摘要
介绍了多分量地震资料波阻抗反演方法,特别是转换波资料波阻抗反演的原理和方法。应用多分量波阻抗反演技术,对纵波和转换波地震资料进行了波阻抗联合反演,获得了纵波和横波波阻抗剖面、纵横波速度比剖面、λρ剖面、μρ剖面以及各种岩性参数交会剖面。利用这些成果,可以得到比常规波阻抗反演更准确、更丰富的储层信息,在目标储层的含气性识别中取得了很好地效果。
This paper discussed the wave impedance inversion on multi-component data with emphasis on the principles and methodology of wave impedance inversion for converted waves.Joint wave impedance inversion for P-and converted waves was carried out on multi-component data.Sections such as P-and S-wave impedance,velocity ratio of P-and S-wave,λρ,and μρ,as well as crossplotting sections of different lithological parameters were generated.The results were then used to predict the gas potentials of reservoirs.Desired results have been achieved as more accurate and more plentiful reservoir information than conventional P wave impedance inversion was used in reservoir prediction.
