Features:

1. Has good temperature resistance, salt and calcium resistance and shear resistance;

2. Has good dispersion performance and heat conduction and heat dissipation performance;

3. Strong resistance to external environmental interference and good chemical stability;

4. Good salt resistance, high sensitivity to high-priced ions and excellent thermal stability;

5. Does not corrode drilling tools and ground circulation equipment;

6. It can be used in deep wells, ultra-deep wells and high salinity brines. It can also be used for low solids and solid phase completion fluids.

7. It is suitable for different water quality. It can effectively control the fluid loss in fresh water, salt water and seawater drilling fluid. The filter cake has good quality and good compatibility. It can be combined with various treatment agents and is suitable for various water-based drilling fluid systems. .

use:

Used in drilling operations, the amount of fresh water slurry is generally 0.3-1%, and the amount of brine slurry is 1-2%.

It can be directly added to the circulating well slurry and can also be formulated into a glue solution.
