| Abstract: | The failures of abrasion resistant ring on drilling pipes are common during drilling in Daniudi Area. After Analyses and research, it was thought that the main facts which affect drilling pipe abrasion resistant ring failure were abrasive property of formations, selection of high-abrasive material, and wielding technique. |
