摘要: 塔河油田奥陶系缝洞性油藏原油类型丰富,包括凝析油、挥发油、中轻质黑油和重质黑油,其分布具有明显的分区分带特征.根据地质控制因素,对流体性质分布的差异进行分析表明,烃类流体性质分布的非均质性不仅与成藏过程中对烃类流体的破坏改造相关,而且也反映了缝洞性储层的非均质性特征和多期油源.以烃类流体性质分布的地质响应特征为主,兼顾油井产状相近、储层物性相似及天然能量类型相同等因素,将塔河油田奥陶系油气藏缝洞性储层划分为个流动单元,对不同单元提出了开发建议,以合理开发此类油田.

Abstract: There are many types of crude oil in Ordovician fracture-cave reservoirs of Tahe Oilfield,including condensate oil,volatile oil,normal oil and heavy black oil distributed in different regions.On the basis of geological control factors,the difference of fluid property was analyzed.The fracture-cave reservoirs have the heterogeneity and multi-period oil sources.The heterogeneity of hydrocarbon fluid property is related to the destructive reformation in the forming process of reservoirs.According to the geological response characteristics of hydrocarbon fluid distribution,the Ordovician reservoirs in Tahe Oilfield can be divided into six flow units,in consideration of the same flow unit,similar fluid characteristic,similar well performance,similar physical property of reservoir and similar natural energy.Some stimulation measures and suggestions for different flow units are presented,in order to reasonably and scientifically develop this type of oilfield.

Key words: Tahe Oilfield, Ordovician, fracture-cave reservoir, carbonate reservoir, hydrocarbon fluid, heterogeneity, flow unit
