Seismic detection apparatus and method |
摘要 |
A method of seismic exploration while drilling from within a borehole containing fluid, with a source and receivers positioned in the borehole is provided, comprising detecting small amplitude signals from waves within the fluid. The method is used to identify signals from waves within the fluid known as tube waves that result from compressional waves converted at the bottom of the borehole. The invention also includes seismic detection apparatus comprising ring hydrophones or similar pressure sensors. The apparatus is preferably attached to a coiled tubing with the drill bit actuated by a separate actuator as source.
