摘要
对准噶尔盆地沙南油田的油源、油藏流体连通性、原油运移以及油气充注方向进行了研究。研究结果表明,沙南油田原油来源于二叠系平地泉组烃源岩;沙南油田二叠系梧桐沟组油藏流体的连通性较差,其中沙丘3井区、沙丘5井区和沙112井区三个井区油藏流体的连通性最差,它们各自独立成藏,分属不同油水系统;应用油气地球化学研究油藏流体的连通性结果与示踪剂研究结果相吻合。
we study oil source, fluid conductivity, oil migration and filling direction in Shanan oil fields, Junggar Basin. It indicates that the oil in Shanan comes from source rocks of that and Permian Pingdiquan Formation is of poor fluid connectivity . Especially three wells including well Shaqiu 3, Shaqiu 5 and Shaqiu 112 are featured by worst fluid connectivity. The three wells belong to different oil_water systems and form reservoirs individually. The paper demonstrates that fluid connectivity obtained from geochemical research coincides with the result from tracer research.
