摘　　要：对于底部加加重杆,上部加防磨扶正杆的偏磨井,下入杆柱过程中受到的摩擦力较大,加重杆的长度设计成为关键。对一般斜井和直井所需加重杆长度进行了分析和计算,并给出了计算方法。Heavy rods at the bottom of suck rods are used to help the rod system move downwards in one-side attrition wells where we use anti attrition centralizing rods. Frictional resistance to the rod system is so big that the length calculation of heavy rods becomes very important. The traits of the rod system are analyzed and the normal calculating method in both slant holes and straight holes is given.
