Bridge-type concentric measuring, adjusting and sealing examination integrated testing instrument

The invention belongs to the technical field of stratified water injection of oil fields, and particularly provides a bridge-type concentric measuring, adjusting and sealing examination integrated testing instrument, comprising an upper joint, a flow measuring mechanism, a main body control mechanism, a power transmission mechanism, a tool positioning mechanism, a measuring, adjusting and sealing examination switching mechanism, a sealing examination mechanism and a flow adjusting mechanism which are connected sequentially from top to bottom. An outer barrel is arranged on the outer sides of the main body control mechanism and the power transmission mechanism, and the upper end of the outer barrel is connected with the flow measuring mechanism while the lower end of the same is connected with the tool positioning mechanism. The instrument has functions of sealing examination of a packer and stratified flow course measuring and adjusting. After the instrument is lowered into a well and docked with a water distributor through a cable, the packer is subjected to sealing examination, a stratified distribution process is performed on the water distributor directly after sealing examination, and only one time of downhole operation is needed in the whole process, so that operation processes are simplified, stratified well injection testing efficiency is improved, and downhole operation risk and construction expense are lowered.
