USE OF METHYLHYDROXYETHYL CELLULOSE AS CEMENT ADDITIVE |
摘要 |
Methylhydroxyethyl cellulose may be used as an additive in cement slurries in the treatment of wells to prevent or reduce the occurrence of gas channeling. In addition to acting as a gas control additive, methylhydroxyethyl cellulose controls fluid loss, minimizes free fluid and stabilizes foam during cementing of the well. |
