Main ingredients
The temperature resistance of lotion polymer for drilling fluid is 165 ℃, which is an inverse lotion polymer composed of acrylamide or alkyl acrylamide, acrylic acid, sulfonic acid and its derivatives.
Main component molecular structure [C2H3CONH2]m[C2H3COONa]n[C7H13NO4S]x
Nature and Use
The product is a light colored emulsion with a light oil odor, used as a non dispersed low viscosity filter loss reducer for water-based drilling fluids. Can control the filtration rate of drilling fluid and improve the lubrication performance of drilling fluid.

Product features
1. The viscosity effect is small, the filtration loss reduction ability is strong, and it can maintain the non dispersibility of polymer drilling fluid.
2. Salt resistant, with strong resistance to calcium and magnesium, it can be used in freshwater, saline, and saturated saline drilling fluid systems.
3. Compared with solid polymers, it has good dispersibility, fast dissolution rate, and high effectiveness. Not in conflict with the use of fixed control equipment, with high cost-effectiveness and low cost.
4. Easy to use, fast, and easy to supplement and maintain at any time. No dust pollution and the hassle of preparing treatment agent solutions are beneficial for improving the hygiene and physical health of workers, making it more environmentally friendly
Usage
It can be prepared into an aqueous solution for use or directly added to the drilling fluid circulation system. When adding directly, attention should be paid to the feeding speed, and a uniform slow addition or intermittent addition method should be used.
Recommended dosage: (volume ratio)
Freshwater drilling fluid: 0.5-0.8%, saline and saturated saline drilling fluid: 0.5-1.0%.
