At present, China’s development of oilfield automation and intelligence has become a trend. Efficiency and benefit are very important for every aspect of oil extraction, and they are closely linked. Then in the process of oil extraction, oil pressure, flow rate, temperature, load, location and other data are important parameters of efficiency and benefit, which are directly related to the stability of oilfield production and the quality of crude oil.
Due to historical reasons and actual topographical conditions, oil wells are often moved, so the communication lines buried in the ground will be completely damaged, and the annual maintenance cost of an oil field is as high as several million. Therefore, it is extremely urgent to solve the problem that the line is not damaged due to the transfer of the oil well location and the oil well data can be transmitted to the monitoring station in time.
Use wireless technology to form a wireless sensor network to realize oil field production management and oil well data monitoring, and achieve informatization and automation. While improving work efficiency, it also improves the working conditions of workers. Once you find that there is a problem with the data, you can immediately determine which oil well has the problem and solve it as soon as possible. There will be no external maintenance costs due to the location of the oil well, and it is truly loss-reducing, fast and convenient. It is suitable for the wireless transformation of old oilfields, saving line maintenance costs, using global open frequency bands, without incurring any additional costs. One-time installation and long-term use, once and for all, convenient for maintenance and replacement.
The company’s wireless communication module adopts the latest generation of wireless radio frequency chips that are currently industry-leading and widely used. It is designed for low power consumption in various ISM/SRD application-free frequency bands below 1G, such as 315M/433M/868M/915M and other frequency bands. Wireless digital communication module. This series of modules is an industrial-grade standard product that can work in extremely harsh oilfield environments. It has the characteristics of low cost, small size, stable work, and good product consistency.

2. System introduction
RTU collects sensor data and transmits it to the monitoring station through the wireless communication module. The station uses the industrial TCI/IP network or GPRS network to transmit to the oilfield center in real time.
The system can also transform all sensors into wireless sensors, truly achieving wirelessization of the overall equipment. (The specific plan is to be determined)
