关于两个井控争议问题的讨论

Discussion of Two Controversial Issues on Well Control

防喷器操作手柄位置和井口防喷器的组合形式在石油行业标准中没有明确规定,而防喷器操作手柄位置和井口防喷器的组合形式涉及到井控设计和现场防喷器的使用,对井控具有重要影响。为此,针对目前井控现状,分析了防喷器控制原理并查阅了文献资料,指出了因操作手柄位置不合理带来的井控隐患,建议钻井中防喷器操作手柄的最佳位置为"中"位;分析了防喷器组合的功能并查阅了井控标准,指出了防喷器组合形式和安装顺序等方面存在的问题,针对不同压力级别,提出了防喷器的组合方式及安装顺序的建议。对于防喷器操作手柄位置和井口防喷器的组合形式,需要修订现行标准以进行规范,并对标准修订的重点内容提出了建议。

BOP handle position and the BOP configuration have not yet been clearly defined in petroleum industry,while all these involve the BOP design and field application which impacts the well control significantly.The BOP control mechanism was analyzed according to current well control status based on reviewed references.This paper pointed out some potential problems for well control caused by improper BOP handle positions,and suggested that the best handle position in drilling is middle.The different functions of BOP configuration were analyzed,and the problems existing in BOP configuration and installation order were pointed out.The BOP configuration and installation order was provided for different pressure levels.It is necessary to revise the existing standards related to the BOP handle position and BOP configuration and recommendations were provided.
