二维地震构造解译法在焦作煤田块村营的应用

Based on the 2D Seismic Application of Structure Interpretation in Kuaicunying of Jiaozuo Coalfield

构造分析是煤田煤炭开采、防水治水、安全经营的重要因素。二维地震可以有效解译构造的规模、产状及破碎情况。该文在综合分析块村营研究区地形地貌及地质条件的基础上,采用静校正、去噪、DMO迭加及时-深转换等多种技术手段,解译得出研究区组合断层七条,组合的七条断层中,落差大于200m的断层2条,落差100m～200m的断层3条,50m～100m的断层2条。

The structure analysis is the key of that Coal mining ,the waterproofing and regulates waterways, the safe management in coal field. The 2D seismic can interpret the scale of structure effectively, the occurrence and the stave situation. This article analysis the landform and the geological condi- tion,, positive use of the static correction, the de -noising, the DMO iterate and the time -depth conversion etc. , that the interpretation obtains general survey area seven combination faults, in the seven combination faults, the two faults dropping variance is bigger than 200m, the three faults 100m - 200m, the two faults 50m -100m.
