摘要
Seismic inversion is the hotspot of the prediction of oil and gas,which can change the information of reflection interface expressed by seismic data into information of reservoir parameters including directly geological significance,so it has attracted a lots of geological researchers.Post stack seismic random inversion has significant advantages in reservoir description,which takes the lateral resolution of seismic data and the vertical resolution of logging data into account.In this paper,for the study of reservoir of the oil group of ZJ2-1 in Wenchang A oil field,we select the average wavelet of multiple wells,establish the low-frequency model,and determine the function of level variation using the constrained sparse spike inversion and the function of vertical variation by the analysis of log data based on the analysis of lithology characteristics of the reservoir,and take the seismic random inversion.The good results are achieved in the study of reservoir heterogeneity.
