西部高原咸化地表静校正方法应用
|
摘要
中国西部高原咸化地表和地下结构复杂多变,静校正问题突出。通过多年探索,逐步形成了针对高原咸化地表的静校正技术系列:复杂地表的初始模型构建技术;极低信噪比的标准层静校正技术;高陡构造的综合静校正技术;盐碱地表的炮、检域叠加迭代静校正技术;流动大沙漠的原生地表初至静校正技术。这一系列静校正技术有效地解决了西部高原咸化地表条件下的静校正问题,对于提高咸化地表地震资料的信噪比和成像质量发挥了积极作用。
The surface and underground structure of the plateau are complex and changeable,and the static correction problem is distinct. Through years of exploration,the authors gradually formed a series of static correction technologies for plateau salty surface construction: the initial model of complex surface; extremely low SNR standard layer static correction technology; high steep structure comprehensive static correction technology; static correction,surface gun domain iterative detection of saline desert flow; the original surface refraction static correction technology. This series of static correction technologies can effectively solve the problem of static correction in the Western Plateau under the condition of saline land surface. It has played an active role in improving the signal-to-noise ratio and the image quality of the surface seismic data.
