查询词典 auger drilling

The research shows that there is not any published article introduce stablizer that used in gas drilling, thus there is no evaluation about the conventional auger drill stabilizer's impact on cutting-carrying and lifting ability of the annulus gas.

调研发现，公开发表的文献中，目前没有文章介绍专用于气体钻井的钻柱稳定器，也没有就气体钻井使用常规螺旋钻柱稳定器对环空气体携岩举升能力造成的影响进行评价。

With the help of modern computational fluid dynamics tecnology, this thesis carries on a numerical simulation of annulus multiphase flow of the conventional auger drill stabilizer; it points out the deficiency of the annulus gas in cutting-carrying and lifting; and attempts to develop a drill stabilizer that are suitable for the gas drilling.

本文试图借助现代计算流体力学技术，对常规螺旋钻柱稳定器环空多相流动规律进行数值模拟研究，指出在环空气体携岩举升方面存在的不足，开发一套适合于气体钻井的新型钻柱稳定器，提出全井段环空流场改善方法，实现气体钻井防斜打快，减少冲蚀，提高井眼净化能力的目的。
