Xanthan Gum 80 mesh Oil drilling grade cas 11138-66-2

1. Excellent rheological properties of drilling fluid
Petroleum-grade xanthan gum is a high-molecular-weight biopolymer with extremely strong viscosity-increasing and shear-thickening capabilities. A very low dosage can significantly increase the viscosity and shear force of the drilling fluid, preventing well wall collapse, stuck pipe and other downhole accidents, and perfectly meeting the rheological requirements of drilling operations.
2. Outstanding salt resistance, temperature resistance and anti-pollution performance
It can maintain a stable viscosity-increasing effect in high-salt (saturated brine) and high-calcium-magnesium-ion environments, and its salt resistance far exceeds that of common hydroxyethyl cellulose and other polymers. It performs stably in complex geological conditions (such as salt mud layers, deep wells, and ultra-deep wells).
3. Excellent environmental compliance and compatibility
Produced by biological fermentation technology, it can be completely biodegradable, non-toxic and harmless, and complies with global environmental protection drilling fluid standards.
4. High cost-effectiveness and versatility
It has excellent solubility at 80 mesh particle size, can dissolve quickly in cold water, has a fast dissolution speed, no fish eyes or lumps, and has high efficiency for on-site liquid preparation.

1. Oil and gas drilling operations
As the core thickening and cutting agent, and the anti-filtering agent for water-based drilling fluids / muds, it is used in various drilling operations such as conventional oil and gas wells, deep wells, ultra-deep wells, horizontal wells and shale gas wells.
2. Completion and well repair operations
It is used for thickening the completion fluid and well repair fluid to enhance the suspension ability of the working fluid, prevent the sedimentation of solid particles, and ensure the smooth progress of operations such as pipe string lowering and perforation during well completion.
3. Other oilfield-related scenarios
It is used for profile adjustment and water shutoff, as well as in the fracturing fluid system. As a thickening agent, it increases the viscosity of the fracturing fluid, carries the support particles, and optimizes the fracturing effect;
It is also used for oilfield wastewater treatment, as a flocculation aid to assist in sludge dewatering and improve the efficiency of wastewater treatment.
