高温堵漏凝胶性能评价系统

凝胶堵漏具有一定的创新性和前沿性,目前还没有相关仪器准确评价凝胶堵漏所需凝胶的核心性能,为此研制出一套高温堵漏凝胶性能评价系统。介绍了新型堵漏凝胶性能评价仪器——高温堵漏凝胶性能评价系统的组成、工作原理及使用情况。该评价系统可进行实验压力自动采集,实验温度范围为室温~200℃;智能触摸屏还可以随时监测堵漏压力、最大堵漏承载压力、承载压力随时间变化情况、凝胶保持良好封堵能力时间、回压压力等实验参数,并以曲线形式显示出来;系统显示实验结果准确、直观、方便,可以打印相关曲线和数据报表。高温堵漏凝胶性能评价仪选用的加热、数据采集、数显、保温、传感器、智能电脑等设备材质精良、耐用,可进行长期、高强度的实验。

Instrument for High Temperature Gel LCM Evaluation

No instrument is available currently for the evaluation of the primary properties of gel lost circulation material (LCM), a novel additive for lost circulation control. To accurately measure the performance of this kind of LCM, an instrument system is developed. This paper introduces the composition, working mechanism and application of the system. The system acquires test pressure automatically and has working temperature ranging from room temperature to 200℃. The smartscreen of the instrument can monitor test pressure, maximum workload, change of workload vs. time, time in which the gel LCM can stop the mud loss, and backpressure, all shown in curves and printed on papers. With this system, the evaluation test can be performed accurately and conveniently, with testing results directly viewed. This heavy-duty system is made with high quality components and can be used in long-time testing.
