In order to solve the problem of liquid loading, some water-produced gas wells use intermittent production mode to produce: shut in gas wells to restore energy during the closing phase, and open up to carry the liquid to surface by the high velocity gas during well opening phase, which is cost effective. However, some wells need frequent opening and closing or adjusting gas flow, manual opening and closing is easily influenced by external interference factors (road conditions, weather, public relation issue, etc.), and cannot guarantee production time for intermittent producing well. In order to realize the remote-control and automation for these wells, the remote-control automated needle valve intermittent production system was developed and successfully applied to the L well block. The gas rate, production time and economy before and after the smart needle valve installed was compared to do the performance assessment. The results show that: (1) the stability of the remote-control automated needle valve intermittent production system is good, and it can meet the requirments of the remote automated opening and closing of gas wells. (2) After the installation of the remote-controlled automated needle valve system, 71% of the gas wells have a stable gas increase, 100% of the gas wells have a higher well opening time, and the liquid unloading in the gas wells has been significantly improved. The average gas production increased from 1.75×104 m3/d to 1.87×104 m3/d, which was 6.86% higher than that before installation. The well opening time of 7 wells increased by 5.16% on average. (3) Compared with manual operation, the comprehensive economic performance of the remote-controlled automated needle valve opening system is more excellent. The remote-controlled automated needle valve opening system can remotely intelligently control the intermittent production of gas wells, which has significant economic benefits and high application value and worth further spreading.
