彬长矿区小庄矿井侏罗系延安组煤层属于巨厚煤层,在全区广泛分布。井田内古隆起发育,地层厚度、产状、煤层厚度及起伏形态受古地形控制,古隆起区附近煤层变薄、缺失,煤厚解释难度较大,凹陷区煤层厚度相对较厚,分布较稳定。通过地震正演模拟研究煤层厚度变化所引起的煤层波组特征变化的规律,结合钻孔资料,总结区内煤层厚度变化与其赋存深度的相关关系,采用煤层赋存规律和煤层反射波波组特征相结合的方法,解释了区内煤厚变化趋势,结果与地质规律相吻合。
The coal seam of Yanzhuang Formation of Juzhuang in Xiaochuang Mine in Binchang Mine Area belongs to the thick and thick seam, which is widely distributed in the whole area. The paleo-uplift develops in the minefield. The thickness of strata, occurrence, seam thickness and undulation are controlled by the paleo-topography. The coal seams near the paleo-uplift area are thinned and missing, and the coal thickness is difficult to explain. The thickness of the coal seams is relatively thick and the distribution is relatively stable . Based on the data of borehole and the correlation between the variation of coal seam thickness and the depth of its occurrence in the area, the law of occurrence of coal seam and the group of reflected wave of coal seam Characteristics of the combination of methods to explain the trend of coal thickness changes in the region, the results coincide with the geological laws.
