application:
The product can be used in fresh water, salt water, and sea water drilling fluid systems. It has functions of reducing filtration loss, increasing the viscosity of drilling fluid and coating shale. Thus, shale expansion can be suppressed and borehole collapse can be prevented. And it has many other capabilities, such as better colloidal stability and salt tolerance, resistance to calcium and magnesium and other high valence metal ions.
