Abstract:

The H Oil Field of the Tarim Basin is developed with the ultra deep horizontal well.In recent years,the phenomena of the casing failure has been increasing,resulting in the difficulties for the production.Pointing to the situation,effort is made to conduct multidisciplinary research on the damaged casing plane and the law of the longitudinal distribution.Research is also done on the physical and chemical mechanism in priority,the research clue of the casing damage "precaution,diagnose,treatment" technology is proposed by combining the reservoir engeneering,drilling,logging and down hole operation technology.The practice demonstrates that the forecasted casing damage wells are unanimous with the actual wells,and the recover ratio is high,which successfully seeks for the countermeasure technology for the casing failure in the ultra deep horizontal well,offeres the consults for other oilfields which have the analogous problems.

Key words: Tarim, horizontal well, casing failure, mechanism, precaution, diagnose and treatment
