高温VES转向剂测试

VES转向剂-2025.3.15  测试方法及测试结果

       VES转向剂-2025.3.15，在配方条件下，在140度条件下2个小时仍保持200CP以上粘度，保证了140度2小时保持75CP的粘度要求。

       测试方法以及测试结果如下：

         VES Diverting Agent - March 15, 2025. Under the specified formulation conditions, the agent maintained a viscosity of over 200 cP for 2 hours at 140°C, thereby ensuring compliance with the viscosity requirement of 75 cP under the same temperature and duration.

The testing method 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.
