摘要
简要分析回顾了破岩和钻井方法的发展,论述了激光钻井和高压水射流钻井的发展潜力,阐明了高压水射流钻井技术已具备工业应用的可行性。分析了高压水射流破岩机理研究中的关键问题及解决途径,介绍了利用数值模拟和试验相结合的方法研究高压水射流破岩机理所取得的一些突破性进展,提出了建立和完善高压水射流破岩理论体系、发展水射流钻井技术的研究方向。
Based on the reviews of the development history of rock breaking methods and drilling technologies, it is point out that all the laser drilling technologies as well as waterjet drilling technologies have great potential in improving the drilling efficiency. The critical problems and their possible solutions of the rock breaking mechanism under waterjet were analyzed and discussed in detail, and then some new achievements in combined numerical simulation research and experimental research are introduced also. The future development direction of rock breaking mechanism under waterjet was presented from the point to built and perfect the theory system.
