【摘要】 深水钻井是深水油气勘探开发必不可少的环节。由于作业环境的复杂性,深水钻井工程面临诸多风险,如浅水流、浅层气、天然气水合物、海洋内波、强风和低温等。这些风险可归纳为四类:浅层地质灾害、海洋环境危害、海洋气象灾害及深水操作特殊性。通过对各种风险产生原因和作用方式的论述,全面系统地认识和评价了各种风险对深水钻井的影响,以便采取恰当的方法预防和降低深水钻井的工程风险。更多还原

【Abstract】 Deepwater drilling is an essential part of deepwater oil and gas exploration and development.Because of the complexity 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 categoriesshallow 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.更多还原
