These devices, by integrating multiple sensors, data acquisition modules, and communication technologies, can accurately sense and transmit various parameter information of oil, gas, and water wells, providing important data for oilfield production management and decision support. However, when using parameter sensing equipment for oil, gas, and water wells, the reliance on manual and mechanical sensors is the main factor, which results in limited sensing range and poor real-time performance, making it difficult to obtain detailed parameters of the internal and surrounding environment of oil, gas, and water wells in real time.
