The Integrative Managements of Production and Corrosion Protection for Gas Wells in A Domestic Natural Gas Field

In the middle and late stage of gas field development, stimulation and corrosion protection is severely limited by the productivity impairment and load-up, especially the corrosion of acidic media such as CO₂ and fluid erosion accelerates the corrosion rate. Combining the oil casing corrosion prevention and stimulation measures effectively, to reduce the interference between the both of them and improve the safety production efficiency of gas wells is still a sticking point in the process of developing oil field. Herein, through a comprehensive analysis of the current situation of gas well corrosion and protection, as well as the monitoring and testing results over the years, an overall plan was made in gas field, which combined with the technical requirements and systems of stimulation measures, took measures to integrate the management of stimulation and corrosion protection, realized the fine management of gas well technology measures, and promoted the high-quality development of the gas field.
