在任何―个油气藏系统中油田水都是一个不可缺少的组成部分并以各种不同的形式与油气共存于地下岩石孔隙中。油田水的形咸及其运动规律与油气的生成、运移、聚集以及油气藏的形成、保存、破坏始终有着极其密切的关系。不论是在总矿化度分布还是在氯离子分布方面,已知油气聚集区与异常高值区有非常好的对应关系,特别是氯离子分布作为指示油气聚集区的响应指标,分辨率更高。因此,油田水化学场特征的研究对于油气勘探和开发有着十分重要的意义。

Oil field water is coexist with oil and gas in tin-subsurface mineral porosity, and it is an absolutely necessarily composition in each of the reservoir systems. All the time its forming and laws of movement has a close relationship with petroleum generation, migration, acxu mulation and pool forming, preservation, even destruction. Whether distribution of total salinity or Cl ion. there is a good corresponding telween petroleum accumu lalion section and abnormal high values, in particular, as a response pointer indicates petroleum accumulation sec tion. distribution of Cl- ion has a higher resolation Therefore, the study of hydrochemistry field plays a very significant role in petroleum exploration and development.
