Prediction and treatment of casing failure in cementing

Cementing operations are continuous and compact. If casing quality failure occurs during cementing operation, there is no sufficient time to analyze it in detail. If the judgment is wrong, it will bring huge uncertainties to the upcoming operation works. According to the recent casing failure problem, some pertinent treatments are put forward, combined with real operation cases. The study provides reference for judging and treating some abnormal problem during cementing operations.
