为了解决石油勘探开发中所面临的早期评价问题,应用热解气相色谱法,利用热解装置、气相色谱仪、数据处理工作站组成的热解气相色谱仪对储集岩进行分析,得到热蒸发烃、热解烃色谱曲线及其各种化合物、系列化合物分析数据。该技术对不同储集岩进行分析对比获得如下结论:①利用热蒸发烃正烷烃碳数分布及含烃量有助于区分水洗油层、细菌降解油层、非生产层、凝析油层;②在对储集岩热解烃分析中发现油沙岩与生油岩干酪根的热解烃图形是不同的,通过研究不同类型油砂岩热解烃色谱曲线可更好地了解不同类型油砂岩在重质组分中的烃类分布。因此,在生产中该技术可为勘探开发提供合理的勘探数据,准确评价储集岩性质,对现场快速、准确评价储层具有重要意义。
In order to solve the problem of early evaluation in petroleum exploration and development, pyrolysis gas chromatograph was used to analyze the reservoir rock by using pyrolysis gas chromatograph consisting of pyrolysis device, gas chromatograph and data processing workstation to obtain thermal evaporation hydrocarbon , Pyrolysis hydrocarbon chromatogram and its various compounds, series of compound analysis data. The technology of different reservoir rock analysis and comparison obtained the following conclusions: ① The use of thermal evaporation of hydrocarbon n-alkane carbon number distribution and hydrocarbon content help distinguish between wash oil, bacteria degradation, non-production layer, condensate reservoir; The pyrolysis hydrocarbon patterns of oil sandstone and kerogen kerogen were found to be different in pyrolysis hydrocarbon analysis of reservoir rocks. By studying the pyrolysis hydrocarbon chromatograms of different types of oil sandstone, the pyrolysis hydrocarbon profiles of different types of oil sandstone can be better understood. Hydrocarbon distribution in components. Therefore, this technology can provide reasonable exploration data for exploration and development, and accurately evaluate the nature of reservoir rocks in production, which is of great significance to the rapid and accurate evaluation of reservoirs on site.
