| 摘 要： | 陆相成煤环境及断陷构造特点,致使二连盆地内煤层具有层数多、间距小、厚度横向变化大、标志层少等特点,利用钻探资料进行煤层对比难度大,其结果将直接影响对煤层、煤质评价及煤炭资源量估算。考虑到研究区煤层赋存特点,利用三维地震成果,对该区进行了煤层辅助对比,其结果与原有7个钻孔煤层对比成果存在差异。通过三维地震层位对比与构造解释方案的核查,结合波阻抗反演结果和测井资料重新解释,认为三维地震的煤层对比是合理的。该实例表明,综合利用测井资料、三维地震解释和波阻抗反演等,可有效提高煤层对比的可靠性,提高煤炭资源地质勘探阶段的控制精度。

| Abstract: | Coal seams in the Erenhot Basin have characteristics of multiple coal seams with smaller intervals,large transversal variations and lack of marker beds caused by limnic coal-forming environment and fault depression structure.It is difficult to carry out coal seams correlation only relying on drilling data,and results can directly impact coal seam,coal quality assessment and coal resource estimation.In view of coal hosting characteristics in the study area,the 3D seismic results are used in additive coal sea... |
