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。
Oilfield water is an integral part of any oil and gas reservoir system and coexists with hydrocarbons in underground rock pores in a variety of forms. The shape and salinity of oilfield water and its movement have always been closely related to the formation, migration and accumulation of oil and gas and the formation, preservation and destruction of oil and gas reservoirs. Whether in the distribution of total salinity or in the distribution of chloride ions, it is known that there is a very good correspondence between the hydrocarbon accumulation area and the abnormally high value areas, especially the chloride ion distribution as a response index indicating the hydrocarbon accumulation area with a higher resolution . Therefore, the research on the characteristics of the hydration field in oilfield is of great significance to oil and gas exploration and development.
