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.
Based on the data of 150 oilfields in four areas of Yinggehai, Qiongdongnan, Beibuwan Basin and Zhujiang Depression in the South China Sea, some of these geochemical parameters were comprehensively studied and found to be closely related to each other. The relationship between total salinity and density and resistivity is clarified from two aspects of theory and practice. The relationship between bicarbonate and carbonate and pH, the relationship between water type and oil content, the relationship between sulfate radical and oil reservoir General rules, summed up some empirical formula, you can use mathematical methods to calculate the value of each parameter.Therefore, to reduce the complexity of the measurement process, greatly improving the work efficiency.At the same time, by studying the relationship between the parameters can be better Understand the degree of closure of petroleum-bearing structures and oil prospects.
