| Abstract:The failure of anti-friction rings on drilling pipes at Northern Erdos Work Areas is very in common. The main causes of the failures of the anti-friction rings on drilling pipes are formation abrasion, downhole performance conditions of drilling pipes, selection of high-abrasive materials, and welding techniques. It is very important to resolve the problems of anti-friction ring failure due to partial worn at Northern Erdos Work Areas by reasonable selection of high-abrasive materials and welding techniques. |
