Abstract

The present invention belongs to the preparation of xanthan gum, in particular to a method for preparing liquid xanthan gum. By the emulsifying property of the xanthan gum and under the function of other emulsifiers, in the method, a xanthan gum product is added into diesel oil, paraffin oil or the mixture of the diesel oil and the paraffin oil in a solid-liquid mixing device to prepare the liquidxanthan gum with good stability. The present invention resolves the problems that the prior art cannot be directly used for oil-base mud in petroleum-drilling wells, and the petroleum extraction rateis low in the process of application; the stability of the prepared liquid xanthan gum is good, and the present invention resolves the problem that the ordinary xanthan gum cannot be directly used for oil-base mud in petroleum-drilling wells, and increases the petroleum extraction rate by more than 20 percent; the present invention has the advantages of simple technique, easy operation, low production cost, etc.

Description

technical field [0001] The invention belongs to the preparation of xanthan gum, in particular to a preparation method of liquid xanthan gum. Background technique [0002] At present, because the existing xanthan gum is a solid product, it cannot be directly used in oil-based mud in oil drilling, resulting in the problem of low oil recovery in the application process; in addition, the existing technology still has a relatively cumbersome use process and is not easy to operate And other issues.
