摘　　要：“璇玑”系统是中海油服自研旋转导向及随钻测井系统,目前已经完成1000口井的作业。为了使“璇玑”系统保持竞争力并得到进一步推广,“璇玑”系统配接的钻头选型至关重要。基于“璇玑”系统导向工具的结构特征和导向机理,阐述钻头选型的原则和方法,从“璇玑”系统应用角度提出适合该系统应用的钻头选型方法,并通过实钻实验分析得到钻头选型的特征参数,从而总结出“璇玑”系统在钻头选型方面的原则,可为“璇玑”系统推广应用提供技术参考和理论依据。“Xuanji”system is a self-developed rotary steerable system and logging while drilling system in China Oilfield Services Limited.At present,1000 wells have been operated.In order to maintain the competitiveness of“Xuanji”system and be further popularized,it is very important to select the bits matched with“Xuanji”system.Based on the structural characteristics and guiding mechanism of the guiding tools of“Xuanji”system,the principles and methods of bit selection are expounded,puts forward a bit selection method suitable for the application of“Xuanji”system.Through the analysis of actual drilling experiment,the characteristic parameters of bit selection are obtained,and the principles of bit selection in“Xuanji”system are summarized.It provides a technical reference and theoretical basis for the popularization and application of the“Xuanji”system.
