钻具稳定器断裂失效分析及改进措施

Failure analysis for Stabilizers.

针对钻具稳定器使用寿命低、断裂失效频繁的问题,对典型失效样品早期失效原因进行了较为系统的分析研究,根据试验分析结果提出了在选材和热处理、结构设计和制造,以及标准化和质量控制等方面应当采取的改进措施。

In the light of the poor service life and frequent failure of the stabilizers, this article makes a systematic study on the typical premature failure causes, and on the basis of test results, presents Criteria concerning material selection and heat treatment, structural design and manufacture.
