In recent years,the number of high temperature and high pressure wells drilled in the eastern South China Sea has gradually increased,which has seriously affected the safety of drilling and data acquisition.In this paper,an A1 exploration well of a structure in Huizhou was completed in advance due to over-pressure formation,and the cause analysis of high pressure was introduced.A2 was redeployed to carry out fine prediction analysis of formation pressure before drilling.The pressure coefficient of the target layer was predicted to be between 1.500 and 1.600,and the successful drilling of A2 well was guided.The measured pressure coefficient of MDT is 1.595,which realizes the xploration purpose.
