为了防止地层酸化时土酸对钢铁设备及井下油、套管的腐蚀，研制了Ｖ１型土酸酸化缓蚀剂。该剂是以一种有机胺盐、炔醇和商品缓蚀剂Ｄｏｄｉｇｅｎ９５为主要成分的复配型缓蚀剂，适用于各种土酸酸化体系。本文介绍了该剂的室内性能评价和现场试验结果。 In order to prevent the formation of acid acidity when the acid on the steel equipment and downhole oil, casing corrosion, developed a V 1 soil acidizing corrosion inhibitor. The agent is based on an organic amine salt, acetylene alcohol and commercial corrosion inhibitor Dodigen 95 as the main component of the compound corrosion inhibitor, suitable for a variety of soil acidification system. This article describes the agent’s indoor performance evaluation and field test results.
