摘　　要：套管磨损和扭矩过大是钻深井、超深井、水平井和大位移井时一个不容忽视的问题。套管磨损破坏会引起卡钻、井漏、井口窜油气等事故 ,并可能给采油工作带来很多困难 ;钻柱扭矩过大会导致钻具损坏。为了保护套管和降低扭矩 ,可采用防磨接头。现文介绍了适用于套管的 FMX型和适用于裸眼的 FMJ型非旋转式防磨接头的结构原理、特点。Wear of casing and too large torque are problems which can't be ignored when drill deep and super deep well, horizontal well and deviated well. Too large torque of drillpipe will damage the drill tools, and casing wear will cause a lot of downhole problems. We can use wear resistance connections to prevent these accidents.This article introduces two types of wear resistance connections.One is FMX type,and another is FMJ type.
