【摘要】 冲积扇作为常见的油气储层,具有明显的地震响应特征。笔者采用频率—波数域的数值模拟方法,在冲积扇扇体发育的两个代表性方向上进行二维正演模拟,并使用正演数值模拟与偏移相结合的流程,得到了冲积扇在二维时间剖面上的地震响应特征,为验证冲积扇地质解释成果的准确性提供了有力检验手段。更多还原

【Abstract】 The alluvial fan is a common oil and gas reservoir with a significant seismic response characteristics.Using the frequency-wave number domain numerical simulation method,the authors performed a two-dimensional model simulation in two representative directions of the alluvial fan,and made use of the procedure of the combination of seismic forward simulation and the depth migration process to obtain the seismic response characteristics of the alluvial fan in two-dimensional time profile,thus providing a testing means for improving the correctness of the results of the alluvial fan geographic explanation.更多还原
