准噶尔盆地含油气岩芯成藏研究基本思路

含油气岩芯蕴含有油气生成、运移、聚集、成藏的丰富信息，对于这些信息，以准噶尔盆地陆西地区为例，根据地质与有机和无机地球化学相结合的方法，提出了成藏研究的基本思路和流程。认为研究中应首先分析含油气岩芯在油气显示段的代表性，在此基础上，主要分5步开展工作：判识油气源、恢复油气运聚过程、识别油气水层、研究油气运聚类型、建议有利成藏领域与勘探方向。这一基本研究思路可供同类工作参考借鉴。基于陆西地区提出的一些新指标参数和认识结论可应用于区域勘探生产和基础研究。

BASIC THOUGHT FOR INVESTIGATING PETROLEUM ACCUMULATION BASED ON CORE WITH HYDROCARBON SHOWS：A CASE STUDY IN THE JUNGGAR BASIN

Core with hydrocarbon show comprises much information of petroleum generation,migration,accumulation and formation.In this paper,basic thought for investigating such information is suggested based on a case study in the Luxi area of the Junggar Basin.The method is to integrate geological and (organic and inorganic) geochemical methods.It is proposed that the representiveness of the core with hydrocarbon show in the bulk hydrocarbon-show section be determined at the first,then,five steps is adopted,including determining hydrocarbon source,reconstructing petroleum migration and accumulation process,identifying oil-gas-water interval,analyzing petroleum migration and accumulation and predicting favorable petroleum forming area and exploration strategy.In general,the above fundamentals provide reference for similar studies.Additionally,practical research results in the Luxi area imply prospective on regional exploration and studies.
