摘要

大港探区上古生界煤系地层分布范围广、烃源岩发育和显微组分中富氢组分含量高。据计算,大港探区煤系地层二次成烃的天然气资源量为1994×10~8m~3;可见,煤成气勘探潜力大。介绍了大港探区上古生界煤系烃源岩的分布、显微组分特征、有机质丰度和有机质类型。认为:黄骅坳陷南区烃源岩保存最完整且具有持续深埋和二次成烃条件好等特点,该坳陷是寻找煤成气的有利区。

Abstract

Coal-bearing Formations in upper Paleozoic distributes extensively with large thickness, high organic matter abundance and high hydrogen content in maceral. Especially in southern area of Huanghua depression, the source rocks is completely preserved, and being continually subsided, with better condition of secondary hydrocarbon generation, so that it is the advantaged zone for exploring coal-related gas. The resource calculation indicates that natural gas resource volume is 1 994×108 m3 from secondary hydrogen.
