某构造油田水化学特征与油气藏保存条件研究

A Study of Water-Chemical Characteristics and Oil/Gas Preserving Conditions of a Certain Structure

通过研究我国东部某构造仅有的Ｑ－１井垂向上８个层位水化学特征，应用因子分析方法，得出该构造油气藏保存条件良好，并认为本区在渐新世末期曾经有过大的构造运动．通过研究认为，水化学特征的分析应与油气地质特征结合起来，这样，研究的结果才能反映真实的地质历史，才能回答现今油田水化学景观演变于今的客观规律．

he water-chemical characteristics of 8 vertical layers for Q-1 well in a certain farge structure of east China were studied by factor analysis method and conclusions were obtained that the preserving conditions of the oil/gas deposit is rather good and that a big tectonic movement took place in late Oligocene. It's very necessary that the analysis of water-chemical characteristics should be combined with the geologic features of oil and gas, thus the research results can reflect the true geologic history and can tell us the objective evolution laws of water-chemical landscape of oil and gas.
