With the production of natural gas and the decrease of formation energy, the number of intermittent gas wells is increasing. In view of the problem that the increase investment is not proportional to the income of intermittent production gas wells that are exhausted but still have a certain gas production. Based on the traditional single well monitoring system and Mitsubishi FX series programmable logic controller(PLC), an intelligent monitoring system for well pattern of intermittent production gas wells was developed. The system connects individual gas wells to form a well pattern. Taking Mitsubishi PLC as the system center, it coordinates the five sub modules of data acquisition, monitoring and logic processing, data transmission, emergency valve system and power supply, so that the data of the whole well station could be transmitted to the control terminal in real time. The results showed that the system could realize the real-time data monitoring of the whole life cycle of gas wells in the whole well station with low cost investment, especially for intermittent production gas wells, and could realize the automatic acquisition of failure saturation in the later stage. It greatly improved the real-time monitoring effect of the well station, the development degree of intermittent production gas wells and energy-saving effect.
