摘　　要：为了确定不同井况、不同介质对环保型液体示踪剂的影响,利用模拟井进行了环保型液体示踪剂在清水和不同质量浓度聚合物中的标定试验,分析了其响应规律,建立了在不同井况、不同质量浓度聚合物中的流量解释图版。将解释图版转化为函数解析式,对流量校正系数进行回归,建立了解释校正图版,解决了注聚井解释误差较大、油管流量与环套空间流量不一致等问题,取得了较好的应用效果。To determine the effect of different well conditions or different media on the environment-friendly liquid tracer,the calibration experiments of environment-friendly liquid tracers in clear water and different concentration polymers are carried out in a simulated well.The response law of the environment-friendly liquid tracer in the simulated well is analyzed.The chartboard is established for flow interpretation in the media in different well conditions and with different viscosities,and the chartboard is transformed into an analytical expression of the function for the regression of flow correction factor.The interpretation correction chartboard is established,which solves the problems of large error in interpretation of polymer flooding wells,inconsistency between tubing flow rate and annular flow rate,and good application result is achieved in the oilfield.
