| 摘 要： | 综合利用钻井、岩心及地震等资料,结合沉积学及层序地层学相关方法和理论,对琼东南盆地崖城组聚煤环境特征及成煤作用展开研究。琼东南盆地崖城组煤层主要见于潮坪潮上带和潮间带的泥炭坪、辫状河三角洲平原泥炭沼泽及扇三角洲平原泥炭沼泽。以聚煤环境为主线,考虑到古构造的影响,总结出琼东南盆地的聚煤模式：潮上带及潮间带面积最大,为主要的聚煤环境;缓坡带成煤沉积体系的分布广于断控陡坡带;崖二段具有较强的聚煤潜力。

| Abstract: | Based on the drilling data,core data and seismic information,this paper discusses about features of coal-accumulating environment and coal-forming of Yacheng formation in Qiongdongnan basin with application of methods and theories of sequence stratigraphy and sedimentology.Coal seams of the Yacheng formation are mainly found in peat flat of supralittoral zone and intertidal zone of tidal flat,peat swamps of the braided river delta plain and fan-delta plain.Focusing on the coal-accumulating environment and c... |
