盐穴注采气井腐蚀监测现场试验

Field test of corrosion monitoring in production well of salt cavern gas storage

国内盐穴储气库部分注采井已投产运行多年,为保障天然气市场用气保供和应急调峰发挥了重要作用。但对于注采井筒腐蚀监测问题,目前尚未开展过相应试验或分析。针对该研究现状,为加快推进盐穴储气库井筒监测技术体系建设,结合现场条件和技术需求,采用挂片监测的方法对注采生产井进行了腐蚀监测现场试验,并基于试验结果完成了相应的数据处理和分析评价。研究可为现场生产分析及运行评价提供技术支持。

Part of production wells in domestic salt cavern gas storage have been put into operation for many years, which played an important role in guaranteeing gas supply and emergency peak-shaving for natural gas market.However, any tests or analysis of corrosion monitoring about production wellbore have not been carried out.According to current situation and technical requirements,to accelerate the construction of monitoring technology system of production wellbore in salt cavern gas storage,a field test of corrosion monitoring on gas injection-production well based on hanging slice method has been conducted,which was followed by data processing and analysis evaluation.The research can provide technical assistance for field analysis and operation evaluation on production.
