摘要： A seismic vibrator for obtaining a true ground force includes a baseplate pad; a baseplate drive system, the drive system is connected to the baseplate pad and moves the baseplate pad up and down; a vibrator controller electronics, the electronics are connected to the drive system and causes the drive system to move the baseplate pad up and down; and a plurality of load cell sensors disposed between the baseplate pad and ground, the sensors measure the vibrator output force during a sweep. A true ground force sweep includes using the load cell sensors to measure an actual output force of a seismic vibrator and electronics to obtain an actual ground force data; using inversion to invert the actual ground force data and desired original pilot sweep to obtain a revised pilot sweep that produces a true ground force sweep; and entering the true ground force sweep into the electronics

摘要： The invention relates to continuously or near continuously acquiring seismic data where at least one pulse-type source is fired in a distinctive sequence to create a series of pulses and to create a continuous or near continuous rumble. In a preferred embodiment, a number of pulse type seismic sources are arranged in an array and are fired in a distinctive loop of composite pulses where the returning wavefield is source separable based on the distinctive composite pulses. Firing the pulse type sources creates an identifiable loop of identifiable composite pulses so that two or more marine seismic acquisition systems with pulse-type seismic sources can acquire seismic data concurrently, continuously or near continuously and the peak energy delivered into the water will be less, which will reduce the irritation of seismic data acquisition to marine life.
摘要翻译：本发明涉及持续或接近连续采集的地震数据，其中至少一个脉冲型源以特定的序列发射以产生一系列脉冲并产生连续的或接近连续的隆隆声。在优选实施例中，多个脉冲型地震源被布置成阵列，并且在复合脉冲的独特环路中发射，其中基于特征复合脉冲，返回波场是源可分离的。发射脉冲型源产生可识别的可识别的复合脉冲循环，使得具有脉冲型地震源的两个或更多个海洋地震采集系统能够连续或连续地获取地震数据，并且输送到水中的峰值能量将较少，这将减少对海洋生物的地震数据采集的刺激。
