精确的叠前分析取决于高质量的地震数据。地震数据体应组织成地震道集,这些道集根据一定范围的人射角对相同的地下区域进行采样,贯穿这些道的反射波形变化取决于反射边界上的岩石特性和流体状况。而且信噪比(S/N)应较高,足以精确地检测出波形变化和任何异常的特征。处理方案的目的就是得到这种形式的数据,而不引入任何人为假象。因此,影响叠前数据质量的主要因素可以分解成信噪比(S/N)、对共反射点道集的成像、横向和垂向分辨 Precise prestack analysis depends on high-quality seismic data. Seismic data volumes should be organized into seismic traces that sample the same subsurface regions based on a range of angles of incidence. The reflected waveforms across these traces depend on the rock properties and fluid conditions at the reflective boundary. And the signal to noise ratio (S / N) should be high enough to accurately detect the waveform changes and any unusual features. The purpose of the solution is to obtain this form of data without introducing any artificial illusion. Therefore, the main factors that affect the quality of prestack data can be decomposed into S / N, and the imaging, horizontal and vertical resolution of common reflection point gathers
