钻井井控安全的风险因素与技术对策
The Risk Factors and Technical Measures on the Drilling Well-Control

随着勘探开发由常规钻井向“三高两浅”井、页岩油–页岩气的大位移水平井和山前构造深井、超深井等高难度钻井领域转移，钻井井控的风险等级、管控难度和技术要求也随之大幅度提高。为进一步突出钻井安全生产中的井控安全这个核心，本文系统分析了钻井井控安全的发展现状、风险因素及其技术对策，是钻井井控实施精细管理、升级管理、创新管理、科学管理，进而迈向文化管理的战略思考和积极实践。
As the exploration and development transfer from conventional drilling to the difficult drilling fields of “three-high and two-shallow” wells, the large displacement horizontal well for the shale-oil/shale-gas, and the deep-wells, ultra-deep wells in the foreland structures, the risk levels, control difficulties and technical requirements of drilling well-control are increased significantly. To pay special attention to the key works of drilling well-control safety in the safe production, in this paper, the systematic analysis of the present situations, risk factors and technical measures on the drilling well-control safety are the strategic thinking and active practices for the upgrade management, innovation management, scientific management, culture management, etc.
