去年，IADC 欠平衡作业和管理压力钻井 (UBO &MPD) 委员会发布了《立管气体处理指南》，以解决深水钻井过程中利用地面背压 MPD 或安装的立管气体处理系统时与立管中的气体相关的挑战。在里约热内卢举行的 2024 年 IADC/SPE MPD & UBO 会议上，IADC 立管气体小组委员会成员提交了一系列论文，讨论了指南背后的基本概念以及指南在现场的实际应用。9月 18 日，Equinor 钻井和油井高级工程师、小组委员会成员 Mario Teixeira 在会议上向DC介绍了这些概念。他指出，其中一些概念在行业中鲜为人知或在现场操作中应用不一致。特别是，他讨论了未解决的立管气体事件可能导致的不受控制的立管卸载，以及为什么行业更好地了解所涉及的风险很重要。

Last year, the IADC Underbalanced Operations and Managed Pressure Drilling (UBO &MPD) Committee published the Riser Gas Handling Guidelines to address challenges associated with gas in the riser during deepwater drilling while utilizing surface back pressure MPD or installed riser gas handling systems. During the 2024 IADC/SPE MPD & UBO Conference in Rio de Janeiro, members of IADC’s Gas in the Riser Subcommittee presented a series of papers discussing the underlying concepts behind the guidelines and the practical applications of the guidelines in the field. Speaking to DC from the conference on 18 September, Mario Teixeira, Senior Engineer – Drilling and Wells at Equinor and a member of the subcommittee, spoke about these concepts. Some of these, he noted, are little known in industry or inconsistently applied in field operations. In particular, he discussed the uncontrolled riser unloading that can result from unaddressed gas-in-riser events and why it is important for industry to better understand the risks involved.
