摘要

In order to explore the 3D seismic acquisition technology of different complex surface and underground structures in Ordos Basin, and provide high quality seismic acquisition data for oil and gas exploration in the basin; The signal-to-noise ratio and resolution of the acquired data can be ensured by the experiments, the design of the acquisition method, the optimization of the excitation and reception method, and the uniform distribution of the high-definition aerial images. Three-dimensional seismic acquisition single shot record data and section signal-to-noise ratio, resolution and integrity meet the technical requirements of oil and gas exploration, and the main frequency is increased by 9 to 30–33 Hz; The three-dimensional technology series with “wide-azimuth, broadband and high-density” as the core is gradually determined through the test production, which provides the basis for deepening the three-dimensional seismic acquisition technology in the basin step by step and effectively supports the great development of oil and gas exploration and development in the basin.
