The tight gas in the Jinqiu block is extracted using sand fracturing technology,and there are microorganisms such as sulfate reducing bacteria(SRB),saprophytic bacteria(TGB),and iron bacteria(FB)in the produced water.The risk of micro-bial corrosion was analyzed and identified;meanwhile,the microbial source and the control measures for microbial corrosion were studied.Up to now,no microbial corrosion failure occurred in the wellbores as well as gathering and transportation systems at each platform.
