摘　　要：宽范围岩石物性约束方法具有容易实现,一定容错性的优点。但是,目前该方法是基于模拟退火算法或差分进化(DE)算法在L2范数条件下实现,能否扩展至其他范数、其他优化算法条件有待进一步验证。基于此,在L1范数条件下,分别实现了基于差分进化(DE)算法和人工蜂群(ABC)算法的大地电磁测深(MT)和重力宽范围物性约束联合反演。模型试验结果表明,岩石物性参数在一定范围内实现耦合。此外,宽范围岩石物性约束是适用于L1范数和ABC算法的,具有进一步扩展至其他范数、其他优化算法的潜质。The wide-range petrophysical constraints method has advantages of easy implementation,and certain fault tolerance.Currently,this approach is implemented based on simulated annealing algorithm or differential evolution(DE)algorithm in L2-norm.But whether it can be extented into other conditions of different norms using other optimization algorithms needs to be further verified.Thus,the joint inversion of magnetotelluric(MT)and gravity with wide-range petrophysical constraints in L1-norm is realized based on DE algorithm or artificial colony(ABC)algorithm respectively.According to model test results,the coupling of petrophysical parameters is promoted within a certain range.In addition,the approach,which has potential to be further extended to other norms and other optimization algorithms,is applicable to L1-norm and ABC algorithm.
