摘要:
随着国内外各大油田勘探开发的深入,宽方位高密度三维地震得到广泛应用。在计算机处理能力快速发展的驱动下,OVT域偏移处理技术进一步推广应用于油藏描述领域,特别是螺旋道集在碳酸盐岩缝洞型油气藏连通性分析方面的应用越来越广泛。本文提出一种基于OVT道集的裂缝预测模板自动优化方法,通过道集品质分析、方位角与炮检距初分析、裂缝预测模板自动优化等一系列流程,快速迭代并自动优化最优方位角与炮检距参数方案,提供后续裂缝计算。该方法大大缩减了对比分析不同参数方案计算结果的所耗机时,同时使得求取较好裂缝预测结果的繁琐工作流程得到简化。
Abstract:
With the deepening of exploration and development of major oilfields in China and abroad, the wide azimuth and high-density 3D seism has been widely applied. Driven by the rapid development of computer processing capacity, the OVT domain migration processing technology is further applied to reservoirs description, especially the application of spiral gathers in the analysis of carbonate fractured-vuggy reservoir connectivity, becoming more and more widely. In this paper, it is proposed an automatic template optimization method for fracture prediction based on RBF algorithm. Through a series of processes, such as the quality analysis of the gather sets, the initial analysis of the azimuth and the offset, and the automatic optimization of the fracture prediction template, the optimal azimuth and the offset parameters are automatically optimized, and the subsequent fracture calculation is provided. This method greatly reduces the time consuming of comparison and analysis of the calculation results of different parameter schemes, and makes the complicated work process of finding the better fracture prediction results simplified.
