| Abstract: | The casing failure accident is very common in geothermal drilling during casing and drilling after well consolidation. Analyzed casing failure causation in different stages and put forward treatment principle, also discussed causation and preventing measures. To use a typical ease study introduced treatment procedureto determine casing failure position through televiewer, make a centralizer, casing secondary casing then consolidating by cement. |
