WELAN GUM is a Fine powder, rapid hydration, biopolymer produced by fermentation. WELAN GUM powder can be used as viscosity rheology agent in oilfield drilling fluids, lost circulation fluids, grouting materials and other systems.
1.In the food industry, welan gum can be evaluated in the processing of baked goods, dairy products, juices, milk drinks, sugar coatings, frostings, jams, meat products and various desserts. 2.In the petroleum industry, welan gum can be used to prepare drilling mud to maintain the viscosity of water-based drilling fluid and control its rheological properties. Welan gum is also a new type of oil-displacing agent, which is used for tertiary oil recovery of oil wells. When welan gum is prepared into an aqueous solution of suitable concentration and injected into the well, it is pressed into the oil layer to displace oil, which can greatly increase the oil recovery rate. In addition, welan gum can also be used as a flow improver in well completion, well workover, formation fracturing and heavy oil transportation. 3. Welan gum can be widely used in cement and concrete. Welan gum powder can enhance the water retention of mud. When Welan gum is used as a water retention agent, it does not require the use of dispersants like other additives. Welan gum can increase the plasticity, suspension capacity, air content, anti-sag ability, flow characteristics and resistance to water loss of cement. These improved characteristics remain unchanged when the temperature increases. Compared with other additives, lower concentrations of welan gum can achieve good results.
