Description
Technical field
The invention belongs to the applied technical fields of xanthan gum, and in particular to a kind of preparation method of liquid xanthan gum.
Background technique
Xanthan gum (Xanthan Gum) is that integrate emulsification, thickening, the microorganism of suspending stabilized superior performance high
Molecular polysaccharide.Since it is in polyanion state in aqueous solution, can be dissolved in hot water or cold water；And its conformation is also
It is diversified, it can express different characteristics at different conditions, there is unique physicochemical property, therefore in food, medicine, stone
Multiple industries such as oily industry and cosmetics, are widely used.However existing xanthan gum is solid powder substance, is made
It is long with dissolution time in the process, it is easy to produce conglomeration, operation is relatively complicated, and the scene for being not easy to be well adapted for oil drilling is answered
With also resulting in the problems such as recovery ratio recovered the oil in application process is low in this way.Therefore these problems are directed to, we are badly in need of developing one
Kind of liquid xanthan gum, with its dissolution sufficiently, without flake, temperature tolerance is good, the strong excellent performance of suspending power, using oil as carrier, more
It is mixed with well-drilling waste water, rejected well drilling liquid and drilling cuttings etc. well, is applied to drilling fluid, to solve the problems, such as in drilling well, improved and bore
Well efficiency.
The improvement that Many researchers all carry out different modes to xanthan gum at present is explored, to overcome some of itself to lack
It falls into, improves application.Chinese patent literature CN106833562A discloses a kind of xanthan gum liquid dispersion and preparation method thereof:
When using xanthan gum liquid dispersion, it is mixed with water, xanthan gum can rapid dispersion in water, it is existing that conglomeration will not be generated
As, the time of configuration xanthan gum solution is significantly shortened, it is convenient and efficient；And fugitive dust will not be led to the problem of, pollution-free, healthy ring
It protects.The preparation method process of this xanthan gum liquid dispersion is short, at low cost, efficient quick.In addition, liquid xanthan gum is probed into selection
To a variety of brills such as diesel oil-clear water system, crude oil-polymer drilling fluid system and crude oil-sulphonated polymer mud oil-in-water drilling fluids
The influence of well liquid system performance, prepares liquid xanthan gum polysulfonate oil-in-water drilling fluid system formulation, which compares
Good, site construction technology is relatively simple, and has heatproof, antiacid alkali, excellent tackifying, and play certain filtrate reducing
With good compatibility.Deep-well and ultradeep well downhole formation situation are complicated at present, and bottom hole temperature (BHT) is high, therefore are suitble to yellow using liquid
Virgin rubber handles drilling fluid.Liquid xanthan gum is widely used, but the application in China Petroleum also needs more, deeper time
Exploration and research (normal Gansu Province is tight, liquid xanthan gum oil-in-water drilling fluid research, mineral exploration engineering；2015,42(8): 6-12).
Chinese patent literature CN101270166B discloses a kind of preparation method of liquid xanthan gum.Utilize xanthan gum itself
Emulsibility, xanthan gum solid matter is added to prepare liquid xanthan gum in the mixture of both diesel oil and paraffin oil.
This liquid xanthan gum stability is good, and simple process, easy to operate, and can solve ordinary xanthan gums cannot be directly used to petroleum drilling
The problem of oil-base mud, is with a wide range of applications in well.
Although many documents all do improvement to xanthan gum and probe into, to achieve the purpose that Properties of Optimization, expand application range,
But still there are many problems in the liquid xanthan gum of improvement, as stability is poor, poor fluidity etc. deficiency.
