应用羟基铝防塌钻井液的技术关键是要添加缓蚀剂。室内静态、动态试验表明,T81-35缓蚀剂是较好的防塌钻井液缓蚀剂,其效果优于美国专利缓蚀剂A-130。
Application of hydroxy aluminum anti-collapse drilling fluid technology is the key to add corrosion inhibitors. Indoor static and dynamic tests show that T81-35 corrosion inhibitor is a good anti-collapse drilling fluid corrosion inhibitor, the effect is better than the US patent corrosion inhibitor A-130.
