摘要
碳氧比测井目前是淡水油田油井下钢套管后判断地层油水状况的唯一方法。新开发的仪器确定含油饱和度的精度可提高到10%以内,并可在油管中进行测量获取井眼油水分布资料。这些新开发的仪器主要采用新型的高密度、高原子序数的闪烁晶体BGO和GSO。阐述了BGO、GSO的特点、性能,列举了测井实例。
At present, the C/O logging is the only way for the fresh-water oilfields to judge the stratigraphic oilwater status after downing the steel casings. The new-developed device can give an accuracy of oil saturation within 10 per cent, and make mea(?)urements in the oil-tubing so as to get oil-water distribution data. It uses the new-type scintillation crystals——BGO and GSO with high density and high atomic numbers. The performance of such crystals are introduced, and some field examples are given too.
