摘要
塔河油田TK480井完钻井深5593.10m,裸眼井段长达4246m。文章介绍了该井钻探过程中的经验和复杂事故的处理情况,认识和总结了在粘土含量较高的白垩系、侏罗系和石炭系及砂泥岩频繁互层、垮塌严重地层中裸眼钻井的钻井液技术。
The hole depth is 5,593.10 m and open interval is 4,246 m long after well completion in TK 480 well.The paper introduces the experience and handling down-hole trouble in the drilling.It also summarizes drilling fluid of open hole drilling encountered the Cretaceous,Jurassic and Carboniferous with rich clay,along with sand-mud interbedded formation frequently and seriously collapsed formation.
