| 摘 要： | 常规地震反演预测储层效果往往不理想,为此提出了一套融合地质建模与地震反演技术提高储层预测精度的新方法,即采用地质建模技术精确建立初始波阻抗模型,再用该初始波阻抗模型约束进行地震反演,进一步提高地震反演储层预测精度。本文提出的新方法在涠洲11-1N油田进行了应用,储层预测精度得到了明显提高,解决了该油田生产中遇到的地质问题。

| Abstract: | Usually,the conventional seismic inversion can not result in satisfactory reservoir prediction,and a new method to improve reservoir prediction by merging geological modeling and seismic inversion is present,in which the geological modeling is used to build an accurate model of initial impedance,and then this model is used as the bound of seismic inversion,making the reservoir prediction by seismic inversion more accurate.An application of this new method in Weizhou 11-1N oilfield has indicated that the reservoir prediction is significantly improved,with the geological problems encountered in this oilfield been solved. |
