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.
1.Drilling Industry
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.
Matters needing attention
It should be stored
under environment temperature, airtight, dry conditions.
