一、钻杆接头的作用钻杆本身配带的接头统称钻杆接头。钻杆接头是成对使用,即一根钻杆两端分别配上一个公接头,一个母接头。其主要作用是连接钻杆,保护钻杆管体不被磨损及在钻井作业中便于装卸。一根钻杆在钻井中,一般是公接头在下端,母接头在上端。二、钻杆接头的种类钻杆接头可分为有细扣钻杆连接的接头(见冶标528—65石油钻探管和沪QJB370—66标准工具接头)和无细扣对焊钻杆连接的接头(见冶标691—70)两种,有细扣钻杆连接接头的一端为细母
First, the role of the drill pipe joints The drill pipe itself with the joints are collectively referred to as drill pipe joints. The drill pipe joints are used in pairs, that is, one drill pipe is equipped with one male connector and one female connector at both ends. Its main role is to connect the drill pipe, protect the drill pipe body from wear and facilitate loading and unloading in drilling operations. A drill pipe is in the well, usually with a male connector at the bottom and a female connector at the top. Second, the type of drill pipe joints Drill pipe joints can be divided into fine joints connected with the drill pipe joints (see the metallurgical standard 528-65 oil drilling pipe and Shanghai QJB370-66 standard tool joints) and no fine button welding drill pipe connection Joints (see Mic standard 691-70). There are fine females on one end of the drill pipe connection connector.
