    Abstract：In order to shorten intermediate stop time during well site preparation, rig relocation and equipment debugging, improve drilling efficiency, implement “standard, efficient and quick” drilling operation and reduce the cost of comprehensive development, Changqing Oilfield began the factory-like drilling pattern development test of “big cluster well group well spacing and assembly line engineering work” in 2013. In view of technical difficulties in the factory-like drilling, applied are such 3d horizontal well drilling technologies as well bore profile optimization, borehole trajectory control, friction reducing and drag reduction, crash-proof winding obstacle and G 0-7 factory-like drilling task is successfully completed, which has accumulated valuable real drilling experience and will provide technical supports for future large-scale factory-like drilling.
