Potassium polyacrylate, a non-toxic and non-corrosive wellbore stabilizer for drilling fluids, is readily soluble in water. This product exhibits excellent inhibition of shale and drill cuttings dispersion, while also offering benefits such as reduced fluid loss, improved flow characteristics, and enhanced lubricity. It effectively suppresses formation mud generation and is compatible with a wide variety of treatment agents, making it a versatile and highly desirable wellbore stabilizer. The product appears as a white or pale yellow powder.

Product Use

Shear-thinning and anti-sloughing flocculation for non-dispersive, low-solids muds and polymer systems used in underground wells.

1. This product is a non-toxic, non-corrosive wellbore stabilizer with a wide range of applications. It effectively inhibits the dispersion of shale and drill cuttings, while also reducing fluid loss, improving flow characteristics, and enhancing lubricity. It can efficiently suppress formation fluid generation and is compatible with various treatment agents. It improves the rheological properties of drilling fluids, effectively coats drill cuttings, and effectively suppresses formation fluid generation. The presence of potassium ions helps prevent hydration and slaking of both soft shales and brittle-hard shales, thereby stabilizing the wellbore.

2. It has good compatibility with other treatment agents and can be used in both non-dispersed and dispersed drilling fluid systems.

3. Strong temperature resistance (≥ 180 ℃).
