Abstract:

The article suggests a method for determining the volume shrinkage of cement slurry. It involves measuring velocity of fluid or gas filtration through a gap between the cement stone and the wall of the device cell formed as a result of volume shrinkage. A standard and widespread cell is used for water loss measurement according to API RP 10B-2. The experiments were carried out with the standard cementing slurries. The shrinkage of heavy cement slurry with the density of 1900 kg/m³ and the shrinkage of light cement slurry with the density of 1600 kg/m³ were determined. The flowrates of nitrogen and kerosene were measured. It is shown that for light cement slurries the suggested method shows good agreement between the experiments and can be applied in practice. For heavy cement slurries the suggested method gives only qualitative results.
