两种不同VES的测试结果及分析

       两种不同的VES转向剂，在配方条件下，在140度和150度条件下2个小时的测试结果如下：

       测试方法以及测试结果如下：

         Two different VES diverting agents, under identical formulation conditions, were tested at 140°C and 150°C for 2 hours. The testing methodology and results are as follows:

一   测试方法

I. Testing Methods

1、基液配制：在20%盐酸以及其它助剂配合条件下进行测试。

1. Base Fluid Preparation
The test was conducted under the conditions of 20% hydrochloric acid combined with other additives.

2、流变性能测试

将残酸洗液转移到流变仪中，将温度从25℃提高到140℃温度，升温温度梯度为3℃/min，剪切速率为100s^-1。升温至140度后，保持温度2个小时，整个测试共计时间大约150分钟。

2. Rheological Performance Testing
The residual acid solution was transferred to a rheometer. The temperature was increased from 25°C to 140°C at a heating rate of 3°C/min under a shear rate of 100 s⁻¹. After reaching 140°C, the temperature was maintained for 2 hours. The total test duration was approximately 150 minutes.

    上面两个图谱，是两种不同VES的图谱。两个测试检测配方相同，图1温度是140度两小时、图2温度是150度两小时。The two spectra above are from two different types of VES. Both tests detected the same formulation. Figure 1 was measured at 140°C for two hours, while Figure 2 was measured at 150°C for two hours.

     图1显示，随着时间的持续，粘度持续下降，如果时间再延长，粘度还会持续减小，其原因是功能性基团在恶劣检测条件上，功能基团持续不断遭到破坏，粘度就呈一直下降趋势。Figure 1 shows that as time progresses, the viscosity continues to decrease. If the duration were extended, the viscosity would continue to decline. The reason for this is that under harsh testing conditions, the functional groups are continuously disrupted, leading to a consistent downward trend in viscosity.

       图2显示，随着时间的持续，粘度并未随着时间的延续呈明显下降趋势，而是平行于横轴，说明在恶劣检测条件上，功能基团持续发挥作用，并未遭到破坏。Figure 2 shows that as time progresses, the viscosity does not exhibit a significant decreasing trend over time but instead remains parallel to the horizontal axis. This indicates that under harsh testing conditions, the functional groups continue to function effectively without being disrupted.
