摘要
钻井是能源矿产勘探开发最直接的工程技术手段,井下动力钻具作为破碎地层岩土的有利器具,或直接驱动钻头形成滑动钻进,或与顶驱(或转盘)的回转共同组合驱动钻头形成复合钻进,具有降耗增速、减小井下事故风险等优点。为促使井下动力钻具被更多技术人员了解和认识,物尽其用充分发挥其钻井优势并利用技术特点开发新功能、新器具,本文从科普的角度介绍了井下动力钻具的用途、主要种类、工作原理及发展历程,并综合对比不同井下动力钻具的优劣势。最后,结合深井、超深井等钻井新形势对钻探器具、工艺等的新要求,以及材料、测控、智能化等新科技的在钻井工程中的应用趋势,指出了当前主流井下动力钻具的更新换代、技术革新的发展方向。
Drilling is the most direct engineering technology means for the exploration and development of energy and mineral resources.As a powerful tool for breaking rock and soil,downhole power drilling tool have the advantages of reducing consumption and increasing drilling speed,as well as reducing the risk of downhole accidents,it either directly drives the bit to form sliding drilling,or combines the top drive(or rotary)to form composite drilling.In order to prompt more technical personnels to understand the downhole power drilling tool,and develop new functions and new instruments based on its drilling advantages and technical characteristics,this paper introduces the use,main type,working principle and development history of the downhole power drilling tool from the perspective of popular science,and compares the advantages and disadvantages of different downhole power drilling tool.Finally,combined with the new requirements posed by the new drilling situation of deep wells,ultra⁃deep wells on the drilling tool,techniques and so on,as well as the application trend of other new technologies in drilling engineering such as materials,measurement and control,intelligence,etc.,it pointed out the upgrading and technological innovation development direction for the current mainstream downhole power motor.
