Research on reamer s applicability in directional kick off intervals;
擴眼器在定向造斜段的應用可行性研究
This made the requirement of the down-casing reamer increasing,which is more durable and more reliable.
管下擴眼是一項不常用的技術 ,但隨著石油工業的發展 ,鉆井難度越來越大 ,特別在深井和超深井中 ,常會遇到狗腿、鍵槽和縮徑等復雜情況 ,而且在深井鉆井中要求下多層管柱 ,這就增加了對更耐用更可靠的管下擴眼器的需求 ,而以往常用的可脹開牙輪擴眼器存在著某些內在問題 ,如牙輪壽命短、水力參數有限及部件薄弱 ,導致使用效果不理想。
