在众多的井下动力钻具类型中,单螺杆钻具是比较典型的钻具类型,这种设备在工作的过程中主要是以容积式马达结构为主。其特点比较突出,不仅可以实现压力泥浆驱动,而且设备的结构相对比较简单,最重要的是其外形结构具有一定的特殊性,可以在钻井作业中得到广泛地应用。在具体的实践和研究中,工作人员对这种新型的井下动力钻具进行了细致地分析。 Among the many types of downhole power tools, single screwdrivers are the typical type of drilling tools. During the working process, this type of equipment mainly uses positive displacement motor structure. Its characteristics are more prominent. It not only can realize the pressure-driven mud, but also the structure of the equipment is relatively simple. The most important thing is that its shape and structure have certain peculiarities and can be widely used in drilling operations. In the concrete practice and the research, the staff carried on the detailed analysis to this new underground power drill.
