DEVICES, SYSTEMS AND METHODS FOR MEASURING BOREHOLE SEISMIC WAVEFIELD DERIVATIVES |
摘要 |
The disclosure provides devices, systems and methods for obtaining unaliased wavefield data despite using spatial sampling distances that are higher than conventional techniques and temporal sampling rates that are lower than conventional techniques. The devices can include an array of sensors for sampling a desired wavefield and at least one of its derivatives. The systems can include a multi-level array of such sensor configurations. The methods can include lowering such an array into a borehole and sampling data at distances that are greater than suggested by conventional theory, or lowering a multi-level array into a borehole and simultaneously gathering data at different depth levels. |
