Cement/Formation Interface System and its Effect on the Petroleum Engineering

The cementation quality of cement/formation interface system (CFIS) is one of the most urgent problem, which need to be resolved in petroleum engineering. The structure and compositions of the CFIS are analyzed, and the status change model and dynamic damage model of the CFIS are established. At two aspects of the oil field exploitation and fluid migration, the effects of the isolation invalidity of the CFIS are studied, and the importance of the solution to the problems is discussed. The study revealed that must be set about at systematic angles, and the bond problems of the CFIS can be to resolved fundamentality. Otherwise, the complex issue is insistent with the cementing field for a long period.
