The utility model relates to a liquid test system is produced to horizontal well of cooperation coiled tubing operation. This system includes ground numerical control device, cable, coiled tubing, cable head and horizontal well sectionalization test pipe cluster, coiled tubing built -in cables, the one end and the ground numerical control device of cable are connected, and the other end passes through the cable head and links to each other with horizontal well sectionalization test pipe cluster, horizontal well sectionalization test pipe cluster is including the flexible nipple joint, telemetering measurement nipple joint, screen sub, upper packer, horizontal well product liquid tester, the lower packer that connect gradually, the direct test of segmentation through using this test systemcan accomplish horizontal well flow, moisture, temperature, pipe inner pressure, outside of tubes pressure still can realize the test of stratum repressuring to can pass through cable real time transport to ground numerical c
