油藏地球化学的形成和发展丰富和扩大了油／源（油）对比技术和概念。本文综合常规对比和分子对比的地球化学油／油对比技术，分析了辽河油田千１２区块油藏之间的相关关系，探讨了油藏的注入史，指出千１２区块莲花油藏、兴隆台油藏与馆陶油藏的甾萜类和多环芳香烃宏观组成特征相似，它们可能来自相同的主力油源层。但馆陶组原油与兴隆台组原油的成熟度比莲花组高，表明它们的运移途径比莲花油藏远，注入时间亦比莲花组晚，且兴隆台组原油遭受了激烈的降解作用。因此，对兴隆台油藏的开发评价应当考虑到油藏发育历史的特殊性。应用油藏地球化学的油／油对比技术研究不同油层之间油／油关系，加强对其油藏形成机理及时空分布规律的认识，对加强该区块油藏的开发将具有积极的指导意义。
The formation and development of reservoir geochemistry enrich and expand the oil / source (oil) contrast technologies and concepts. Based on the geochemical oil / oil contrasting technique of routine comparison and molecular comparison, this paper analyzes the correlation between Qian12 block reservoir in Liaohe Oilfield, explores the history of reservoir injection, points out that Qian12 block lotus reservoir is booming The macroscopic compositions of the terpenoids and polycyclic aromatic hydrocarbons in the reservoirs of the Tarim Basin are similar to those of the reservoirs, which may come from the same main oil source. However, the maturity of Guantao crude oil and Xinglongtai crude oil is higher than that of Lianhua oilfield, indicating that they migrate far away from the lotus reservoir and the injection time is later than that of Lianhua oil group. The crude oil of Xinglongtai oil group suffered intense degradation. Therefore, the development evaluation of Xinglongtai reservoir should take into account the particularity of reservoir development history. Applying the oil / oil contrast technology of reservoir geochemistry to study the relationship between oil / oil in different oil layers, and strengthening understanding of its reservoir formation mechanism and temporal and spatial distribution rules will have a positive guiding significance for enhancing the development of this block reservoir .
