Methods and Cement Compositions Utilizing Treated Polyolefin Fibers |
| 摘要 |
Methods and cement compositions are provided that utilize treated polyolefin fibers for lost circulation and/or mechanical property enhancement. Disclosed is a method comprising: providing a cement composition comprising: a hydraulic cement; water; and treated polyolefin fibers that are rod-shaped and have a length in a range from about 0.0625 inches to about 0.25 inches, wherein the treated polyolefin fibers have been treated with a surfactant to make the treated polyolefin fibers hydrophilic; placing the cement composition in a selected location; and allowing the cement composition to set. |

1. A method of cementing in a well bore comprising:
providing a non-foamed cement composition comprising:
a hydraulic cement;water; andtreated polyolefin fibers that are non-fibrillated, rod-shaped and have a length in a range from about 0.0625 inches to about 0.1825 inches, wherein the treated polyolefin fibers have been treated with a surfactant to make the treated polyolefin fibers hydrophilic; placing the cement composition in a well bore, wherein the treated polyolefin fibers reduce loss of fluid circulation of the non-foamed cement composition and/or any subsequently introduced fluids; and allowing the cement composition to set in the well bore. |
