摘要
总结了不同生物降解程度的稠油油源对比相应的研究方法;利用沥青质钌离子催化-氧化、沥青质中包裹烃等新方法对辽河断陷西部凹陷稠油油源进行了对比研究。最新研究发现,沥青质的结构特征使其可以包裹、键合油藏中的其他组分,而这些被包裹和键合的组分因受沥青质结构的有效保护,较少受到油藏后期改造的影响,具有原生性,因此近年来生物降解稠油的油源对比研究集中在沥青质的研究上。通过对高105等井的严重生物降解原油沥青质钌离子催化-氧化获得的一元、二元酸酯等产物进行GC/MS分析,获得许多有价值的新信息,在油源对比研究中发挥了重要作用。
This paper concludes the study methods of oil and source rock correlation for heavy oils with different degree of biodegradation;correlates the heavy oil and source rock in the western depression of Liaohe oilfield using the method of asphaltic ruthenium ion catalysis-oxidation and analysis of wrapped hydrogen in asphalt.The new study discovers that the structure of asphalt can wrap and bond other constituents in reservoirs,while these wrapped and bonded constituents had seldom been affected by later events due to the protection of asphalt structure and are kept primitive.Therefore,biodegradation heavy oil and source rock correlation in recent years has focused on asphalt study.A lot of valuable information has been obtained through GC/MS analysis of monoatomic and binary acid ester products obtained through asphaltic ruthenium ion catalysis-oxidation of serious biodegradation oil from wells like Gao105,and has played important role in oil-source correlation study.
