Convertible Geometry Studies

Abstract

Summary For the seismic acquisition equipment tech to develop, and the great progress in nodes technology, the cost of acquisition equipment is continuously decreasing, so that it is possible to apply the large-scale application of acquisition equipment for geophysical exploration. This seismic acquisition method will become a seismic data acquisition trend. How to fully utilize a large number of acquisitions equipment to obtain large scale offsets, full azimuth angle seismic data is a new challenge. It can provide sufficient raw seismic data by using Convertible Geometry in seismic acquisition. In the follow-up seismic data processing, according to different geological targets, the relevant processing methods are applied to the acquired seismic data, and those seismic data has gotten by convertible geometry, which can get higher quality seismic images. For seismic data acquired by simultaneous multi-source with convertible geometry, simultaneous multi-source acquisition deblending separation technique and seismic wavelet inversion will be used in seismic data processing. Compared the seismic data by different geometries, the images of geological structures by convertible-geometry will be more accurate. The convertible geometry acquisition method is highly efficient, cost-effective, full azimuth. It can bring high-quality image of underground geological structures.
