Abstract:

The vital technological breakthroughs in horizontal drilling and multi-stage hydraulic fracturing have promoted a great leap in the development of the shale oil and gas industry and profoundly reshaped the global energy landscape. This study reviewed the latest technological advances in horizontal drilling and well completion for shale oil and gas both in China and internationally. A comprehensive comparative analysis was conducted across the casing program,rotary steering,automated drilling rigs,intelligent drilling,high-performance drilling fluids and lost circulation prevention and control,as well as fracturing equipment and monitoring technologies. The drilling time,horizontal wellbore length,and "one-trip" ratio in China showed considerable room for improvement,compared to those abroad. Therefore,efforts of research and development shall be strengthened for automated drilling rigs,next-generation rotary steering tools,high-efficiency polycrystalline diamond compact(PDC) bits,high-torque screws,and multi-stage fracturing and monitoring technologies,to enhance the "one-trip" ratio of long horizontal wellbores and boost production per well,promote the digital and intelligent transformation of drilling and completion technologies in China,and provide strong technical support for China's shale oil and gas revolution. 

Key words:
