毫米波钻井技术

Millimeter Wave Drilling Technology

  • 摘要: 为了给我国毫米波钻井技术的研发提供借鉴和思路,研究了国外毫米波钻井技术的现状和成果。毫米波钻井技术是利用大功率回旋管毫米波发射机发射的毫米波电磁能强束熔化蒸发岩石,高压空气或氮气携岩屑(实际是携纳米级粉末)进行钻井。毫米波技术可省去常规钻井更换钻头和下套管固井等工序,因此可以缩短钻井周期。室内试验表明,毫米波钻井的机械钻速与毫米波的功率、岩石的蒸发比能及吸收功率密度密切相关。毫米波钻井技术为提高钻井速度、降低钻井成本提供了一种可行的新思路和新方法。

     

    Abstract: This paper introduces the millimeter wave drilling technique abroad,which uses the high-power gyrotron transmitter to emit intensive beam of millimeter-wave electromagnetic energy for melting or vaporizing rocks,and uses high pressure air or nitrogen for carrying cuttings(micron-sized powder actually),including the principle of drilling,theoretical research status and achievements and conclusion obtained by laboratory experiment.It can shorten the drilling time by eliminating the process of changing bit and running casing and cementing as conventional drilling method.The laboratory experiment shows that ROP of millimeter wave drilling is related to the millimeter wave power,specific energy for rock vaporization and absorption power density.Millimeter wave drilling technology will be a novel idea and method for improving drilling rate and reducing cost.
