Oilfield water injection is an effective method for maintaining reservoir pressure, achieving high and stable production, and improving overall field development efficiency. However, due to the presence of multiple reservoir layers with significant differences in physical properties and varying water intake capacities, cross-layer water channeling often occurs during injection. This leads to inefficient and ineffective water flooding. Furthermore, the existing third-generation water injection technology involves heavy workloads, long water distribution cycles, and lacks real-time monitoring capabilities, failing to meet the requirements of big data applications.
Therefore, the Cable-Less Intelligent Zonal Water Injection System has been proposed, representing the fourth generation of zonal water injection technology. The data it collects includes conventional technical parameters such as zonal pressure and flow rate. By integrating wireless communication, zonal injection technology, and AI powered by big data analytics, the system enables remote automatic monitoring of each injection zone, precise measurement and regulation of reservoir intervals, refined management, and real-time monitoring of flow rate and pressure. This ensures effective water flooding and supports sustained high and stable oilfield production.
