| 中文摘要:古龙1井是大庆油田2008年完钻最深的一口天然气探井，在三开Ф311.2 mm井眼进行了空气/雾化钻井实践。针对实际钻进中存在的问题，对比分析了几种不同介质气体钻井方式在松辽盆地泉二段以下的应用情况，并优选了合适的钻进方式。实钻结果表明，该井创造了大庆油田松辽盆地有史以来Ф311.2 mm井段空气钻进至井深4301.05 m，井段最深、温度最高的记录，在井壁失稳、持续出水的情况下，克服重重困难，空气、雾化钻进了1196.05 m，平均机械钻速7.9 m/h，单只钻头最高进尺达到了552.86 m。

| Abstract:Well Gulong1 is the deepest natural gas exploration well of Daqing oil field in 2008, air/mist drilling practice was made in the Ф311.2 mm third spud section. According to the existing problems, analysis on the application was made for air drilling with different mediums and proper drilling method was optimally selected. The practice showed that the record was made with the deepest well depth and the highest temperature for air drilling in Ф311.2 mm well section in Daqing oil field Song-Liao basin, the air/mist drilling reached to 1196.05 m with average penetration rate of 7.9 m/h, and the maximum drilling footage was up to 552.86 m. |
