南非使用盲井钻机已有12年历史了,拥有一、二、三代钻机37台,很快就会出现第四代。1974年以来,研究与开发服务公司一直从事其使用和开发工作。三年前,该公司订购了一台罗宾斯52RE 型高压水射流辅助的盲井钻机,并与罗宾斯公司和流体工业公司一道,在科罗拉多矿业学院对该机作了改进研究。一致认为,高压水射流的好处是可减少所需的推力和扭矩,从而可显著减少刀具的 Blind rigs have been used in South Africa for 12 years and have 37 first-, second-, and third-generation rigs and the fourth generation will soon emerge. Since 1974, research and development services companies have been engaged in their use and development. Three years ago, the company ordered a Robbins 52RE high-pressure water-jet blind well rig and worked with Robbins and Fluid Industries to refine the aircraft at the Colorado School of Mines. It is agreed that the benefits of high pressure water jets are to reduce the thrust and torque required, which can significantly reduce the tooling
