Abstract:  Lost circulations are common when drilling surface casing section at Changning shale gas block. By analysis of the loss data during surface drilling, the well loss features at the block are known and the plugging results are evaluated. Suggestions are given regards the EM geologic survey, casing program optimization, optimal drilling pattern, etc. , to minimize or control the lost circulations, expecting to provide guide and suggestion for Changning shale gas drilling. 

Key words:  , Changning shale gas, surface drilling, lost circulation, environmental protection, casing program
