综合应用重磁对应分析和重磁联合反演的基础上提出对重磁联合反演的一种改进方法:约束联合反演,即利用重磁异常相关系数对联合反演中目标函数进行加权。实验结果表明,该方法有利于迭代反演的收敛性。把该方法应用于塔里木盆地东部库尔勒~若羌剖面,结果说明,以对应分析的结果作为先验认识,有助于合理地建立最优化反演的初始模型,能提高解释结果的质量。
Based on the application of the analysis of gravity and magnetism and the combination of gravity and magnetic inversion, an improved method is proposed for joint inversion of gravity and magnetic flux. Constraint joint inversion is used to weight the objective function in joint inversion using correlation coefficients of gravity and magnetic anomalies. Experimental results show that this method is good for the convergence of iterative inversion. Applying this method to the Korla-Ruoqiang section in eastern Tarim Basin, the results show that using the corresponding analysis results as a priori knowledge helps to establish the initial model of optimal inversion reasonably and improve the quality of interpretation results.
