兩種不同VES的測(cè)試結(jié)果及分析

       兩種不同的VES轉(zhuǎn)向劑，在配方條件下，在140度和150度條件下2個(gè)小時(shí)的測(cè)試結(jié)果如下：

       測(cè)試方法以及測(cè)試結(jié)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   測(cè)試方法

I. Testing Methods

1、基液配制：在20%鹽酸以及其它助劑配合條件下進(jìn)行測(cè)試。

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

2、流變性能測(cè)試

將殘酸洗液轉(zhuǎn)移到流變儀中，將溫度從25℃提高到140℃溫度，升溫溫度梯度為3℃/min，剪切速率為100s^-1。升溫至140度后，保持溫度2個(gè)小時(shí)，整個(gè)測(cè)試共計(jì)時(shí)間大約150分鐘。

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.

    上面兩個(gè)圖譜，是兩種不同VES的圖譜。兩個(gè)測(cè)試檢測(cè)配方相同，圖1溫度是140度兩小時(shí)、圖2溫度是150度兩小時(shí)。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.

     圖1顯示，隨著時(shí)間的持續(xù)，粘度持續(xù)下降，如果時(shí)間再延長(zhǎng)，粘度還會(huì)持續(xù)減小，其原因是功能性基團(tuán)在惡劣檢測(cè)條件上，功能基團(tuán)持續(xù)不斷遭到破壞，粘度就呈一直下降趨勢(shì)。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.

       圖2顯示，隨著時(shí)間的持續(xù)，粘度并未隨著時(shí)間的延續(xù)呈明顯下降趨勢(shì)，而是平行于橫軸，說明在惡劣檢測(cè)條件上，功能基團(tuán)持續(xù)發(fā)揮作用，并未遭到破壞。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.
