| 摘 要： | 二连盆地内的凹陷窄而狭长,断裂发育,构造变化剧烈,速度横向变化快,常规作图方法难以满足精细构造解释的要求.采用叠前时间偏移后的叠加速度谱生成速度模型,并用井震标定速度进行校正,形成高精度的变速三维速度场,用它对地震层位作时深转换,较大地提高了构造成图的精度. |
| 关 键 词： | 3D地震变速场 时深转换 构造成图 叠前时间偏移 二连盆地 |

| Abstract: | Depressions in Erlian Basin are long and narrow with complex faults and structures.Challenges for correct structure mapping include complex structure imaging and sharply lateral variable velocity analysis.Traditional methods by using stack velocity spectrum do not meet the demands of high precision seismic interpretations.The improved structure mapping in this paper involves the following steps:(1) creating velocity model by stacking velocity spectrum based on seismic pre-stack time migration data;(2) calib... |
