Testing system

The invention provides a testing system. The testing system comprises a packer and a testing device arranged at the periphery of the packer in a sleeving mode; the packer comprises a central pipe, and an internal through hole is formed in the central pipe; the packer further comprises a liquid passing channel which is formed in the pipe wall of the central pipe and communicates with the internal through hole. According to the technical scheme, the problem that in the prior art, the actual working condition of the packer under a well is difficult to simulate can be solved. 本发明提供了种试验系统。试验系统包括封隔器和套设在封隔器外周的试验装置，封隔器包括中心管，中心管具有内部通孔，封隔器还包括开设在中心管的管壁上的与内部通孔连通的过液通道。本发明的技术方案可以解决现有技术中的难以模拟封隔器在井下的实际工况的问题。
