摘要
黄骅坳陷埕海地区奥陶系天然气地球化学特征较为特殊,具有非烃含量高、稳定同位素重的特征。通过同位素特征,进一步结合地质、地化资料综合分析,对埕海地区奥陶系天然气的成因类型和气源进行探讨。认为埕海地区奥陶系天然气为煤成气,主力气源岩为石炭-二叠系烃源岩。
The geochemistry characteristics of Ordovician natural gas in Chenghai area of Huanghua depression have many special features,such as high content of non-hydrocarbon,heavy stable isotope characteristics.Based on the analysis of isotopic characteristics and further combined analysis of available data(geochemical and geological),for the discussion of gas source,its type and formation the gas from Ordovician formation of ChengHai area is considered as coal derived gas.The coal-derived gas is mainly generated from Carboniferous-Permian source rock.
