Based on the newly obtained cognition on lost circulation mechanisms of drilling liquids in carbonate formations, the authors established a lost circulation pressure model suitable to different leakage in carbonate formations, such as fracturing leakage, fracture expansion leakage and large-scale fracture or cavern leakage. The result derived from the model is relatively consistent with the actual situation and consequently provides a substantial basis for a rational design of the drilling fluid density as well as the leak resistance and sealing. Therefore, it is suggested that the design of drilling engineering should take the lost circulation pressure into consideration.
