Key words:  deepwater cementing  cement slurry  cementing technology  research development

Abstract:

Deepwater cementing technique is one of the key techniques in deepwater oil and gas drilling and completion. In order to improve the research development of deepwater cementing, the problems confronted in deepwater cementing were comprehensively analyzed. Based on the summarization on foreign research development in cement slurry systems for deepwater cementing, cement displacement technology, cementing equipment, cementing technology and investigation on the longterm isolation capability of cement sheath，the following are conclusions: The deepwater cementing technique study should take the prerequisite for cement systems with simple design and convenient execution, the environment-friendly principle and the ultimate realization for long-term zonal isolation of cement sheath.
