Application of Xanthan Gum in Petroleum Industry
A huge market for xanthan gum is petroleum industry. In the performance of Viscosity, thickening, salt resistance and contamination resistance, xanthan gum is far better than other polymer; especially in the well drilling of sea, beach, high halide layer and permafrost layer, xanthan gum has remarkable effect in sludge treatment, completion fluid, and tertiary oil recovery, and has significant function for accelerating drilling speed, preventing the well collapse, protecting oil and gas fields, preventing the blowout, enhancing oil recovery rate substantially, etc. As a kind of ideal additive, this product has very favorable development prospect.
Drilling fluid is the working fluid applied in drilling process. During the drilling process, drilling fluid acts important function. People usually refer it to as “blood of drilling”. xanthan gum is one of its main components. Its functions are adding viscosity and shearing force, improving the suspending power of drilling fluid which is essential in using functions of the drilling fluid.
2.Oil exploitation industry
Since the xanthan gum is with good viscosity, rheological property, water-solubility, and chemical stability and also with strong performance for mechanical degradation resistance, it can be used as displacing agent of oilfield exploitation. Many kinds of polymer can be used as mobility control agent in oil exploitation. Among these kinds of agent, xanthan gum is identified as the agent with most utilization potentiality. Xanthan gum contains many essential conditions required for improving oil recovery rate.
