摘要: 在石油钻井过程中牙轮钻头破岩时牙齿的受力是相当复杂的,钻头的使用寿命与牙齿的受力大小直接相关,为了探索钻头牙齿在破岩过程中的受力规律,在实验室条件下对牙轮钻头牙齿进行了测力试验研究,但获得的试验数据中却存在大量噪声,严重影响了对试验数据的处理和分析,采用小波变换对试验数据进行了去噪处理,获得了很好的结果,有效解决了试验数据中存在大量噪声的难题。

Abstract:

When petroleum well drilling process roller bit broken crag the tooth stress is quite complex. The drill bit service life and tooth stress size has direct correlation. In order to explore the drill bit tooth in broken crag process stress rule, the strength experimental study of the roller bit tooth was made under the laboratory condition. The roller bit tooth had measured the strength experimental study, but the results of the tentative data had the massive noises actually, affected seriously to tentative data processing and the analysis, with the wavelet transform pair tentative data carrying on the chirp processing, obtained the very good result. The massive noises the difficult problem was solved effectively.

Key words: roller bit, measurement force of tooth, de noising analysis, wavelet transfer
