摘要
本文对强激光应用于油气井下进行激光射孔作业进行了研究,对比了光纤激光器与二氧化碳激光器在破岩效率上的区别,并从数值模拟和实验两方面研究了岩石受激光照射后的温度场分布以及岩石内部孔洞形状的成因。
In this paper, I have researched how the high power laser is applied to do a laser perforation under the oil and gas well. And compared the distinguish of rock - breaking efficiency between the fiber laser and the carbon dioxide laser. I have also studied the distribution of rocks＇ temperature field after they are shined by laser and the reason of forming hole shape in rocks through the two parts of numerical simulation and experiment.
