[求助]
小弟初次寫SCI，求助翻譯題目和摘要，不甚感激
|
|
題目：深井/超深井雙作用強側切開窗鉆頭設計加工技術研究 摘要：針對深井/超深井套管開窗側鉆中套管壁厚且強度高、巖石可鉆性差、鉆頭切削齒極易先期鈍化導致的開窗效率低/開窗失敗的問題，創(chuàng)新性研究設計出一種雙作用強側切開窗鉆頭。設計中考慮了開窗鉆頭鉆進的穩(wěn)定性及載荷分布的均勻性，鉆頭冠部設計為內錐-雙圓弧面，采用“等切削、等功率與等磨損”布齒理念和“螺旋高低交錯”布齒規(guī)律，滿足既能高效側切金屬又能快速切削巖石的設計目標；通過專有加工工藝技術的研究，完成了該新型鉆頭的加工試制。現(xiàn)場實際應用結果表明，研制的雙作用強側切開窗鉆頭能很好的適應深井/超深井硬地層的開窗側鉆作業(yè)。 |

Title: Analysis on the design and processing technique of dual-use & strong side-cutting fenestration drill for drilling deep well and super deep well Abstract: In the window sidetracking drilling for deep well and super deep well, the low efficiency and possible failure in window drilling are mainly due to the high thickness and strength of casing wall, poor drillability of rock and the high possibility of initial passivation of drill cutting teeth. As a result, in this paper a dual-use and strong side cutting fenestration drill was designed by innovative research. To design such a drill, the stability of drill and the homogeneity of load distribution were considered, and the head of drill was designed to be an inner cone - double circular arc surface. The drill teeth were designed according to the concept of “uniform cutting, uniform power, and uniform abrasion” , and were distributed in the spiral and staggered pattern, which can meet the purpose of both efficient metal side-cutting and rock cutting; Through analyzing the specialized processing technique, the processing test of this new-type drill was conducted. The on-site practical application results showed that the designed fenestration drill with characteristics of dual-use and strong side cutting possesses the adaptability in window sidetracking drilling the hard formation of deep well and super deep well. 希望多多交流www.once-translation.com |
