Abstract: In view of the characteristics of Henan oil field, such as widely - scattered wells, inconvenient transportation and high management cost, a suit of pump well equipment on automatic monitoring system has been developed. With the help of this system, the running status data, for example, loading, fluid level, temperature and pressure can be collected, after that these data will be transmitted to the monitoring center through GPRS wireless communication network. After analysis and processing, the monitoring center can make up management measures as soon as possible in order to guarantee the normal production of wells.
