摘要
分析了以两根螺杆钻具串联而成的组合钻具的工作特性及转矩、压降、排量、轴向力等问题。讨论了涡轮－螺杆串联组合钻具的工作特性和匹配问题，并将涡轮钻具、螺杆钻具和涡抢－螺杆串联组合钻具的特性进行了对比，指出在井下动力钻具尚以螺杆钻具为主的我国，不宜发展串联组合钻具。
The authors analyze the operational performance, torsion, pressure drop, displacement and axial force of a compound downhole drill comprised of two serially connected screwdrills, discuss the operational performance of a serially connected turbodrill and serewdrill and their matching requirements, compare the characteristics of turbodrill, screwdrill and turbo-screw compound drill, and point out it is inadvisable to develop the compound drill in China where screwdrills are still successfully used.
