普光气田超深井钻井技术的进步与思考

Progress of Ultra-deep Well Drilling Technology in Puguang Gas Field and the Prospect

摘要:

普光气田是中国石化已成功开发的一个大型整装海相气田。对普光气田超深井钻井实践进行了全面的总结，将其划分为3个阶段：探索阶段、发展阶段和气体钻井阶段，机械钻速由探索阶段的0.99 m/h提高到发展阶段的1.70 m/h，再提高到气体钻井阶段的2.61 m/h，提速效果十分显著。并对加快中国石化超深井钻井技术的进步提出了一些建议。

Abstract:

Puguang gas field is a large-scale equipped marine gas field which has been successfully developed by SINOPEC. In this article, the drilling practices of ultra-deep wells in Puguang gas field were summarized comprehensively. The practices were divided into the exploratory stage, developing stage and gas drilling stage. From 0.99m/h in the exploratory stage, the ROP was raised to 1.70 and 2.61m/h in the developing stage and gas drilling stage respectively. The drilling speed-increasing effect is very obvious. Some proposals are put forward to speed up the progress of ultra-deep well drilling technology for Sinopec.
