为了加快复杂地下介质中油气的寻找，针对单相流体多孔介质，提出了基于EPPM（Equivalent Model of Porous Media）和地震CT的小生境多参数反演算法。该算法综合了电磁波传播理论、Radon变换和小生境遗传算法，并将接收信号与遗传群体相结合。理论分析和反演结果表明，该方法可以有效地避免复杂的波动方程求解。该方法计算简单，精度高，能较好地解决威尔斯井间地层成像问题。
In order to quicken the search for oil and gas in complicated underground media, the niche multi-parameter inversion algorithm based on EMPM (equivalent model of porous media) and seismic CT is proposed for porous media full of single-phase fluid. The algorithm integrates EMPM theory, Radon transformation and niche genetic algorithm and connects received signals with genetic colony. The theoretical analysis and inversion results indicate that the method can effectively avoid sophisticated solution of wave equations. The solution is easy to derive with high accuracy and can settle the problem of strata imaging between wells.
