Overview of Deepwater Drilling Engineering Risk

Deepwater drilling is an essential part of deepwater oil and gas exploration and development. Because of the complex-ity of deepwater operating environment, there are many risks in deepwater drilling engineering, such as shallow water flow, shallow gas, natural gas hydrate, internal sea wave, giant wind, low temperature and so on. These risks can be divided into four categories? shallow geological hazards, marine environment hazards, marine meteorological disasters and deepwater operations particularity. Through discussion on the causes of various hazards and action modes, the influence of the various hazards on deepwater drilling has been understood and evaluated comprehensively and systematically, and appropriate methods can be taken properly to prevent and reduce the deepwater drilling engineering risks.
