摘要

摘要: 塔河油田志留系发育3种油气藏类型，分别为地层油气藏、岩性油气藏以及复合油气藏。研究认为塔河油田志留系油气藏经历多期成藏和改造过程，油气成藏可以概括为“多期充注、多期调整、晚期定型”。构造及断裂发育程度控制了油气的运聚及分布，志留系断裂活动期次和油气充注期次一致，断裂的发育程度控制了志留系油气运聚；河口砂坝和潮汐水道等相带发育的优质储层控制着油气的富集；油气主要富集在志留系剥蚀尖灭线附近形成的圈闭中。塔河油田构造地层类型油气藏以在塔河南部地区为有利区，志留系原生油气藏主要分布在托普台地区。

Abstract: The Silurian oil and gas reservoir types include stratigraphic, lithologic and compound ones in the Tahe Oil Field. Studies indicate that the Silurian reservoirs have experienced multiple stages of hydrocarbon accumulation and reconstruction, which can be concluded as "multiple stages of hydrocarbon charging, multiple stages of adjustment, late-stage formation".The generation degree of structures and faults controlled the migration and distribution of oil and gas. The active stage of fractures in Silurian matched with hydrocarbon charging stage, and the generation degree of fractures controlled the migration and accumulation of oil and gas in Silurian. The favorable reservoirs of channel mouth bar and tidal channel facies determined the enrichment of oil and gas. The traps adjacent to the Silurian erosional pinch-out line are the gathering places of normal oil. The southern Tahe Oil Field is favorable for tectono-stratigraphic reservoir exploration. The Tuoputai area of the Tahe Oil Field is favorable for primary pool exploration.
