地震勘探技术在准东三井田定量解释中的应用

Application of Seismic Exploration Technology in Quantitative Interpretation of No.3 Coal Well in Zhundong Area

摘要:

通过二维、三维地震勘探结合地震正演数值模拟及波阻抗反演结果来预测新疆准东煤田大井矿区三井田B1煤层结构，定量解释了B1煤层一次分叉合并区范围，并准确预测了一次分叉合并区0.8~2m厚的夹矸的范围。经过钻孔验证，该方法精度高，为矿井开采及巷道布设提供了准确的地震地质资料。

Abstract:

Through second and third seismic exploration method, combining with the forword numerical simulation and wave impedance inverson, structures of B1 coal strata in No.3 coal well in Dajing coal mine of Zhundong coal field in Xinjiang have been predicated, bifurcation and combination scope of B1 coal strata has been primarily explained quantitatively, and the range of 0.8~2.0m thickness of gangue in B1 coal strata has been accurately forecasted. After drilling verification, it is regarded that this method is feasible with high precision. It will provide accurate seismical geologica data for coal mine.
