Problems solved by technology

Some papers and books mention that physical mixing of konjac polysaccharides and plant fiber etherified cellulose is no longer a purely physical mixed solution viscosity in terms of viscosity effect, which can be explained as plant fiber etherified cellulose will destroy konjac The hydrogen bond in the polysaccharide molecule and the binding force with water lead to the viscosity-reducing effect of the two mixtures, and the etherified cellulose of plant fiber and konjac polysaccharide can form a hydrophobic association area, but this structure is not stable enough, and it can only be relieved at high temperature. The speed of carbon chain breakage, the loss of association, and the temperature resistance need to be enhanced. Based on this, the plant fiber cellulose and polysaccharides can be combined through chemical reactions

Abstract

The invention relates to the technical field of oil field drilling fluid treating agents, and discloses plant fiber modified fungus powder and a preparation method thereof, the preparation method comprises the following three steps: (1) pretreatment of plant fibers: adding a swelling agent into plant fiber powder to fully swell; (2) pre-treating the fungus powder: adding a strong oxidizing substance into the fungus powder for reaction; and (3) preparing the plant fiber modified fungus powder: adding the pretreated plant fiber into a reaction solvent, heating, adding the pretreated fungus powder, and adding a catalyst. The plant fiber modified fungus powder is prepared by reaction of pretreated plant cellulose and oxidized fungus powder polysaccharide, not only has a cellulose rigid structure, but also can introduce fungus powder polysaccharide with a plurality of active functional groups, has better properties of temperature resistance, salt tolerance, lubrication, tackifying, filtrate loss reduction and the like, and can be used for preparing the plant fiber modified fungus powder. The material can be used as an excellent environment-friendly raw material in the field of drilling

Description

technical field [0001] The invention relates to the technical field of oilfield drilling fluid treatment agents, in particular to plant fiber modified fungus powder and a preparation method thereof. Background technique [0002] In recent years, a large number of polymer pollutants have entered the ecosystem, which has brought great challenges to the ecological environment. For this reason, renewable natural raw materials continue to receive attention. The inventor found that cellulose is a natural and environmentally friendly material that has active functional groups but is insoluble in water and most organic solvents by consulting a large amount of information. These fiber materials are rich in sources, low in price, and have unique chemical compositions. Feasibility of recycled materials. Cellulose fibers are mainly composed of cellulose, hemicellulose, lignin, etc., and have a large number of active hydroxyl groups. Intramolecular hydrogen bonds and intermolecular hyd...
