摘要：An apparatus for determining shear bond strength of a cement to be set within

a wellbore penetrating a subterranean formation consists of a housing, a vertical rodwhich extends from the uppermost portion of the housing through the lowermostportion of the housing, a base plate for positioning onto the bottom of the housing andfor supporting the lowermost portion of the vertical rod, and a test plate for positioningonto the top of the housing through which the uppermost portion of the vertical rodextends. The apparatus may further contain a push rod. Shear bond strength isdetermined by introducing into the housing a sample core of the formation prior tointroduction of a slurry containing the cement. The force required to break the bondbetween the vertical rod and the set cement may be used to determine the shearstrength between the casing within the wellbore and the set cement when the cement ishardened within the wellbore. The force required to break the bond between the setcement and the sample core may be used to determine the shear strength between theset cement and formation core when the cement is hardened within the wellbore.
