| 摘 要： | 通过对中国西部吐鲁番盆地北部山前带的宽、窄方位角地震数据进行对比分析研究表明:不同窄方位观测时,由于观测方向与断裂走向斜交存在较为严重的构造假象,并造成小断层难以成像.对于断裂带而言,不同方向窄方位角观测成像阴影带不同.全(宽)方位角观测可以获得各个方向小断层比较好的成像,同时也可以有效地获得断裂带的空间范围.在此基础上,通过随观测方位角不同的地震属性的变化来寻找和研究裂缝性储层发育区和估计裂缝发育的主要方向. |

| Abstract: | The comparison analysis of narrow and wide azimuth seismic data in mountain front areas of Turpan Basin, western China, shows that the observation direction bevelling the direction of faults or fault zones will cause the imaging loss of small faults, and the little fault will be poorly imaged in seismic data. In fault belts, the imaging shadow zones change with the variety of narrow azimuth observation directions. All (Wide) azimuth data can obtain better imaging of little faults in all directions, and can get the space extension of these fault belts. So, we can further study the most fractured reservoir extensions and predict the main direction of fractures through analyzing the change of seismic attributes in different narrow azimuths. |
