A new tool for the rheometric study of oil well cement slurries and other settling suspensions

摘要

An original rheometric geometry has been used in order to solve experimental problems related to the study of suspensions of coarse, heavy particles. This testing device has been used to characterize oil well cement slurries, which are settling suspensions of big industrial interest. The measurements show that the new geometry remedies efficiently for settlement and slip at the walls. Results are compared with those obtained using conventional geometries, and reveal the importance of the errors to which non-adapted instruments can lead.
