casing string
解釋
套管柱-
The second row s cell values are written in plain english, such as " number of cases. " fit attempts to concatenate a string like this through camel casing ; for example, " number of cases " becomes
如圖5所示，第二行單元格中的值是用普通的英文編寫的，例如「 number of cases 」 。 -
It can lead to not only quick wear and early failure of drill pipe but also the decrease of collapse resistance and burst resistance of casing string, which could cause casing collapse, casing deformation and casing leak, even well bore abandonment
其直接後果是：鉆柱快速磨損，導致過早失效；套管磨損會降低套管柱的抗擠強度和抗內壓強度，造成套管柱擠毀、變形及泄漏，嚴重時造成全井報廢。 -
Determines the default formats for dates, times, currency, numbers, sorting order of text, string comparisons, and casing for all computations on that thread
為該線程上的所有計算確定日期時間貨幣數字的默認格式，文本的排序順序，字元串的比較方式以及大小寫的轉換方式。 -
Converts the string from file system rules for casing to linguistic rules
將字元串從文件系統大小寫規則轉換為語義規則。 -
Based on the dynamics, a mechanical model calculating the drill string ' s eccentric wear is established, the approximation equation calculating the positive pressure on casing / drill string is derived out, and the major factors affecting the eccentric wear are analyzed
針對深井鉆井中的井口附件套管偏磨問題，以動力學為基礎，建立了鉆柱偏磨力學模型，推導出了套管鉆柱正壓力的近似計算公式，分析了影響偏磨的主要因素。 -
The bigger the effective eccentricity, the higher the upper drill string ' s lifting force, the higher the positive pressure on casing / drill string, and the more serious the wear
有效偏心距越大，上部提升力越大，套管鉆柱之間的正壓力將越大，磨損將越產重。 -
By using finite element method, full - scale tests and the strain survey method, as for the crescent - shaped wear casing, this paper has discussed on mechanism of casing collapse and its influence on casing collapse. furthermore, computing method for both uniform wear and crescent - shaped wear situation was introduced, which can be used directly for casing string design
採用有限元分析、實物試驗及實驗應變測量方法，研究了套管產生不均勻磨損時的擠毀失效機理及其對套管擠毀性能的影響，確定了均勻磨損和不均勻磨損對套管擠毀性能的計算方法，研究結果可直接用於套管柱強度設計和校核中。 -
Since the deeper the well, the higher the lifting force at the upper drill string, the deviation of derrick and the well head ' s eccentricity should be avoided by all means to prevent the severe eccentric wear on the casing which is caused by excessive effective eccentricity
由於上部鉆柱的提升力隨井深的增加而增加，因此應當盡量避免井口偏心或井架安裝不正，防止有效偏心距過大而造成近井口套管的嚴重偏磨。 -
