In order to reduce the difficulty of handling complex cases and reduce losses,conventional drilling BHA are usually used to log data after safely drilling.According to the dc index PreVue formation pressure monitor,it is difficult to meet the requirements of drilling guidance due to the lack of reference data of LWD data.Therefore,the formation pressure monitoring method based on specific energy of drilling machinery is put forward to analyze and predict the change trend of formation pressure,to give early warning of abnormal high pressure risk,and to guide drilling engineering to take effective preventive measures.This monitoring method has been successfully applied to predict the abnormal high pressure before drilling in the Beibu Gulf exploration well,which provides more adequate guarantee for safe and efficient drilling.
