在油田开发中，随着开发中后期的到来，油井产量逐渐下降，含水率普遍升高，给油井的生
产管理带来较大难度。因此弄清油井的主力产层，对油田稳产增产措施和开发方案的调整具有重要作
用，本文在井壁取心储层沥青色谱指纹分析的基础上，建立数学模型，根据最小二乘法原理，确定各产层
与井口原油的相关关系，实现了对注水开发油井各油层产量的定量监测。以西北某油田2 口油井为例，
研究各产层的井壁取心储层沥青和混采井口原油色谱指纹相关关系，提出了有针对性的生产调整建议，
从实际的实施情况来看，效果明显。

In the middle -later stage of oilfield development, the well
yield drops gradually, and water cut goes up generally, which brings
some difficulties in producing and managing to well. Based on
fingerprint chromatograph analysis of reservoir bitumen of sidewall
coring, this paper establishes mathematics model. According to least
squares method (LSM) principle,it determines the correlationship of
each producing layer and well head crude oil and monitors
quantitatively each reservoir withdrawal for the well of water
flooding. And taking two oil wells of certain oilfield in northwest of
China for example, it researches on the correlationship between the
reservoir bitumen of each produced layer and mixed crude oil of the
well, and it has suggested the production adjustment suggestion of
specific aim. The effect is obvious from implementation. The
technology has applicability, less investment, period short, accurate,
fast characteristics and the applicable prospect.
