CEMENT COMPOSITIONS FOR CEMENTING WELLS, ALLOWING PRESSURE GAS-CHANNELING IN THE CEMENTED ANNULUS TO BE CONTROLLED |
| 摘要 |
<p>36 The invention relates to cement compositions for cementing wells, which allow pressure gas-channeling to he effectively controlled up to more than about 485.degree.F. The cement composition contains a styrenebutadiene latex and a stabilizer. The film of latex interrupts gas-channeling after an extremely brief path.</p> |
