Seismic exploration method with enhanced survey results - has sensor array for sensing response of seismic horizons to emitted seismic waves |
摘要 |
<p>The method of seismic exploration includes sensing the response of the seismic horizons to emitted seismic waves, by using a sensor array of aperture of a number of seismic sensors. The sensor array or aperture is larger than the dia. of a circular region, termed the Fresnel zone for the deepest seismic horizon of interest in which all ray paths for seismic waves at a highest frequency of interest differ in phase by less than one-half wavelength. With an aperture of this size, the responses of seismic horizons sensed by the sensors differ from each other in phase by less than one-half wavelength. Individual sensors in the array are spaced from the next adjacent sensors by less than or equal to one-quarter wavelength of horizontally travelling seismic noise waves at the highest noise frequency of interest.</p> |
