Abstract:
An example wellbore cementing system includes a casing to line at least part of a wellbore, and a pipe to introduce cement slurry containing capsules into the wellbore. The capsules include an accelerator. The accelerator reacts with the cement slurry to affect a thickening time of the cement slurry. The example system also includes a substructure having shearing pins. The substructure is arranged to receive the cement slurry from the pipe. The substructure is configured rotate to break at least some of the capsules in the cement slurry.

Claim (Index 12):
A method comprising:\n forcing cement slurry containing capsules into the at least part of a wellbore via through a shearing structure located in the wellbore at a terminal end of a pipe, the shearing substructure having an output to the wellbore, the capsules comprising an accelerator, the accelerator to react with the cement slurry to affect a thickening time of the cement slurry; breaking at least some of the capsules using the shearing substructure, the shearing substructure comprising shearing pins located at the output of the shearing substructure, the shearing substructure being configured to rotate to cause the shearing pins to rotate while the cement slurry passes through the shearing pins causing the at least some capsules passing through the shearing substructure to break; breaking at least some of the capsules using a turbulent flow produced within the cement slurry in the wellbore; and melting at least some of the capsules within the cement slurry in the wellbore.
