据美刊油气杂志一九七七年十月三十一日号报导。对气穴喷射钻井技术正在进行系统的系列试验,首先试验此项技术的可实现性,然后论定用以增强深井钻头机械切削作用的气穴水力喷射技术的有效应用。气穴喷射是一种紊流喷射,它从容地激发蒸气和气体腔穴以增强比较低速的液体喷射的冲蚀作用。 According to the American Journal of Oil and Gas, October 31, 1977 report. A series of systematic experiments on cavitation jet drilling are underway. The feasibility of this technique is tested first, and then the effective application of cavitation hydraulic jet technique to enhance the mechanical cutting action of deep well bits is discussed. Cavitation jetting is a turbulent jet that gently excites the vapor and gas cavities to enhance the erosion of the relatively low velocity liquid jet.
