低产水平井油水两相流阵列持水率计实验研究

低产水平井产出剖面测井中,选择合理的持率测井资料及计算方法可提高测井资料解释精度。结合长庆油田水平井低产量的特点,在剖析阵列持水率计测井原理的基础上,采用多相流动模拟实验装置开展模拟实验研究。研究表明,低流量情况下与中心电容持水率计相比较,采用阵列持水率计测井资料计算的持率结果更接近关井持率值;随含水率的增加,采用阵列电阻持水率计测井数据计算的持率结果更接近关井持率值。研究结果为低产水平井产出剖面生产测井资料的选择与精细解释奠定了基础。

Experimental Study on Oil-water Two-phase Flow Array Water Holdup Tool in Horizontal Well

It is very important to select reasonable holdup logging data and calculation method to improve logging data interpretation accuracy of low yield horizontal well production profile logging .Combined with the characteristics of low yield in the horizontal wells in Changqing oilfield and based on analyzing the logging principle ,a simulation experiment is carried out with multiphase flow simulation experiment device . The research shows that under low flow conditions ,the calculated results of the array water holdup tool's logging date are more closer to the experimental well shut-in water holdup than that of the central capacitance holdup tool's data .As well as ,with the increase of water content ,the calculated results of the resistivity array tool's logging data is more close to the well hold rate . The results of the study provide foundation for the selection and precise interpretation of the low yield horizontal well production profile data .
