摘 要:为提高氧活化测井解释精度,在垂直模拟井上进行了室内实验。获得了多井况(油管、套管、环空)、多介质(聚合物浓度0~2500ppm间隔500ppm)条件下的实验数据。结果显示,解释的水流量在低流量时偏高、高流量时偏低,聚合物流量的解释误差较大。基于实验数据,利用函数回归方法对氧活化测井解释结果进行校正,提出了校正公式。结果表明,通过室内实验并对实验数据进行回归分析可以提高氧活化测井解释精度。In order to improve the interpretation accuracy of oxygen activation log,laboratory experiments were carried out on vertical simulation wells.Logging data under multiple experimental conditions(tubing,casing,and annulus between them)and in multiple media(polymer concentration 0~2500ppm with 500ppm interval)were obtained.Results show that directly-interpreted flowrate of water is higher at low flowrate range and lower at high flowrate range,and the interpretation errors of polymer flowrate are relatively large.Based on the experimental data,the correction formula is proposed,by using function regression method,and the interpretation data of oxygen activation log are corrected.It turns out that the interpretation accuracy of oxygen activation log can be improved by indoor experiments and regression of data.
