摘　　要：在察哈素勘探区的三维地震数据体的解释中,通过对2-2上煤层河流冲刷无煤带相的认识和圈定,并根据河流冲刷无煤带相在空间上的分布特点,推测了聚煤期的冲刷河流水流方向,并进一步判定了区域内盆地沉积或沉积物源的补给方向;对照着依据三维数据体解释基础上的煤层厚度进行反演工作,分析、对比了河流冲刷无煤带相带的分布特点与同期煤层(2-2上煤层)富煤带(厚煤带)发育规律,归纳了一些认识和看法。In the explanation of 3d data volume in Chahasu exploration area, through recognition and circling 2-2上 coal seam river flow no coal area, based on its distribution feature in space, river flow direction in rich coal period was deduced, recharge direction of basin deposits or sediment was settled, the inversion work was conducted on thickness of coal seam based on 3d data volume, the distribution feature of river flow no coal area and 2-2上 coal seam rich coal area development law were compared, analyzed and summarized.
