摘要： 低渗透、特低渗透乃至超低渗透油藏的开发利用是中国石油不得不长期面对的一个问题。随着长庆油田大面积成功开发利用超低渗油藏工作的深入开展,钻井领域逐步形成了积极的井控措施。纵观长庆油田42年开发历史,钻井井控经历了粗放式管理、探索式重新认识、积极井控技术发展进步3个阶段,指出了积极井控的技术要点,强调越是低压、低渗、低孔油藏,越要采取积极的井控措施。

Abstract: Development and utilization of low-permeability and ultra-low permeability oil reservoirs is an issue PetroChina has to face on a long-term basis. Successful development and utilization of ultra-low permeability reservoirs in large areas in Changqing Oilfield allows active well control measures to be gradually established in the drilling sector. So far as the development history of 42 years in Changqing, well control for drilling operation has experienced three technological development stages——extensive management, re-understanding and active well control. This article focuses on the key technological points of well control and stresses that it is necessary to take active well control measures for low-pressure, low permeability and low-porosity reservoirs.

Key words: ultra-low permeability, active well control, technology
