介绍了原油指纹色谱相关分析技术的原理。通过对一个区块的原油进行原始指纹分析,建立起原始"指纹"图版,并与混采原油中的色谱峰值进行对比,计算出不同层位的原油对单井的贡献,从而为油井生产措施的调整和方案的制订提供可靠依据,也可了解不同层位的原油动用程度,为下一步挖潜提供指导。同时,介绍了应用色谱法开发出的计算软件,给出了锦16区块锦2一丙5-215、锦2-6-307两口井在混层开采过程中主对油层组对单井产能实际贡献率的研究结果。

This paper presents the principle of the crude oil fingerprint-chromatogram correlation analysis technique. Firstly, establish the original" fingerprint" typical curve graph through analyzing the original fingerprint of the crude oil in a block, then, compares itwith the chromatogram peak of the commingled-produced oil, the contribution of oil in dif ferent layers to the well can be identified. This provides reliable basis for the adjustment of the production measures and the working out of the production plans of an oil well. With the help of it, the oil-produced degree of different layers can be known, which w1ll provide direction for the next production potential tapping. This paper also introduces the calculation software developed by using chromatography, presents the research results of the actual contribution of the main layers of wells Jin2-C5-2l5 and Jin2-6-307 in Jin-16 block to the single well productlvity during the commingled production.
