Wherein, as shown in fig. 2, the circulation pipe 4 includes a base pipe 41 and a modular pipe 42 connected in series with the base pipe 41, and as shown in fig. 3, the modular pipe 42 may include at least one coiled tubing module 421, and the coiled tubing module 421 includes a coiled tubing having a specific length.

Furthermore, by modularly designing the coiled tubing modules 421 of the modular pipeline 42, even if each of the coiled tubing modules 421 comprises coiled tubing having a specific length, which may be, for example, 1500 meters as shown in fig. 2, on the one hand, calculation and selection of the circulation length may be made easier and, on the other hand, the manufacture and connection of the coiled tubing modules 421 may be facilitated.
The modular fluid circulation testing system 100 of the embodiment of the invention has smaller occupied area after capacity expansion, lower construction difficulty and cost, simpler and more convenient capacity expansion in the later period after construction, and can simulate deeper well hole environment and be popularized and used in a large scale.

Table 1 below shows the control logic of each electrically operated valve (16 electrically operated valves F1 to F16 in total) under different cycle lengths, i.e. the on-off state of each electrically operated valve on the pipeline corresponding to each basic cycle length 44 and/or each specific cycle length 45 when selected.
The required cycle length may be zero meters, or may be a superposition between at least two basic cycle lengths 44, or may be a superposition of at least one basic cycle length 44 and at least one specific cycle length 45, or may be a multiple N (N. Gtoreq.1) of the specific cycle length 45, as shown in Table 1 below.
