Abstract: The casing failure and its distributing in Zhongyuan oilfield was analyzed in the paper. It was concluded that the main reason of casing failure was not enough strength to resist the high collapse load in the salt-rock formation. The performance of the TP130TT high strength-thick walled casing was verified in the study, it is proved that the TP130TT casing would satisfy with the casing collapse strength of Zhongyuan salt-rock formation.

Key words: casing damage, salt bed, the casing, exploita-tion, application
