利用高压反应釜模拟了某油田CO2驱油环境下DPC和TK70两种内涂层的耐CO2腐蚀性能进行了评价，对比分析了涂层油管试片和涂层油管丝扣经浸泡试验前后形貌特征。结果表明，两种油管内涂层和涂层油管丝扣具有良好附着力和较强的耐腐蚀性能，对CO2腐蚀环境具有良好的适用性。
利用高壓反應釜模擬瞭某油田CO2驅油環境下DPC和TK70兩種內塗層的耐CO2腐蝕性能進行瞭評價，對比分析瞭塗層油管試片和塗層油管絲釦經浸泡試驗前後形貌特徵。結果錶明，兩種油管內塗層和塗層油管絲釦具有良好附著力和較彊的耐腐蝕性能，對CO2腐蝕環境具有良好的適用性。

The CO2 corrosion resistance of two kinds of internal coating DPC and TK70 were investigated by using the high pressure autoclave under simulated CO2 flooding environment. The comparative analysis was conducted on the surface morphologies of both tubing slice and tubing threads samples. The results indicated that two kinds of tubing coating and coating of oil tubing threads has good adhesion and corrosion resistance, which is adaptive for CO2 corrosion condition.
