油藏地球化学测试技术在大庆油田的应用

The Application of the Test Technique on ReservoirGeochemistry in Daqing Oilfield

介绍了四项油藏地球化学新技术及在油田勘探开发研究中的实际应用效果。高温气相色谱技术把原油组分的分析范围从C1-C40提高到C1-C100含氮化合物分离测试技术,实现了对原油中微量含氮化合物的分离和色质绝对量定量检测;储层油水层划分技术开发出了判别油水层技术;原油开采动态监测气相色谱技术在国内首次开发出了四层原油产能配比实验方法。这些技术经过在大庆油田两年多的实际应用,在稠油类型、油源对比、油气运移、油水层划分、油井产能监测等研究中都发挥了重要作用。

It is introduced that the development process of four new techniques on reservoir geochemistry and applied result in the exploration and development. The analytical scope of components in crude oil is increased from C1-C40to C1-C100 by High Temperatures Gas Chromatography Technique. The separation and examination of phrrolic nitrogen compounds in petroleum is realized by the Separation and Test Technique of the nitride. It has already been completed to distinguish water-oil reservoir. Chromatogram fingerprint technique is firstly used in the calculation of allocation ratio of crude oil with four layers when oil well production. In past two years, many of actual application in Daqing oil-field show these techniques played the important role in the research of oil and source rock correlation, petroleum migration, water-oil reservoir distinction, and well deliverability monitor.
