中文摘要:
      随着渤海部分老油田开发进入中后期,未来越来越多海上油气井将被弃置,但受海水阻隔及受安全环保要求限制,海洋油田弃井面临很多亟待解决的技术难题,理论和技术还需丰富。通过对相关文献和作业数据的调研分析,总结了渤海油气井弃置的作业历程和技术现状,从海洋安全环保、提高渤海弃井作业效率、油田全生命周期完整性等角度分析了弃井技术对渤海油田开发的重要性,对井下管柱打捞技术、环空带压治理技术、隔水套管泥面以下切割及处理技术等在渤海已有成熟应用的工艺和技术进行了介绍,并从目前制约海洋弃井的单筒双井弃井、多分支井弃井等制约作业工期的瓶颈问题,分析了渤海弃井所面临的挑战,并对未来油气井弃置技术进行了展望。渤海油田通过多年的弃井作业经验积累已形成特有的弃井作业体系,但未来仍然需要加强弃井技术研究,保证渤海油田开发全生命周期的安全。
英文摘要:
      As some old oilfields in the Bohai Sea enter the middle and late stages, more and more offshore oil and gas wells will be abandoned in the future. However, due to seawater barriers and restrictions on safety and environmental protection, offshore oilfield abandoned wells face many technical problems, theory and technology. Still need to be rich. Through the investigation and analysis of relevant literature and operation data, the operation history and technical status of the abandonment of oil and gas wells in Bohai Sea are reviewed. The abandonment technology is analyzed from the perspectives of marine safety and environmental protection, improving the efficiency of the abandonment of the Bohai Sea, and the integrity of the life cycle of the oilfield. The importance of the development of Bohai Oilfield has been carried out on the techniques and technologies that have been applied in Bohai Sea for the technology of drilling downhole string salvage, the treatment of annulus and pressure, the cutting and treatment technology of the water-proof casing below the mud surface, and the abandoned engineering equipment. This paper introduces the bottlenecks that restrict the operation period from the single-tube double-well abandoned wells and multi-branch abandoned wells that restrict the marine abandonment wells, analyzes the challenges faced by the Bohai abandoned wells, and forecasts the future oil and gas well disposal technology. . Bohai Oilfield has formed a unique abandonment operation system through years of experience in abandoning well operations. However, in the future, it is still necessary to strengthen the research on abandoned well technology to ensure the safety of the whole life cycle of Bohai Oilfield Development.
