摘要： Methods of designing a cementing operation for a cement body within a wellbore are described herein. One such method includes determining a stress for the cement body within the wellbore by simulating hydration of the cement body using cementing operation parameters and wellbore conditions. The hydration simulation includes calculating pore pressure for the cement body and accounting for changes in pore pressure associated with chemical shrinkage of the cement body. The method further includes designing a cementing operation using the stress for the cement body and the cementing operation parameters.
