[0002] In the water injection work of oil and gas wells, an important task is testing and allocation. Especially for layered water injection wells, the measurement and adjustment process is very complex. Since the structure of the early water injection system uses a single allocation tool to repeatedly allocate the downhole water distribution working barrel among multiple water injection layers, that is, after the measurement and adjustment of the current layer are completed, the measurement and adjustment of the next layer are carried out, and after completion, it is necessary to return to the previous layer for fine adjustment to achieve the purpose of meeting the standard of the injection volume of multiple layers at the same time. Therefore, the more layers of the water injection well, the more times of allocation, and the more cumbersome the layer-by-layer repeated allocation. At present, such an allocation process has complex operation steps, high labor intensity, long operation time, and it is very difficult to meet the requirements of injection accuracy.

[0003] With the development of wireless intelligent water injection technology and processes, especially the emergence of wireless intelligent water injection systems, the efficiency and accuracy of layered water injection have been greatly improved.
