摘　　要：以三维地质模型为基础,通过拟合地震数据对模型进行了修正方法的研究和应用。应用模型-地震-模型闭合循环的流程,建立了地质模型返回地震并更新模型的新流程。以实际模型为基础,分析地震敏感参数,通过人机交互的方法修改了三维地质模型的属性数据,使得模型正演地震数据与观测地震数据更加接近,模型更加逼近开发阶段的井震数据并且符合地质规律。Based on the 3D geological model,this paper studies a new method of modifying the model by using seismic forward.A new flow of returning geological model to seismic and updating the model is established.Based on the actual model,the seismic sensitive parameters are analyzed and the attribute data of the 3D geological model is modified by human computer interaction method.As a result,the forward seismic data of the model is closer to the observed seismic data and the model is closer to the well and seismic data,which consists with the geological law in the development stage.
