| 摘 要： | 中国页岩油勘探进入了全新的勘探领域，页岩油储层比常规储层复杂得多，如何提高页岩油储层的成像精度是页岩油地震勘探的关键环节.宽方位三维地震技术是目前普遍采用的地震勘探技术，因为宽方位地震在提供高品质地震资料的同时还能够解决相对较难的地质问题.以松辽盆地齐家古龙凹陷Y88研究区为例，利用宽方位资料进行针对页岩油储层处理，分析了宽方位资料的波场特征、信噪比及频率等特征，在此基础上确定了宽方位资料的处理流程，并采用了宽方位、宽频带的高分辨率保幅特色处理技术进行处理，取得较好的成像结果.

| Abstract: | Shale oil exploration in China has entered a new field. As shale oil reservoir is much more complex than conventional reservoir, the improvement of imaging accuracy of shale oil reservoir is the key to shale oil seismic exploration. The wide-azimuth 3D seismic technique is widely used in seismic exploration currently as it can solve relatively difficult geological problems while providing high-quality seismic data. Taking the study area Y88 in Qijia-Gulong depression of Songliao Basin as an example, the paper conducts shale oil reservoir processing by wide-azimuth data, and analyzes the characteristics of wave field, signal-to-noise ratio and frequency. On this basis, the processing flow of wide-azimuth data is determined and the wide-azimuth and broadband high-resolution amplitude-preserving processing technique is adopted for better imaging. |
