This product is a black powder with excellent fluid loss and filtration control properties, effectively improving mud cake quality and adjusting the rheology of drilling fluids. It is commonly used in deep well drilling fluids.
This product offers the following performance characteristics:
1. It forms a thin, tough mud cake, which reduces friction, enhances lubricity, and increases rotational speed.
2. It has a wide range of applications and can be used in various water-based drilling fluid systems, including freshwater, seawater, and 15% saline water. It is compatible with other drilling fluid additives. After adding this product, it significantly reduces fluid loss and filtration volume without affecting other properties.
3. This product is a free-flowing powder, non-toxic and harmless, easily soluble in water, and convenient to add. It can be added at any time during drilling operations.
