摘　　要：依据地震资料反演的理论基础和实验方法,对高质量的地震资料运用strata软件进行了反演,并运用两边井(01—08、09—08、29—08)进行建模,中间未参与建模的井(08—08)进行反演结果对比的方法,进行了一系列实验,通过对反演结果与未参与建模井的测井曲线的对比,分析了初始猜测模型、反演方法、参数(子波)选择对反演精度的影响。Based on the theory and practices of seismic data inversion,this paper applied inversion to high quality seismic data with strata software and conducted a series of experiments by comparing the inversing results of the modeling wells on both sides and the logging curves of wells in the middle which didn't participate in the modeling.The differences in the data helped the paper analyze the impact the diverse choices of original assuming model,inversion method and parameter(wavelet) may have on the accuracy of inversion.
