    Abstract
  • 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.
