CEMENT GROUT FOR OIL WELLS OR SIMILAR LOW DENSITY AND LOW POROSITY |
| abstract |
The invention relates to grouts for cementing an oil well or the like with a density of between 0.9 g / cm3 and 1.3 g / cm3, consisting of a solid fraction and a liquid fraction, having a porosity (volume ratio of the liquid to solid fractions) of between 38% and 50%. Such cements have remarkable mechanical properties due to their very low porosity despite a very low density. |
