摘要
我国川东北地区油气资源丰富,储层裂缝发育,构造复杂,是典型的复杂地表、复杂构造地区。在开展采集 设计时,首先从正演着手,分析各向异性存在条件下的地震波运动学及动力学特征;然后对实际地震资料进行处 理分析,在此基础上完成工前试验,即基于采集、处理、解释一体化的三维地震采集设计;提出了针对靶区各向异 性及复杂构造的高精度、宽方位、长排列的三维地震技术。
The northeast part of Sichuan province is rich in hydrocarbon resources. However, it is a typical area of ragged topography and complex structures. 3-D seismic acquisition design for such an area poses a great challenge. Starting from forward modeling, the author analyzed the kinematic and dynamic behaviors of seismic wave in anisotropic media, and performed data processing on the real data. Based on the results, field tests were implemented and the target-oriented design was finalized.
