| Abstract: |
| The influnce of fluid parameters' variation on seismic elastic parameter and seismic record were researched on the basis of theoretical model. And then prestack amplitude variation with angle(AVA) elasticity inversion was carried out by using Shengli block's real data. Based on inversion and amplitude variation with offset (A VO) analysis, different attributes of fluid characteristic were extracted and reservoir fluid characteristics on profile and plane were predicted. The inversion results agree well with reai well-drilling data, which shows that the combination of prestack inversion and AVO attribute analysis is an effective method of reservoir fluid prediction. |
