摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to methods of producing guar gum and use of this gum when processing an underground layer. The method of producing guar gum involves rolling unhulled guar fragments, grinding flake-like unhulled guar fragments to obtain powder of guar gum. The product is obtained using the method given above. The method of processing an underground layer drilled by a well shaft involves formation of processing fluid which contains an aqueous liquid and powder of guar gum containing at least 70 wt % resin material and at least 15 wt % hull material at feeding the processing fluid into the underground layer through the well shaft. The invention is developed in subclaims. ^ EFFECT: more efficient production of guar gum and use thereof. ^ 24 cl, 6 dwg |
