GC指纹分析可以区分不同层位原油的指纹特征，只要建立某个区块或井单层原油的标准指纹图版，就可采用最小二乘法计算原理测量合采井的产液剖面。研究了中原油田某断块10口沙二下、沙三上（玄上＋玄下）合采井（22井次）的产液剖面，并与生产测井进行了对比、从取样时间相近的两种方法测定结果来看基本吻合，有些特殊井结合动态分析进行了论证，证实用色谱指纹法测量该断块合采井产液剖面是有效的，具有不停产测量、快速、价廉等特点。
GC fingerprinting can distinguish the fingerprints of different layers of crude oil. As long as a standard fingerprinting plate of a block or well of single well is established, the production profile of the combined production well can be measured by the method of least squares calculation. The production profiles of 10 wells in the second block of the Central Plains oilfield, including Sha2 and Sha3 (Xuanzang + Xuanxia) were studied and compared with the production logging. From the point of similar sampling time The results of the two methods are basically in agreement with each other. Some special wells are combined with the dynamic analysis to prove that it is effective to use the chromatographic fingerprint method to measure the production fluid profile of the fault block. It has the characteristics of non-stop production measurement, fastness and low cost .
