摘要
针对激光技术在石油工程技术领域的应用,国内学者开展了大量理论研究,为了验证理论分析和激光破岩实际效果,搭建了激光试验系统,开展了硅质砂岩岩样激光直线扫描及定点打孔试验,分析得出激光破岩效果与激光光束参数、扫描速度、光斑尺寸及岩屑清理等因素相关。根据激光扫描和打孔试验结果,有针对性地提出了气体钻井激光辅助破岩和激光射孔2方面应用,并重点从激光光源优选、高能激光远距离传输及井下适应性3个方面分析了激光应用需要解决的关键技术。所得结论对激光技术在石油工程领域应用具有重要的指导意义。
Domestic scholars have carried out a lot of theoretical researches on laser technology application in petroleum engineering field. To verify the theoretical analysis and the actual effect of laser rock breaking, a laser- rock test system has been established. The laser linear scanning and fixed-point hole drilling experiment has been conducted on the siliceous sandstone. The results show that the laser rock breaking performance is influenced by factors like laser beam parameters, scanning speed, spot size and cutting debris cleaning. According to the scanning experiment and the hole drilling experiment, laser assisted gas drilling and laser perforation application in petroleum engineering are proposed. The key technologies of laser application have been analyzed in three aspects： laser source optimization, high energy laser long-distance transmission and laser application downhole adaptability. The study results could provide guidance to the application of laser technology in petroleum engineering.
