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。
Increasing the accuracy of using rock pyrolysis data to evaluate the properties of reservoirs and crude oil is of great significance for the timely discovery of oil and gas in the field, determination of the industrial value of reservoirs and selection of reasonable oil-bearing formations. Based on the statistical analysis of a large number of reservoir rock pyrolysis data and oil test results, the concept of “bright spot index” of geochemistry was put forward. The evaluation of crude oil properties, oil saturation calculation, Division and other aspects of the application. The results show that the discriminant effect of crude oil is obviously better than that of the commonly used oil yield index in discriminating the nature of crude oil. In the calculation of oil saturation, it has the advantages of small dependency on other data and the method is more direct. In terms of layering, statistical methods are simpler than conventional methods and are especially suitable for rapid evaluation while drilling.
