Product function

1. Strong inhibition,can effectively control the hydration,expansion and dispersion of mud shale and drilling cuttings, inhibit formation grouting, and stabilize the borehole wall.

2. Strong salt and calcium resistance,suitable for fresh water,brine,saturated brine and seawater drilling and completion fluids.

3.Small dosage can effectively control water loss and improve the quality of mud cake.

4.With good compatibility with treatment agent,it can be used in various water-based drilling and completion fluids.

5. Non-toxic,conducive to environmental protection.

6. With good thermal stability,it can be used in deep and ultra-deep wells.
