摘要
本文在讨论吐鲁番坳陷油田水无机化学及有机地球化学基本特点的基础上，分析了不同含油气区油田水的有机质含量、低碳脂肪酸分布、芳烃含量及紫外吸收光谱、荧光光谱的主要特征。对该坳陷的油气藏按保存条件的优劣迸行分类，讨论了不同类型油气藏油田水化学特征，重点分析了ｒＮａ／ｒＣａ──ｒＮａ／ｒＣ１相关分析图上的聚类特点。据此阐述该坳陷油田水地球化学基本特征及其石油地质意义。
This paper gives a discussion on the organic chemical and organic geochemical characteristics. Oil and gas reservoirs in this area are classified based on the above analyses and intergrated by analyses of main characteristics of the organic content, distribution of low carbon fatty acids, ultralviolet absorption spectrum, arromatic content and fluorence spectrum in the oil field, according to the conservation conditions. This paper also discusses the inorganic chemical characteristics of the oil field waters in non-deteriorated oil reservoir, slightlydeteriorated reservoirs, non-unofrmly deteriorated reservoirs, surface seapaged reservoirs and structurally strongly deteriorated reservoirs. Moreover cluster analysis features in the correlation of rNa/rCa─rNa/rC1 in oil filed water in reservoirs with various conservation conditions is stressed. Thus, the basic geochemical characteristics and its petroleum geological significance of oil field waters occured in this depression is demonstrated preliminarily in this paper.
