Fluid invasion-induced geological risks during drilling in marine natural gas hydrate reservoirs:A mini reviewOA
Geological risks are the main obstacles encountered during drilling in marine natural gas hydrate reservoirs.This review aims to provide a primary insight into the geological risks in the process of drilling in marine hydrate reservoirs.Different geological risks and their characteristics will be analyzed,together with a discussion of possible influencing factors.Geological risks occurring in the marine natural gas drilling process have a close association with uncontrollable drilling fluid invasion and hydrate dissociation.Finally,the mechanisms of drilling risks and control strategies for safe drilling are highlighted.Results can give a reference to drilling risk prediction and control for drilling in marine natural gas hydrate reservoirs efficiently.
