The packer is mainly used for realizing the requirements of packing a production layer or a construction target layer, and preventing fluid and pressure between layers from interfering with each other to influence the effect of measure operation. The packer is an underground tool which cannot be obtained in oil field production, plays an important role no matter in operation links such as oil extraction, water injection, target layer transformation and the like, and along with the deepening of oil field development, the using amount of the packer is continuously increased, and particularly in the field of fracturing, the low-permeability and compact oil-gas reservoir multilayer and multi-section effective use is realized by using the packer. However, the frequent sealing losing of the packer in the using process seriously affects the fracturing scale and the fracturing effect, and meanwhile, the sealing losing problem of the packer also causes the failure of the technologies of layered oil extraction, layered water injection and the like, thereby seriously restricting the high-efficiency production of the oil field.

In fact, no matter in fracturing or water injection construction, because tubular column and packer can alternate work under different operating modes, same working method also has multiple changes, this will lead to in the oil pipe, outer temperature and pressure take place to show the change, and this kind of change can arouse the change of packer tubular column atress often, and then lead to the tubular column extension or shorten, the tubular column wriggle promptly, at high temperature, in high pressure and the complicated deep stratum, the tubular column wriggle can influence the downhole work effect of the system of packer, lead to destroying even, the packer is when actual work, because sucker rod reciprocating motion can collide oil pipe and produce the vibration, cause unexpected deblocking of packer or because the wriggle of tubular column, lead to sealed inefficacy. In fact, the main reason for the creeping and sealing losing of the packer is vibration, but the packer cannot be actually detected due to the fact that the packer is located at the position of thousands of meters underground, and in order to research the sealing losing mechanism of the packer after being subjected to vibration and find out a solution, a simulation device is designed, and through the simulation device, underground working conditions are simulated as much as possible and the state of the packer is detected, so that data support is provided for improving and optimizing the structure of the packer and preventing the sealing losing.
