摘要 从油田开发动态地球化学监测的基本地质概念模型出发,应用油藏流体非均质性理论,分析了不同地质时期影响原油色谱指纹变化的地质因素。通过指纹GC/MS鉴定和实验模拟地下不同温度和不同时间的开采条件,分析了油藏开采过程中色谱指纹的变化规律。结果表明:原油色谱指纹稳定性主要和化合物的性质、含量以及色谱柱分离度有关。油藏开采过程中,适当碳数范围内的原油色谱指纹在井底和井口的不同温度条件下以及同一单层在一定的观测时间范围内具有稳定性。研究结果对进一步开拓原油色谱指纹在油田开发管理中的应用具有重要的理论价值。 Geological factors affecting petroleum chromatography compounds fingerprint are analyzed based on the process of the commingled production well and the heterogeneity of reservoir rocks and fluid distribution. The change of petroleum chromatography compounds is studied by modelling underground temperature and time interval in laboratory. Simulation results show that petroleum chromatography compounds fingerprint will be steady in underground and subsurface temperature. At the same time, they will be similar in different production period. The result will cough up a new thought in the quantitative simulation of reservoir performance.
