荧光显微图像技术将荧光显微技术与图像的定量分析技术相结合,以储层中油水分布的显微特征为研究对象,从微观的角度直接观察岩石中烃类的不同成分、含量及油水在岩石中的赋存状态,量化分析样品中油、水含量,得到含油率、含水率、面孔率等量化指标,利用荧光图像显微参数识别油水层。大庆长垣以西地区油水关系复杂,各油层组储层物性及原油性质差别较大,流体性质识别难度较大。不同区块不同层位荧光显微图像特征差异较大,根据近几年的试油资料,利用定量处理参数结合图像特征,建成了齐家-古龙凹陷葡萄花、西部斜坡区萨尔图以及齐家凹陷高台子油水层识别方法。利用该项技术,在松辽盆地探井中浅层荧光显微图像分析及定量处理55口井851块样品,解释502层,试油37口井82层,可统计80层,符合71层,符合率达到88.8%。
Fluorescence microscopy combines fluorescence microscopy with quantitative analysis of images to investigate the microscopic characteristics of oil and water distribution in reservoirs, and directly observes the different components and contents of hydrocarbons in the rock from the microscopic point of view, Quantitative analysis of the oil and water content in the sample, quantitative indicators such as oil content, water content, and porosity were carried out in rocks, and the oil-water layer was identified by using the microscopic parameters of fluorescence images. The relationship between oil and water in the area to the west of Daqing Changyuan is very complicated. The physical properties of the reservoirs and the nature of the crude oil are quite different, making it difficult to identify the fluid properties. Fluorescence microscopic images of different layers have different characteristics in different blocks. According to the test oil data in recent years, with quantitative processing parameters and image features, the grape flowers in Qijia-Gulong Sag, Method of Identifying Oil and Water in Gaotaizi Oilfield of Sag. Using this technique, 851 samples of 85 wells were analyzed and quantified by shallow-layer fluorescence microscopy in the exploration wells of Songliao Basin. There were 82 layers of 502 wells and 37 wells of 80 wells, accounting for 80 layers and 71 layers, The rate reached 88.8%.
