摘要：

油藏流体动态色谱指纹监测技术的基本依据在于同油层中的原油具有相似色谱指纹、不同油层的原油色谱指纹的差异性以及指纹化合物的可配比性。其分析结果是油田调整挖潜,制定提高采收率措施的重要依据。应用建立的色谱指纹动态监测的数学模型,对东部某油田X37-0开发井区,NmⅢ⁷和NgⅡ³混采的西37-1井和西38-1井计算出NgⅡ³层的贡献分别为88.98%和86.09%,NmⅢ⁷层的贡献率分别为11.02%和13.91%。并在相同实验条件下按NmⅢ⁷:NgⅡ³为85:15的比例配比成混合样品"配16",提取与实测样品相同的配对指纹参数进行相关分析与检验,佐证了模拟计算结果的正确性。

Abstract:

The theoretical bases for dynamic monitoring of chromatographic fingerprint of reservoir fluids include:1) crude samples from the same oil layer have similar chromatographic fingerprints;2) crude samples from different oil layers have different chromatographic fingerprints;3) fingerprint compounds can be partitioned.The results of above-mentioned dynamic monitoring are key basis for adjustment of development plan and selection of EOR measures.A mathematical model for dynamic monitoring of chromatographic fingerprint was set up and applied to the X37-0 wellblock in an eastern oil field.The following calculation results are obtained.Pay zone NgⅡ³ contributes 88.98% and 86.09% to the total production of well Xi37-1 and well Xi38-1(both are in commingled production of NmⅢ³ and NgⅡ³) respectively,while NmⅢ³ contributes 11.02% and 13.91% respectively.Under the same experimental conditions,a "Mix 16" sample is prepared with samples from NmⅢ³ and NgⅡ³ according to a proportion of 85:15.Fingerprint parameters from Mix 16,the same as those from the measured samples,are recorded,analyzed and tested.It is proved that the model calculations are correct.
