摘　　要：提出了一种利用一口井的生产测井时间推移测井资料确定油水相对渗透率曲线的方法，该方法依据达西定律导出油水相对渗透率公式，根据物质平衡原理得出相应的含水饱和度公式，从而获得油水相对渗透率曲线。现场应用结果表明，该方法简便、实用，在非取心井获得的油水相对渗透率曲线能较好地反映油藏动态变化规律。Oil/water relative permeability is usually derived from the permeability flowing experiment of sampled core in laboratory Only some key wells have only sampled core in an oil field , which can not apply to logging interpretation during reservoir dynamic production A method to determine oil/water permeability curves using time lapse production logging data is proposed According to Darcy's Law and mass volume conservation, equations for oil/water relative permeability and water saturation are established, and oil/water relative permeability curves are determined An example of use in an oil field shows that the new method is feasible and effective The calculated oil/water permeability curves in non sampled well are fitted to the reservoir dynamic behavior
