准格尔煤田地表复杂区三维地震资料二次处理及其效果
|
摘要
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 step by step into the complex surface area,Due to the complicated surface conditions,dealing with change of statics,If processing module and parameter improper selection,will lead to reduced signal-to-noise ratio and resolution of seismic profiles,serious impact on the accuracy of data interpretation.Based on the ZhunGeEr coalfield TangJiaHui mine as an example,Argumentation and analysis of the complex surface in the region under the condition of secondary 3-d seismic data processing methods,means and measures,End up with high signal-to-noise ratio,high resolution seismic section,Greatly improved the precision of seismic data interpretation,Meet the needs of the mine exploitation.
