当今钻井技术不断发展,钻井设备装备技术的发展也是日新月异,交流变频顶驱的广泛应用就是其中之一。本文主要阐述了钻井顶部驱动系统的组成、分类、工作原理,以及它相对于传统钻井设备的优势;随着交流变频技术的发展,以及变频器的广泛应用,交流变频顶驱的发展与广泛应用也是趋势所在。最后针对该型号顶驱在现场中具体应用中存在一些问题和不足,提出一些新的设计思路。 With the continuous development of drilling technology and the ever-changing development of drilling equipment and equipment technology, one of them is the extensive application of AC variable frequency top drive. This paper mainly expounds the composition, classification, working principle of drilling top drive system and its advantage over traditional drilling equipment. With the development of AC frequency conversion technology and the extensive application of frequency converter, the development and application of AC variable frequency top drive It is also the trend. At last, there are some problems and shortcomings in the specific application of this type of top drive in the field, and some new design ideas are put forward.
