Abstract

The invention discloses a coiled tubing injection head test simulative loading device and belongs to the petroleum field. The loading device comprises a set of loading injection head, four magnetic powder brakes, two gear reducers, four universal shafts, one test installation table, one connection base, a plurality of load sensors and one encoder. The four magnetic powder brakes are used for providing braking torque for the loading injection head; the connection base is used for mounting a test injection head; the plurality of load sensors are used for testing a loading force; and the encoder is used for testing the test speed and the setting depth of the test injection head. Through the above structure, the loading device can provide dynamic loading for the coiled tubing injection head test; test for injection heads with various specifications can be met through relatively-short coiled tubing trip stimulating actual on-site coiled tubing work; and the loading device provides a maximum loading test, and meets the fixation and installation of the injection heads of various structural forms.

Description

technical field [0001] The invention belongs to the field of petroleum, in particular to a test simulation loading device for a coiled pipe injector. Background technique [0002] The key components in the coiled tubing equipment: the injection head, the drum and the liquid circuit system need to undergo strict unit tests and complete machine tests after they are assembled. [0003] At present, in the testing of coiled tubing equipment, due to the lack of effective devices and methods for testing and testing, only simple operation and motion testing can be performed, and the simulated testing of coiled tubing downhole, especially the dynamic loading of the injection head, cannot be performed. SUMMARY OF THE INVENTION [0004] In order to solve the problems in the prior art, the embodiment of the present invention provides a test simulation loading device for the coiled tubing injector. Actual on-site coiled tubing operation; can meet the test of various specifications of ...
