Abstract
The invention belongs to the field of preparation of microbiological polysaccharide solution, and especially relates to a preparation method of a paste welan gum. The preparation method comprises the following steps: inoculating sphingomonas paucimobilis (CGMCC No.1561) to a sterile fermentation culture medium, which contains a carbon source, a nitrogen source, inorganic salts, and water; then carrying out extraction and solid-liquid separation, and finally manufacturing the paste welan gum. In the prior art, the welan gum powder cannot be directly applied to oil-based slurry in petroleum drilling wells and the operation safety of welan gum powder is bad. The provided paste welan gum solves the problems mentioned above. The preparation method is simple. The paste welan gum is suitable for industrial production, transportation and preservation. The stability of the paste welan gum is good. The paste welan gum can be rapidly and evenly mixed with oil-based slurry.
