摘要:

在油气开采过程中,连续管作业因具有作业速度快、对地层伤害小、劳动强度低等优势而备受行业关注,连续管作业的研究是一个系统工程,涉及多个方面。从国内外文献发表的情况以及主要研究学者开始论述,回顾了连续管作业的发展过程,并对目前国内现有的相关成果进行了归纳总结。目前,连续管作业正处于快速发展阶段,但针对连续管在超深井应用进行的研究很有限。阐述了在超深井连续管下入性、连续管水平段延伸、连续管作业施工参数优化、连续管作业井下安全评估等方面开展的相关研究。根据超深井连续管作业研究现状,建议开展基于数智技术的连续管疲劳寿命实时预警技术、牵引器带动连续管延伸能力、耐高温工具和液体研发等方面的研究,解决连续管在超深井作业的技术难题。

Abstract:

In oil and gas extraction, coiled tubing technology has attracted much attention because of its advantages such as fast operation time, little damage to the formation low labor intensity, etc. The research of coiled tubing technology is a systematic project involving many aspects. This paper first starts the discussion from the domestic and international literature published and the main research scholars review the development process of coiled tubing technology, and summarise the relevant achievements existing in China. At present, the coiled tubing technology is in the stage of rapid development, but the research of coiled tubing in ultra-deep wells is minimal. The authors describe the relevant research carried out by the team on the downhole accessibility of coiled tubing in ultra-deep wells, the extension of the horizontal section of coiled tubing, the optimization of the construction parameters of coiled tubing operation, and the downhole safety assessment of coiled tubing operation. According to the current status of coiled tubing technology research in ultra-deep wells, it is suggested to carry out the research related to the real-time warning technology of coiled tubing fatigue life based on the digital intelligence technology, the ability of tractor?driven coiled tubing extension, and the research and development of high?temperature?resistant tools and fluids, to solve the technical difficulties of coiled tubing operation in ultra-deep wells.

Key words: Coiled tubing operation technology, Ultra-deep wells, Digital intelligence technology, Tractor?driven, High temperature and pressure
