油田水地化指标研究的新认识

本文根据南海莺歌海、琼东南、北部湾盆地以及珠三坳陷等4个地区的150个油田水样分析数据,综合研究其中一些地化参数,发现各参数之间存在着密切的联系.文中从理论和实践两个方面阐明了总矿化度与密度及电阻率的关系,重碳酸根、碳酸根与PH值的关系,水型与含油的关系,硫酸根与油藏之间关系的普遍规律,总结出一些经验计算公式,可以用数学计算方法求出各参数值.因此.减少了繁杂的测定过程,大大提高了工作效率.同时,通过研究各参数间的关系,能够更好地了解含油气构造的封闭程度及含油前景.

A NEW STUDIED RESULTS ABOUT GEOCHEMICAL PARAMETERS OF OIL FIELD WATER

In this paper some geochemical parameters of oilfield water were integrated studied. It is found that exists among parameters close relations. These relations include total dissolved solids and density, total dissolved solids and resistivity, bicarbonate carbonate and pH value, water type and oil-bearing content as well as sulfate and resenvoir. In the paper it is explained that universal law of among parameters by both theory and practice. Scientitic processing of a great many data results in some expenimental calculation formulas , which can work out theory value of various parameter by mathematical method. This decreases a lot of determine process and greatly improves efficiency of work. By study the relations among parameters, we can better understand the closed grade of pay stracture and oil-bearing prospect.
