| 摘 要： | 分析了地层水腐蚀油井水泥的机理,并通过大量试验研究,开发出了密度为1.30—1.50 g/cm~3的低密度水泥浆体系。同时在模拟腐蚀性地层水中,对该体系水泥浆凝结硬化形成的水泥石试件的耐久性和浆体的综合工程性能进行了评价。结果表明,该低密度水泥浆体系耐地层水腐蚀能力强,综合工程性能良好,可满足易漏浅井防止腐蚀性地层水腐蚀套管外壁的固井要求。

| Abstract: | Casing failure is very serious because of the corrosionto the outside wall by formation water in Changqing Oilfield. Low weight cement slurry was developed and evaluated on the anti-corrosive property. It was shown that the cement slurry could effectively inhibit the physical and chemical corrosion on casing, and improve the cementing quality greatly. |

| Keywords: | casing corrosion corrosion control cement composition cementing cement slurry |
