Development and Application of Downward Prediction Technology of Real-time Formation Pressure in Formation Pressure Monitoring Process
Accurate monitoring of formation pressure is crucial in narrow window drilling operations.Before drilling operations,it is necessary to determine the safe density window for drilling operations.Due to the complexity of formation pressure and geological structure,there is a certain deviation between the pre-drilling formation pressure prediction and the monitored formation pressure.During the actual drilling process,the actual formation pressure will be higher or lower than the pre-drilling model prediction.If not handled properly,it can cause problems such as overflow or leakage.This article introduces a new technology for predicting formation pressure in real time.By fitting the pre-drilling model with the monitoring results to correct the formation test pressure data,the accuracy of the pre-drilling model is improved,and the technology has been applied to the section to be drilled.This technology has achieved good application results in on-site construction and can provide reference for real-time prediction of formation pressure in the future.
