俄罗斯超深井钻井进展及技术进步

Drilling progress and technological improvement of ultradeep wells in Russia

俄罗斯油气资源丰富,超深井钻井起步较早。调研了前苏联时期重点超深井钻井概况,分析了科拉超深井钻井目的、钻井过程、技术成果;追踪了萨哈林-1项目进展情况,阐述了油田分布、开发进展、超深井钻井现状、钻井新技术应用等。分析认为,俄罗斯超深井钻井技术进步对我国钻井工艺有很好的借鉴作用,俄罗斯钻井技术存在一定短板,为我国钻井技术进入俄罗斯市场提供了契机。建议我国加强俄罗斯超深井钻井技术引进、为俄罗斯提供石油工程技术服务、参与俄罗斯油田开发,促进我国超深井钻井技术发展。

In Russia,there are abundant oil and gas resources and the drilling of ultradeep wells starts earlier.In this paper,the drilling summary of key ultradeep wells in the period of former Soviet Union was investigated,and the drilling target,drilling process and technological achievement of Kola ultradeep well were analyzed.Then,the progress of Sakhalin-1 project was tracked,and oilfield distribution,development progress,drilling status of ultradeep wells and application of new drilling technologies were described.It is indicated that the progress of Russia’s ultradeep well drilling technologies provides valuable reference for our drilling technologies,while Russia’s drilling technologies have some weaknesses,which provides the opportunity for our drilling technologies to enter Russian market.We shall strengthen introducing the Russia’s ultradeep well drilling technologies,provide Russia with petroleum engineering technology service and participate in Russia’s oilfield development,so as to promote the development of our ultradeep well drilling technologies.
