灰岩低信噪比地区地震资料处理难度大,如何有效提高地震资料信噪比、解决因激发条件引起的一致性问题显得至关重要。正确使用各种处理方法与技术可以有效提高地震剖面信噪比,获得高质量目的层波组,为查明有利目标区及优化页岩气勘探部署方案提供了资料基础保障。
It is very difficult to process the seismic data in the low signal-to-noise ratio area of limestone. How to effectively improve the signal-noise ratio of the seismic data and solve the consistency problem caused by the excitation conditions is very important. Correct use of various processing methods and techniques can effectively improve the signal-to-noise ratio of seismic sections and obtain high-quality target-layer wave sets, which provides a data foundation for identifying favorable target areas and optimizing shale gas exploration and deployment plans.
