Land Equipment for Broadband Seismic Data Acquisition and the Application

Broadband, wide azimuth and high density data acquisition are ever growing trend of seismic exploration in recent years. Conventional acquisition equipment and geometry scheme have been unable to meet the technical requirements for this development. With the reliability of modern electronic equipment greatly improved. On the premise of ensuring production efficiency and reducing acquisition cost, the updated seismic acquisition equipment makes high-density acquisition possible and meets the needs of deep exploration and high-precision exploration. This paper focuses on the technical improvement of land seismic acquisition of vibrator (Nomad series) and digital sensor (dsu1-508) and analyses the processing seismic results of high-density acquisition compared with that of conventional acquisition. The results showed that the new generation of equipment greatly improved the imaging quality while widening the frequency band and improving the resolution.
