民东地区埋藏浅,物性好,具备效益勘探潜力,随着勘探深入,油气富集及分布规律成为该区勘探发展的瓶颈问题。本文通过分析原油生物标志物特征,研究了民东-长春岭地区扶余油层的油源,应用地球化学参数在油气运移过程中的变化,结合油气疏导体系,分析了民东-长春岭地区油气运移的方向和主要路径,最终分析该区成藏特点,并预测出成藏有利区。
The eastern part of the area is shallow buried with good physical properties and potential exploration potential. With the deepening of exploration, oil and gas enrichment and distribution have become bottlenecks in exploration and development in this area. In this paper, we analyzed the characteristics of crude oil biomarkers, researched the oil source of Fuyu oil field in the Widong-Changchunling area, applied the changes of geochemical parameters in the process of oil and gas migration, combined with the oil and gas drainage system, analyzed the oil and gas Migration direction and the main path, the final analysis of the characteristics of the area of accumulation, and predict the favorable area for hydrocarbon accumulation.
