| 摘 要： | 超短脉冲激光与岩石之间的相互作用是激光钻井破岩过程中的本质过程,该过程除了与岩石成分和岩石所处的外部环境有关外,还与激光入射条件有关。文中以红砂岩和大理岩作为研究对象,对激光入射频率和发次对烧蚀量的影响进行了初步研究。结果发现,烧蚀量与激光入射频率和发次有很大关系。此外,浸水后的烧蚀量明显大于干燥状态下的烧蚀量。

| Abstract: | The interaction between ultra-short laser pulses and rocks is an essential process in laser drilling well technology.It is determined by the rock components,ambient conditions,as well as laser parameters.The interaction of laser pulses with marble and red stone at different laser frequency and ablation shots are investigated.Results show that the mass loss is much related to laser incident frequency and ablation shots.Moreover,the mass loss is much higher in immersion water than in dry condition. |
