Petroleum drilling grade xanthan gum is an efficient, environmentally friendly oil drilling mud additive, suitable for temperatures (≥94°C),
The acid, alkali, and salt have excellent tolerance, which can significantly improve the permeability of the mud and the ability to suspend solid matter, stabilize the well wall, and reduce damage to the oil reservoir, thus significantly improving the efficiency of drilling, workover, and completion work. This product has good temperature and salt resistance and good shear dilution and particle suspension effects. Therefore, it is an ideal mud additive for offshore drilling. It can remain stable for a long time under saturated salt water and a temperature of 85°C. Therefore, it is an ideal oil displacing agent in high-temperature and high-salt oil fields. Xanthan gum is a biological gum that integrates thickening, suspension, emulsification and stabilization. Xanthan gum has the general properties of long-chain polymers, but it contains more functional groups than ordinary polymers and will show poor performance under specific conditions. Its conformation in aqueous solution is diverse and it exhibits different properties under different conditions.

Suspending and emulsifying properties

Xanthan gum has a good suspending effect on insoluble solids and oil droplets. Xanthan gum sol molecules can form super-bonded ribbon-shaped helical copolymers, forming a fragile glue-like network structure, so they can support the shape of solid particles, droplets and bubbles, showing strong emulsion stabilization and high suspension ability.

water soluble

Xanthan gum can dissolve quickly in water and has good water solubility. Especially it can also be dissolved in cold water, which can save the complicated processing process and is easy to use. However, due to its hydrophilicity, if a small amount of water is added directly and the stirring is insufficient, the outer layer will absorb water and swell into micelles, which will prevent water from entering the inner layer and affect the performance of the function. Therefore, care must be taken to use it correctly. Mix xanthan gum dry powder or dry powder accessories such as salt and sugar evenly, then slowly add it to the stirring water to make a solution for use.
