钻柱稳定器结构特点分析

CONFIGURATIONS OF DRILLING STRING STABILIZER

稳定器是井斜控制井底钻具组合中的重要组件。在钻井中 ,目前广泛使用的仍然是常规的、不可变径稳定器。在查阅这类资料时 ,全面反映我国稳定器设计的相关资料太少。而美国稳定器却有多姿的结构、丰富的资料 ,特别在稳定器的整体结构和扶正段结构上很有借鉴的价值。通过对稳定器的资料综合与整理 ,较为全面地介绍稳定器结构类型和扶正段结构特点 ,为国内同仁对稳定器的设计、制造和使用提供参考 。

Stabilizer is an important component in BHA of hole deviation control. Up to now, the conventional and nonadjustable stabilizers have been still used widely in the many drilling operations .The information of this type stabilizer is too little to reflex design of all the stabilizers. However, the American stabilizer has the varied style and the plentiful information, especially, there is much reference worth in their integration construction and thee style of stabilized section .Through the information of drilling string stabilizer from USA has been sorted and synthesized, their design types and configurations of stabilized section were described in the paper in details. It provided references for the stabilizer design, manufacturing and application.
