【摘要】：地震照明分析对观测系统设计具有重要意义。本文在局部相似属性基础上研究了数据依赖的地震数据照明分析方法。首先分析局部相似属性的物理含义,给出数据依赖地震照明度分析方法;将采集的地震数据进行处理得到共成像点道集数据,利用局部相似属性计算不同炮检距的照明强度,从而得到数据依赖的照明分析。该方法不需要地质模型的假设,充分利用实际采集地震数据,估算不同炮检距(或入射角)对目标地质体的照明度。利用数据依赖地震照明分析结果可及时调整、改进设计后续地震勘探数据采集观测系统。
[Abstract]:Seismic lighting analysis is of great significance to the design of observation system. In this paper, based on the local similarity attribute, a data-dependent illumination analysis method for seismic data is studied. Firstly, the physical meaning of local similarity attribute is analyzed, and the method of data dependent seismic illumination analysis is given. The collected seismic data are processed to obtain the common imaging point gather data, and the local similarity attributes are used to calculate the illumination intensity of different offset, and the data-dependent illumination analysis is obtained. This method does not need the hypothesis of geological model and makes full use of the actual seismic data to estimate the illumination of the target geological body with different offset (or incident angle). The data dependent seismic lighting analysis results can be adjusted in time to improve the design of subsequent seismic exploration data acquisition and observation system.
