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。

Based on the basic theroy of fluid dynamics, this paper establishes a model of flow mechanics for turbulent flow, then uses this model to carry on a numerical simulation study on the conventional auger drill stabilizer annular flow field.

基于流体力学基本理论，本文建立了一套钻柱稳定器湍流模式力学模型，并采用该模型，对气体钻井常规螺旋钻柱稳定器环空流场进行了数值模拟研究。

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。

The result of the caculation shows that the conventional auger drill stabilizer annular flow field has a weak ability in cutting-carrying and lifting; debris may deposite at the head, root of helical blade and the bottom side of the spiral channel.

计算表明：常规螺旋钻柱稳定器环空气体携岩举升能力弱，螺旋叶片头部、根部、螺旋流道下部下侧面容易出现岩屑滞留和沉积。

Through the analysis of the formation principle of helical curves , the uniform equation of taper surface helical curves is established and the optimization analysis is made of the screw wing cutting edge of the taper spiral auger s tip .

通过分析螺旋线的形成原理，建立了锥形面螺旋线的统一方程，并对圆锥螺旋钻尖的翼片刀刃部分进行了优化分析。

The physiology of the skin machine body for the sake of the environment in the maintenance stability, but eject a body metabolism creation of metabolism thing BE'grease', summer perspire many various skin disease light or good, autumn perspire little metabolism thing metabolism don't go out, various skin disease made, this be the skin machine body of various burning disease.

皮肤机体的生理为了维持内环境稳定，而排出身体代谢产生的代谢物是'油泥'，夏天出汗多各种皮肤病就轻或好了，秋天出汗少代谢物代谢不出去，各种皮肤病就犯了，这就是皮肤机体的各种炎症。

If I had anything tender in me, I shot it dead.

如果我有什么招标的话，我枪死亡。
