| Abstract: | In the well Cheng-2 Nappe structure, the main lithologic is the granite of epi-Hercynain, the rock hardness is high, drilling operation is very difficult. This paper introduces the characteristics and the reasons of drilling tool failure, the judgment of downhole condition when drilling tool failure, fishing method of fish and prevention measure of drilling tool failure in drilling process of the nappe structure. These experiences can guide the drilling operation in nappe structure in future. |
