摘要: 提高利用岩石热解资料评价储层及原油性质的精度,对于现场及时发现油气显示,确定储层的工业价值,选择合理的试油层位具有重要意义.在大量储层岩石热解资料、试油成果统计分析的基础上,提出了地化“亮点指数”的概念,并探讨了“亮点指数”在塔里木盆地原油物性评价、含油饱和度计算、油水层划分等方面的应用.研究结果表明,在原油性质判别方面,其判别效果明显优于常用的油产率指数方法;在计算含油饱和度方面,具有对其他方面的资料依赖性小的优点,方法更趋直接;在油水层划分方面,比常规参数统计方法更加简单,特别适合于随钻快速评价.

Abstract: To improve the evaluation effect of reservoir and crude oil properties by using geo-chemical logging data is very important for recognizing oil-bearing reservoirs,determining their commercial value and selecting the test formations.On a basis of a large number of statistics and analyses,a new parameter named "Bright Spot Index"(BSI) was introduced in this paper.A wide application was studied including oil property classification,oil saturation calculation and oil-bearing layer recognition in Tarim Basin.The results show that BSI is not only more efficient than other common parameter,like oil production index(OPI) for determining the crude oil properties,but also it can be used for calculating oil saturation more directly.By using BSI,to recognize the commercial value of reservoir becomes simpler and more efficient and it is especially suitable for rapid reservoir evaluation on well site.
