在化学驱油产能实际生成过程中,通常是采取多个油层同时射开并进行混层开采的方式,将混层开采分为1,2,……,n个单开采层。通过应用色谱指纹技术可以清楚地判断出油层中的非均质性,利用单层原油色谱指纹的相似性以及不同油层色谱指纹的差异性,从而有效地趋避这种原油层的非均质性,进而达到很好的化学驱油产能效果。利用原油色谱指纹化合物参数,只需对井口进行取样,并在实验室仪器下进行分析和研究,便可实现对化学驱油产能的动态监测,且其检测效果得到明显提高。
In the actual formation of chemical flooding capacity, it is common to adopt a method in which multiple reservoirs are fired at the same time and subjected to mixed-bed mining, and the mixed-bed mining is divided into 1, 2,. Through the application of chromatographic fingerprinting technology, the heterogeneity in the oil layer can be clearly judged, the similarity of single-layer crude oil chromatographic fingerprints and the difference of fingerprints of different oil layers can be effectively utilized to avoid the heterogeneity of the crude oil layer, And then achieve a good effect of chemical flooding capacity. By using crude oil chromatographic fingerprinting compound parameters, the wellhead can be sampled and analyzed and researched under the laboratory equipment to realize the dynamic monitoring of chemical flooding production capacity, and the detection effect is obviously improved.
