摘　　要：海洋可控源电磁法能识别高阻油气藏,可大幅提高钻井成功率。以Archie公式和Gaaamann公式为基础,建立油气储层的岩石物理关系,并将其引入目标函数,采用模拟退火结合粒子群算法的优化反演方法进行一维海洋可控源电磁和地震数据联合反演,直接得到储层孔隙度和饱和度参数。数值模拟反演结果表明,该算法不依赖初始值,反演效果好。Marine controlled source electromagnetic(MCSEM)can detect directly hydrocarbon reservoirs with high resistivity.To get reservoir characteristics,we put forward in this paper a joint inversion of 1D marine controlled source electromagnetic with seismic data.We first establish the relationship between reservoir parameter based on Archie's equation and Gassmann's equations,and then introduce the relationship into the objective function for joint inversion of 1D MCSEM with seismic data using a cooperative algorithm based on simulated annealing and particle swarm optimization.This inversion can directly obtain reservoir porosity and saturation.Tests on model data show that the proposed inversion can achieve good results without dependence of initial value.
