adjustment is performed via the time-break sensor method Explanation: This is the closest concept I could find in English literature that deals with adjustment of seismic source point arrays. cccccc Seismic source array calibration and synchronization method, apparatus and system WO 2014006212 A3 ABSTRACT Method, apparatus and system for calibrating and synchronizing a seismic acoustic source array (50) by taking into account both a time- break signal (500) and a near-field signal (504). A time delay between the time-break signal and the near-field signal is used to calculate an offset for adjusting the shooting of the source elements of the source array. http://www.google.jp/patents/WO2014006212A3?cl=en cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc One approach to quantifying the mechanical triggering delay is to use a time-break sensor. The time-break sensor is positioned inside or proximate the acoustic source element, e.g., air gun, and a specific attribute is detected in the signal measured by the time-break sensor. For example, the attribute may comprise signal maximum amplitude, time of threshold, zero-crossing, or other suitable attributes. The time delay between sending the firing signal and the time of the detected attribute in the time-break signal is processed via a firing control algorithm to adjust the time of the next firing signal. [0004] However, acoustic source element synchronization using air gun mounted time-break sensors provides only an indirect way of synchronizing the peak pressure of the emitted acoustic signals. https://www.google.ch/patents/US20120218860?hl=de |
