摘要
旋转防喷器是实施欠平衡钻井、控压钻井的关键设备之一。由于其旋转总成装配方式,安装高度上的要求,以及内通径对钻具的要求,限制了涉及旋转防喷器的欠平衡、控压钻井技术的应用空间。为进一步拓宽旋转防喷器所涉及技术的应用空间,本文提出旋转防喷器组合式大通径(MCL)旋转总成的研究技术思路及技术指标,通过优化设计、强度校核、室内实验及现场试验,有效的验证其性能及技术指标完全能满足现场应用要求,便于现场拆卸与组装,提升了涉及旋转防喷器技术服务的应用空间,解决了当前困扰涉及旋转防喷器的技术应用的难题。
Rotary blowout preventer is one of the key equipment for implementing underbalanced drilling and controlled pres⁃sure drilling.Due to the the rotating assembly method,the requirements of the installation height,and the diameter require⁃ment for the drilling tool,the application space of the underbalanced and controlled pressure drilling technology involving the rotating blowout preventer is limited.In order to further broaden the application space of the technology involved in the rotary blowout preventer,a modular combined large diameter(MCL)rotary blowout preventer was developed.This paper analyzes the limitations of the current application of the rotary blowout preventer,and proposes the research technical ideas and technical indicators of the modular combined large diameter(MCL)rotary assembly of the rotary blowout preventer.Through optimized design,indoor experiments and field tests,The modular combined large-diameter(MCL)module rotating assembly of the rota⁃ry blowout preventer was verified,and its performance and technical indicators could fully meet the requirements of on-site application,facilitate on-site disassembly and assembly,and improve the application space involving the technical service of the rotary blowout preventer,so as to solve the current problems related to the technical application of the rotary blowout pre⁃venter.
