WELL CEMENT COMPOSITION INCLUDING MULTI-COMPONENT FIBERS AND METHOD OF CEMENTING USING THE SAME |
| 摘要 |
A well cement composition includes a hydraulic well cement and multi-component fibers having at least a first polymeric composition and a second polymeric composition. At least a portion of the external surfaces of the multi-component fibers includes the first polymeric composition, and the first polymeric composition includes an ethylene-methacrylic acid or ethylene-acrylic acid copolymer. A method of cementing a subterranean well is also described. The method includes introducing the well cement composition into a wellbore, wherein the well cement composition further comprises water, and forming a cured cement in the wellbore. |
