构造模型正演技术在下扬子区初步应用效果

针对圈闭评价中构造形态的可信度这一问题,笔者选用有限元地震波模拟正演技术,对下扬子区的HQ、DY、BP等典型构造进行模型正演计算。结果表明,它有效地克服了解释过程中的片面性,为落实构造、评价圈闭提供了依据。

THE EFFECT OF APPLYING FORWORD MODELING TECHNIQUE FOR STRUCTURE MODELS IN LOWER YANGTZE AREA

Aimed at solving the problem of the creditability of structure shape in trap evaluation, the authors have advanced the forward modeling for calculating such typical structure models as HQ, DY and BP in Lower Yangtze area by using the finite-element forward modeling technique of seismic wave. The result shows that this technique provides basis for structure determination and trap evaluation and eliminates one-sideness in the interpretation process.
