摘要
本文按物性测试和煤田勘探、开发资料,详细地讨论了煤系中砂体,灰岩及煤层的储集能力,认为它们是煤系中流体的储集层。井认为煤系上部杂色泥岩封闭能力较好。
Detailed discussion is made, based on results of physical tests and data concerning coalfield exploration and development, about the reservoiring capacities of sand masses, limestone and coal seams in the coal measures, layers which are believed to be capable of reservoiring fluids. It is also believed that vari-coloured mudstone in the upper part of the coal measures, being of good impermeability, act as impervious cover
