摘要

Method of sealing of a tube or column of tubes expansu00ecvel in a hole of the shaft, and compressu00ecvel foam sealant, composition for sealing of a tube or column of tubes expansu00ecvel in a bore of the well. The present invention provides methods and compositions for sealing foam compressible to seal tube expandable in wells.The compressible sealing compositions for sealing pipe expanding are basically composed of hydraulic cement, a rubber latex, a latex rubber stabilizer.A gas and mixture of surfactants of foaming and foam stabilizers.
