摘要(Abstract)：

本文概述了含油砂岩水中微量水的萃取水体积测定及水中氯离子分析方法,同时根据两口井密闭取心不同层位、不同水洗程度岩心中含油、含水饱和度及水中氯离子含量分析资料,探讨了储层含油砂岩水中氯离子含量与含油、含水饱和度的关系与变化特征。 本文认为,由于注入水的长期冲刷,必然造成储层岩心中氯离子含量下降,在已知区块注之入水中氯离子含量变化范围情况下,将不同层位岩心含油、含水池和度与水中氯离子含量变化进行对比,即能明显地判别不同开采期储层水洗程度。
In the paper, the methods for the extraction and measurement of trace water from oil-bearing sandstones, and the analysis of chloride ions in the water are described, furthermore, based on the analysis data on oil and water saturations and the content of chloride ions from two closed cored wells at different intervals and with different water swept status, the relationship between chloride ions content in the formation water within oil-bearing sandstones and oil, water saturations as well as the variation characteristics are discussed, In the paper, the authors suggest that because of the long period of flushing by the injected water, the chloride ion content in the water within reservojr rocks must be reduced. Within a certain range of change in chloride ion content in the injected water, with the correlation between oil and water saturations and the variation of the chloride ion content in the formation water within the cores taken from different intervals, the reservoir swept status at different production stages can be clearly understood,
