Research on reamer s applicability in directional kick off intervals;
扩眼器在定向造斜段的应用可行性研究
This made the requirement of the down-casing reamer increasing,which is more durable and more reliable.
管下扩眼是一项不常用的技术 ,但随着石油工业的发展 ,钻井难度越来越大 ,特别在深井和超深井中 ,常会遇到狗腿、键槽和缩径等复杂情况 ,而且在深井钻井中要求下多层管柱 ,这就增加了对更耐用更可靠的管下扩眼器的需求 ,而以往常用的可胀开牙轮扩眼器存在着某些内在问题 ,如牙轮寿命短、水力参数有限及部件薄弱 ,导致使用效果不理想。
