一种新的测量产液剖面的方法研究──有机地化色谱指纹法

A New Method of Measuring Fluid Production Profile

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。

The analysis of GC fingerprint can distinguish the fingerprint characteristics of the oil from different formation.If the standard fingerprint chart of the oil from a block or a well, the fluid production profile can be measured by least square method.The fluid production profiles of ten commingled producing wells in some fault-block in Zhongyuan Oilfield are studied by organic-geochemical chromatographic fingerprint method. The result of chromatographic fingerprint method is compared with that of production logging.When the sampling time is near, the results of two methods are identical on the whole.The results of some special wells are demonstrated by performance analysis.The method is effective to measure the fluid production profile,and has the characteristics of non-shut-in production measuring, quick speed and low price.
