摘　　要：地震正演模拟技术是用教学或物理的方法研究地震波在某种具体的简化模型中传播的特点,用来模拟真实地质结构条件下的地震波场。随着油气勘探的难度越来越大,该技术得到了越来越广泛的应用。以准噶尔盆地西北缘七区三维地震解释中的应用为例,正演模拟技术在地质模式的识别、断裂的精细刻画、速度异常的分析、小断裂的识别等方面都有较好的效果。Seismic forward modeling technique is used for simulation of seismic wave field in real geological structure conditions by means of mathematics or physical method through study of propagation characteristics of seismic wave in a simplifying model. In recent years, with the increasing in difficulty in oil and gas exploration, forward modeling technique has been used more and more widely. With seven areas in the northwestern margin of Junggar basin as an example, the application of forward modeling technique to seismic data interpretation is discussed. This technique has good results in geological pattern recognition, fine description of faults, analysis of abnormal velocity and small fault recognition.
