Abstract

本实用新型公开了一种LWD-350专用无磁钻铤，由一整根钻铤加工而成，其内孔根据LWD-350仪器外径及长度要求加工成了相应尺寸的阶梯孔，且各内孔同轴度，其内部装配定位键。本实用新型将现有技术中的两个短节合二为一，由一整根钻铤加工而成，极大地提高了钻铤的使用安全性，设计科学合理，节能环保，适于油田推广使用。

Description

LWD-350专用无磁钻铤
技术领域
本实用新型涉及一种无磁钻铤，特别是LWD-350专用无磁钻铤。
背景技术
由于加工难度较大，现有无磁钻铤将LWD-350的流管部分装在一个悬挂短节中，而探管部分则装在另一个短节里面，这两个短节拧在一起组成一个钻铤，由于两个短节通过螺纹连结拧在一起，存在一个安全隐患。
实用新型内容
为克服上述现有技术缺陷，本实用新型公开了一种LWD-350专用无磁钻铤，把现有技术中的两个短节做成了一个整体，消除了安全隐患，增强了无磁钻铤使用的安全性。
本实用新型所采用的技术方案是一种LWD-350专用无磁钻铤，由一整根钻铤加工而成，其内孔根据LWD-350仪器外径及长度要求加工成了相应尺寸的阶梯孔，且各内孔同轴度，其内部装配定位键。
本实用新型的有益效果是本实用新型将现有技术中的两个短节合二为一，由一整根钻铤加工而成，不存在现有技术的两个短节问题，极大地提高了钻铤的使用安全性，设计科学合理，节能环保，适于油田推广使用。
附图说明
下面结合附图对本实用新型作进一步说明
