| Abstract: |
| The basic principle and inionmilion treatmeni methods of seism while drilling SWD) technology in field were introduced, and the theoretical calculation model of formation pressure by SWD data was given. Interacted with the field application in a test well, the application of SWD technology on overpressure forecast and how to use SWD treatment result to give foundation for choosing casing setting depth were elaborated- The application result indicates that the overpressure and buried depth underground could be forecafiled by SWD technology, which can provide important basis for choosing casing setting depth in exploration well. |
| Key words: SWD technology interval velocity formation pressure casing setting depth |
