CEMENTING COMPOSITIONS AND USE OF SUCH COMPOSITIONS FOR CEMENTING OIL WELLS OR THE LIKE

摘要

The present invention provides cementing compositions for oil wells or the like and including reinforcing fibers of amorphous cast metal. Compositions of the invention have mechanical properties that are improved, particularly from the point of view of tensile strength, and they are particularly suitable for cementing zones that are subjected to extreme dynamic stresses, such as perforation zones and branch well junctions.
