Major breakthrough in shale gas survey in new Wendi 1 well of electric top drive rotary drilling rig
In September 2017, the new well 1 well, Wensu County, Shandong Province, was drilled by the third geological and Mineral Exploration Institute of Xinjiang province. The XD-40DB/P type electric top drive rotary drilling rig developed by Zhong Zhuang Group Co., Ltd. is used in the project. This type of driller adopts frequency conversion electric drive technology to realize digital control, display and monitoring. According to the need of drilling technology, it can be used as an independent electric frequency conversion top drive drill or as an electric frequency converter drill. It mainly includes seven components, such as the main components of the variable frequency main winch (including the automatic drilling device), the top drive system, the turntable system, the mud pump, the independent driller room, the general electric control room and the drill tower. It has realized a variety of functions, and can better meet the oil and gas investigation wells, the parameter wells, the geothermal wells, the water wells and the shallow well oil wells. The requirement of caliber drilling is the first choice for geological prospecting units to cross boundary transformation of unconventional oil and gas exploration.
