二氧化碳吞吐开采稠油影响因素实验研究

Laboratory study on influencing factors of CO_2 huff and puff in heavy oil reservoir

  • 摘要: 在实验室内使用化学药剂进行反应,就地生成二氧化碳,利用国内某油田的稠油样品开展了连续二氧化碳吞吐+水驱油、二氧化碳吞吐+水驱交替实验,并对不同原油黏度、不同物性及不同含油饱和度的岩心进行了驱油效率的对比分析。实验结果表明,原油黏度较小、物性较差、含油饱和度较高的岩心驱油效果较好。

     

    Abstract: Chemical agents have been used in laboratory to generate in-situ carbon dioxide.By using heavy oil samples of some oilfield,an alternate experiment between continuous co2 stimulation + water flooding and co2 stimulation alternate+ water flooding has been carried out,and the comparative analysis of oil displacement efficiency on different crude oil viscosity,physical property and oil saturation of cores has also been carried.The laboratory results indicate the viscosity of crude oil is smaller,physical properties are poor,and the cores with high oil saturation has better flooding effect.
