| Abstract:Incomplete casing, case breaking, drilling rod cementing and case collapsing often occur in the construction of large diameter coal mine gas emission well, ice transmission cooling-well, nitrogen injection well and feeding well in China in recent years. The paper analyzed the failure causes according to the study on common accident of large diameter project well, and put forward the prevention measures. |
