| Abstract: | The paper has introduced development history of water well drilling rigs briefly and general situation,technical features at present. Through performance comparison of home and abroad,analyzed technological gap of rotary table water well rigs between Chi-na and abroad. Combined with fully hydraulic top drive water well rig technical characteristics,have advised to develop multifunction-al fully hydraulic top drive water well rig can greatly narrow the gap,thus the development orientation of water well rig in China. |
