基于随机分布共网格模型的重磁电震联合反演技术及应用
Keywords: 重力,大地电磁,地震,网格模型,正则化,联合反演
Abstract:
？针对重力、大地电磁与地震资料联合反演存在的精度和稳定性问题,应用以下技术:①基于统一物性随机分布共网格模型的建模技术;②通过改进地震走时的二维射线追踪计算方法以适用于复杂地质模型;③引入tikhonov正则化思想至反演中,并加入先验信息进行模型约束,实现重、磁、电、震同步联合反演;④通过模型试验的对比分析对关键参数进行优化;⑤采用完全非线性的全局寻优模拟退火算法,以提高解决复杂问题的能力.实际应用效果表明,加入有效模型约束的正则化联合反演,可以提高反演的稳定性和计算精度,获得更接近实际的结果.
