摘要
珠江口盆地勘探的不断深入,证实了珠江口盆地存在多构造、多含油层系、多原油物性的油气藏特征,这给常规录井在珠江口盆地复杂多样的原油特征尤其是轻质油层的油气显示发现与识别增加了难度。依托三维定量荧光技术检测范围广、灵敏度高、检测精度高、既能定性又能定量的技术优势,分析研究珠江口盆地恩平凹陷、惠州凹陷、开平凹陷等7个凹陷共50种原油样品的原油特征,总结出这7个凹陷的原油三维定量荧光波长分布规律,同时依据三维定量荧光技术的2个敏感参数(油性指数和对比级),建立了惠州凹陷和恩平凹陷的三维定量荧光解释评价图板和标准。应用分析结果表明,其评价结论与实际测试结果吻合率高,应用效果好。
The continuous exploration in Pearl River Mouth Basin confirms the hydrocarbon reservoir characteristics of multistructure,multi-oil-bearing series and multi-crude oil physical properties in Pearl River Mouth Basin.This makes it difficult for conventional mud logging to discover and identify the complex and diverse crude oil characteristics,especially show of gas and oil of light oil layers in Pearl River Mouth Basin.Based on the advantages of three-dimensional quantitative fluorescence technique,which has wide detection range,high sensitivity,high detection accuracy,both qualitative and quantitative,the crude oil characteristics of 50 crude oil samples from 7 sags,such as Enping sag,Huizhou sag and Kaiping sag in Pearl River Mouth Basin were analyzed and studied.Three-dimensional quantitative fluorescence wavelength distribution of crude oil in 7 sags was summarized.At the same time,based on two sensitive parameters(oiliness index and contrast level)of three-dimensional quantitative fluorescence technique,the three-dimensional quantitative fluorescence interpretation and evaluation chart and criteria of Huizhou and Enping sags were established.The results of application analysis show that the evaluation results are in good agreement with the actual test results and the application effect is good.
