摘要:
新疆呼圖壁儲氣庫埋地管線輸送介質以甲烷為主,其中CO2占1.89%,采氣工況下伴有凝析油和地層水產出,埋地管道易受腐蝕影響。為掌握其腐蝕狀況以采取合理防腐措施,通過對腐蝕環境分析研究,確定其腐蝕影響因素以游離水、CO2分壓為主,還包括土壤環境、溫度、氯離子濃度和流速等。對此,儲氣庫采取“不銹鋼雙金屬復合管+3PE防腐層+強制電流”的防腐措施,每年檢修期間對埋地金屬管線進行檢測,對個別破損點及時修復維護,保證氣庫安全平穩運行。
Abstract:
The Xinjiang Hutubi gas storage is a depletion type of oil&gas reservoirs.The total length of buried injectionproduction pipelines and injectionproduction main lines is 39.4km,the medium is mainly methane,with carbon dioxide accounting for 1.89%.During the period of gas extraction,there will be accompanied by the production of condensate oil and formation water.Under the influence of the partial pressure of carbon dioxide and formation water,the buried metal pipelines is vulnerable to corrosion.For the study of corrosion status of buried pipeline and adopt reasonable anticorrosion measures,through the analysis of corrosive environment,the gas storage corrosion factors are priority to with free water,CO2 partial pressure,also including the soil environment,temperature,concentration of chloride ion and flow rate etc.In this regard,gas storage take”internal corrosion protection+external corrosion protection+cathodic protection”combination of anticorrosion,that is “stainless steel double metal composite pipe+3PE anticorrosion layer+forced current”approach.During the overhaul period,the buried metal pipeline is detected,repair and maintain the individual damaged spots in time,ensure the safe and smooth operation of the gas storage.
