| titleOfInvention | An elastic cemented breathable material for preventing the instability of borehole wall and its preparation method |
| abstract | The invention discloses an elastic cemented and breathable material for preventing the instability of the borehole wall and a preparation method thereof. ~6.8 parts, 10-16 parts of wheat straw, 20-32 parts of dilute hydrochloric acid, and 0.1-0.15 parts of cellulase. During preparation, the wheat straw is first ground into wheat straw powder, then the wheat straw powder is mixed and soaked with dilute hydrochloric acid in container A, and cellulase and sterile water are mixed in container B to form cellulase liquid; Add liquid silica gel, curing agent and steel fiber to C, pour the dilute hydrochloric acid in container A, the treated wheat straw and the cellulase liquid in container B into stirring container C, stir and introduce compressed air, Finally, an elastic cemented breathable material is produced. It can reinforce the borehole wall to improve its stability; at the same time, it can ensure the air permeability of the borehole wall after the reinforcement, which is convenient for subsequent gas extraction. |
