| 摘 要： | 侏罗系沙河子组是松辽盆地北部主要聚煤层位。构造运动平稳的环境有利于形成厚度较大的煤层,煤层主要分布于东部断块起伏区,聚煤环境以河湖三角洲为主。利用地震资料可以确定煤层的反射特征及煤层的分布范围。

| Abstract: | The Shahezi Formation of Jurassic system the main coalg-athering position of the North Songliao Basin,The environment of stable tectonic movement is advantageotis to the generation of thicker coal seams.Coal seams are mainly distributed in the eastern block-rolling area.And coal-gathering environment is dominated by fluviolacustrine deltas.So the reflecting features and distribtition ranges of coal seams can be determined by means of seismic data. |
