为了正确地计算与掌握轴心压力,提高鑽進效率,我們在原「地质工作通报」第18期的工作研究欄中,曾发表了華北地質分局刘九如同志的「推行科学計算軸心压力的一些體会」一文,並希望讀者們根据实际工作經驗,進一步探討有关計算与掌握轴心压力的方法和問題。现在我們收到了一些讀者的看法和意见,茲先發表兩篇,欢迎大家进一步發表意見,应该指出,这两篇文章並不代表編委会的意见,也不表示我們同意这种看法,只供进一步研究此一问题之参考。
In order to correctly calculate and grasp the pressure on the core and improve the drilling efficiency, we published in the Work Research Column No. 18 of the original Geological Work Bulletin on the work of some of the authors of Comrade Liu Jiu-ru of North China Bureau of Geology, Will be "a text, and hope that readers based on actual work experience, to further explore ways to calculate and grasp the pressure on the axis and problems. Now that we have received some opinions and opinions of readers, we first publish two articles. We welcome further public comment. It should be pointed out that these two articles do not represent the views of the Editorial Board or that we agree with this view only for Further study of this issue for reference.
