- W2393781569 abstract "The accurate prediction of strata pressure is the base for safely,qualitily,and efficiently drilling,decreasing hole problems and reasonable development of the reservoir.Because of the high cost,long cycle of the formation pressure measured method,which may influences the safety of drilling operation,thus a new method for predicting strata pressure,based on the BP neural network,is presented,and establishing process of the neural network forecast model are discussed in detail.This method takes the acoustic time,natural potential,natural gamma ray log data and pipe pressure test data as study sample,which has a very high accuracy.Strata pressure of the Saertu oil field and Xingshugang oil field in Daqing is predicted,and the results show that relative error between the predicted data and experimental data is less than ±8.9%." @default.
