煤田地震勘探技术的不断发展,数据采集逐步进入地表复杂地区,由于地表条件复杂,处理静校正量变化大,如果处理模块和参数选择不当,将导致地震剖面信噪比和分辨率降低,严重影响资料解释的精度。本文以准格尔煤田唐家会井田为例,论证和分析了该区地表复杂条件下三维地震资料二次处理采用的方法、手段和措施,最终得到高信噪比、高分辨率地震剖面,大大提高了地震资料解释精度,满足了井田开采的需要。
The continuous development of coalfield seismic exploration technology, data acquisition gradually into the complex surface area, due to the complex surface conditions, processing static correction large changes, if the processing module and the parameters are not properly selected, will lead to seismic profile SNR and resolution decreased, seriously affected Data interpretation accuracy. Taking Tangjiahui Minefield in Zhunge’er Coalfield as an example, this paper proves and analyzes the methods, measures and measures adopted by the secondary processing of 3D seismic data under the complex surface conditions in the area, and finally obtains the high S / N ratio and high resolution seismic section, Seismic data interpretation accuracy, to meet the needs of minefield.
