摘　　要：含油幅度1600 m的裂缝性油藏是油藏地质、油田开发的全新研究对象。通过录井岩屑薄片制作、岩电柱状对比分析技术,建立岩性和储层定量识别和划分标准,综合研究油藏天然能量大小、储层润湿性、驱油效率、原油物性后认为,采用先期直井试注,后期转入水平井全面注水、底部注水、渐次上移是较合理的开发方式,预计较衰竭式开采提高采收率12.1%。This paper studies a fractured reservoir with 1600m oil-bearing relief through mud logging cutting slice and litho-electro column correlation to establish quantitative standard of identification and division of lithology and reservoirs.It has been concluded after comprehensive study on reservoir natural energy,wettability,displacement efficiency and oil property that rational development strategy is early test injection with vertical well,then converting to full scale water injection from below in horizontal wells.The predicted recovery factor is 12.1%higher than that of natural depletion recovery.
