摘要
塔河油田 S88井三开 311.1mm裸眼井段长达 32 6 2 m,钻进中存在严重的井眼失稳问题。在分析井眼失稳机理的基础上 ,给出了相应的技术措施 ,现场应用表明 ,该技术措施很好地解决了该井技术难题 ,满足了井下安全钻进的需要 。
Borehole walls sloughing happened when drilling 311.1mm long open hole(3262m) in S88 well in Tahe Oilfield. Based on analyzing mechanics of hole collapse, the effective technology is taken. Field application shows that the technology solved difficulties successfully, fulfilled safe downhole drilling. The technology provides strong safeguard for rapid penetration in Tahe.
