Description
Technical field
It is especially a kind of for testing the examination of packing element performance the present invention relates to petroleum industry downhole tool test fixture field
Test tooling.
Background technique
The bridge plug used in oil gas field plugging technology and packer, packer be usually pressure break, be acidified, look for leakage etc. arrange
It is temporarily stayed in well when construction, just rises and come out with tubing string after having constructed, and bridge plug is in measures such as sealing oil recoveries, it
It stays in a period of time in well or is left permanently in well.Sealing function is all played, and packing element is that bridge plug and packer play sealing
The core component of effect.
Currently, having multinomial patent application about bridge plug and packing element performance testing device, such as Xu Chun swallow et al.
The packing element and packing element component test device of a kind of bridge plug, packer that design, disclose the test that mechanical property is set to packing element
Device, but the device cannot be sealed performance test together, have a single function, and also not have simulated formation temperature and pressure.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of for testing the test tool of packing element performance, solves
