【摘要】 在井资料、地震资料等先验知识的约束下 ,采用非常快速的模拟退火算法对起伏地形的连续电磁阵列剖面(CEMP)资料进行非线性约束反演。理论模型试算表明了方法的正确性及有效性。CEMP2 6 8测线实际资料的反演补充了钻井、地震资料的不足 ,提供了该区重要的生、储层——中生界的厚度及分布 ,为地质人员提供了重要的基础性数据。更多还原

【Abstract】 Fast simulated annealing arithmetic is adopted to realize2 D non linear constrained inversion of MT data with uneven topography.Theoretic model test showed the correctness and effectiveness of the method.The inversion has been performed for real data on line CEMP 268 in Yiqikelike region in a constraint of a priori knowledge such as borehole and seismic data etc.,supplementing the shortage of drilling and seismic data and providing the thichness and distribution of Mesozoic layer—important source rock and reservoir of the region,which provided an important basic data for geologist.更多还原
