摘要: 研究油田水中的微量金属元素及其分布规律,对判断油气的形成、运移和聚集,指导石油普查勘探具有重要意义.本文通过对泌阳凹陷194个油田水样品的系统分析,研究微量元素与沉积环境及水文地球化学相带的关系,对进行油源对比,追索石油运移的方向,推断油气的聚集、分布,将提供一些有益的信息.Abstract: Through the systematic analyses of 194 water samples from the oil fields in Biyang Depression,the relationships of the trace elements to the depositional environments,and hydro-geochemical zonation are studied.Then,the oil and source rocks are correlated in order to trace out the direction of oil and gas migration.Thereafter,the accumulation and distribution of oil/gas are inferred that it would undoubtedly provide some helpful informations for petroleum exploration.
