摘要: 为了进一步提高钻井井控标准的科学性和可操作性，充分发挥其在钻井作业中的指导作用，对现行8项有关钻井井控标准（国家标准和行业标准）进行了简要介绍，分析了其特点；立足于当前钻井井控技术现状，按照钻井作业对井控技术与装置的需求，充分考虑井控装置的功能、井控装置最低配备要求并基于保证必要安全备用余量的思路，指出当前6项有效标准中存在防喷器组合形式、井控管汇流程、关井程序不合理等17项主要问题。通过对问题的深入分析，提出了可行的解决方案（修订建议）并进行了解释。研究与解决方案都基于油田钻井井控实际，可为下一步完善与修订相关井控标准提供依据。Abstract: In order to improve the scientificity and practicability of well control standards and give full play to the guiding role of well control standards in drilling operation,this paper analyzed 8 current drilling well control standards(national standards and industry standards).Based on the current status of well control technology,and the requirements on well control techniques and devices in drilling,giving full consideration of well control function of the devices and well control equipment with minimum requirements and the necessary safety margin,the paper pointed out 17 major problems in the current 6 effective standards,in terms of BOP combinations,well control manifold and shut in procedures.Through in-depth analysis of the problems,possible solutions were proposed and explained.Proposed changes were based on the actual oilfield well control situation,which provided basis for further improvement and revision of relevant well control standards.
