[0001] This utility model relates to the field of water distributor technology, and in particular to a downhole drop-and-retrieve wavecode water distributor. Background Technology

[0002] With the continuous development of oil and gas fields, the pressure and oil content of oil reservoirs are constantly decreasing, and the production of oil wells is continuously declining. In order to compensate for the formation deficit caused by crude oil extraction and achieve high and stable oil production, wavecode water distributors are used to inject water into the oil reservoir to maintain the reservoir pressure. For example, as shown in a wavecode communication downhole intelligent water distributor in Chinese patent application number CN202420182383.8, a flow channel, a water injection channel, and an installation cavity are respectively set inside the casing. The flow channel is used to ensure that water can flow freely between the various water distributors in the well, ensuring the orderly implementation of stratified water injection in the well. The water injection channel and the installation cavity are used to install the various components of the water distributor, and under the action of the water injection channel, water can also be drawn out from the water distributor to achieve the purpose of water injection.

[0003] However, when the wavecode water distributor is placed into the oil well and water is injected in layers, the lack of a support mechanism for the wavecode water distributor makes it impossible to provide stable support for the intelligent water distributor, which can easily cause it to shake during use, thereby reducing the effectiveness of the intelligent water distributor.
