【摘要】：北极冷海地区油气资源丰富,是目前国际石油公司关注的热点,了解极地冷海钻井技术挑战和关键技术现状,对推进极地冷海钻井技术进步、实现极地冷海油气资源的高效开发具有重要意义。为此,通过大量文献调研和实地考察,分析了国内外极地冷海钻井装备及关键技术的现状和主要研究进展,得到了以下认识:恶劣的作业环境、长距离的后勤保障和苛刻的环保要求,是极地冷海油气勘探开发面临的首要难题;坐底式平台、人工岛、抗冰自升式平台和浮式平台等是目前极地冷海钻井作业采用的关键装备,低温钻机、全封闭抗冰平台及耐低温新型材料等是极地冷海钻井亟待突破的关键装备及材料。调研分析认为:冻土层钻井技术、低温钻井液和固井技术、万米大位移井钻井技术、极地灾害风险评价及控制技术和钻井废弃物环保排放技术是未来极地冷海钻井技术的主要攻关方向,是实现极地冷海油气资源高效开发的关键。
[Abstract]:The Arctic Cold Sea region is rich in oil and gas resources, which is the focus of international oil companies' attention at present. Understanding the technical challenges and key technology status of polar cold sea drilling will promote the progress of polar cold sea drilling technology.It is of great significance to realize the efficient exploitation of polar cold sea oil and gas resources.Therefore, through a lot of literature investigation and field investigation, this paper analyzes the present situation and main research progress of polar cold sea drilling equipment and key technologies at home and abroad, and obtains the following understanding: poor working environment,Long distance logistic support and harsh environmental protection requirements are the most important problems facing the exploration and development of oil and gas in the polar cold sea.Anti-ice jack-up platform and floating platform are the key equipment used in polar cold sea drilling at present. Low temperature drilling rig, fully closed anti-ice platform and new materials of low temperature resistance are the key equipment and materials for polar cold sea drilling to be urgently needed to break through.Through investigation and analysis, it is concluded that: permafrost drilling technology, low temperature drilling fluid and cementing technology, ten thousand meters long reach well drilling technology,Polar disaster risk assessment and control technology and drilling waste environmental protection discharge technology are the main research direction of polar cold sea drilling technology in the future and the key to realize the efficient exploitation of polar cold sea oil and gas resources.
