摘要
对于苏北盆地盐城凹陷朱家墩气田的气源存在多种不同看法,但均无气/源对比的直接证据加以证明。作者借助天然气轻烃指纹气相色谱分析方法以及岩石轻烃指纹气相色谱分析方法进行直接的气/源对比,研究结果证实朱家墩气田的天然气为混源气,以海相油型裂解型干气为主,渗混了海、陆相混源型油型高熟气。
It is undoubted that the discovery of the Zhujiadun gas field brings the exploration of marine gas a bright future in the Yangzi district. There are kinds of different viewpoints in the previous researches, but they all can not be proved by an evidence of direct gas-source correlation. With the aid of the gas chromatograph method of gas light hydrocarbon fingerprints and rock light hydrocarbon fingerprints, the paper confirms that the gas in Zhujiadun is a kind of admixture and mainly marine oil cracked dry gas intermingling with oil-high mature gases from continental and marine admixtures.
