钻杆接头结构型式首先取决于拧卸方法，其次是采用什么样的提引器。从目前国产水文水井钻机情况看，钻杆的拧卸都是利用转盘进行的，但是由于拧卸机构各不相同，因而出现钻杆接头和提引器达三、四种之多。这和岩心钻探、工程地质钻探、石油钻探相比，应该说是一个比较大的问题。如果这个问题不解决，一是不能组织专业化生产、保证加工质量；二是给用户带来许多麻烦；三是给以后钻机配套出口造成困难。能否改变一下目前的拧卸方法，使钻杆接头和提引器尽可能地统一起来？对此，谈谈自己的意见。 Drill pipe joint structure type depends first on the unscrewing method, followed by what kind of lift device. From the current situation of domestic hydrological well drill, drill pipe screwing is carried out using the turntable, but due to screwing mechanism varies, resulting in drill pipe joints and lift up to three or four. This is compared with core drilling, engineering geological drilling, oil drilling, it should be said is a relatively large problem. If this problem is not solved, firstly, it is impossible to organize specialized production to ensure the quality of processing; secondly, to bring many troubles to the users; thirdly, to give difficulties to the export of drilling rigs afterwards. Can change the current screwing method, the drill pipe joint and the lifting device as uniform as possible? In this regard, talk about their own opinions.
