针对钻具地面存放过程中腐蚀较严重的事实，采用室外挂片大气腐蚀测试法，通过缓蚀剂种类、使用浓度、ｐ Ｈ 值及复配和成膜剂协同作用等对钻具缓蚀效果的影响研究，研制开发了一种钻具地面存放防腐缓蚀剂 Ａ Ｎ Ｐ Ｊ。实践表明，该剂是一种水溶性成膜缓蚀剂，具有使用量少效果明显的特点，用量为１ ２００ ｍｇ／ Ｌ 时，缓蚀率可达９４５２ ％ ，利用其水溶液清洗钻具后，可使钻具在潮湿大气中存放半月不生锈，具有现场使用价值。
Aiming at the fact that the corrosion of drilling tool is more serious during the storage, the outdoor coupon atmospheric corrosion test method is adopted to control the anticorrosive effect of the drilling tool by using corrosion inhibitor type, concentration, p H value, compounding and film-forming agent synergism Of the impact of research, research and development of a drilling tool corrosion inhibitor corrosion deposited ANP. Practice shows that the agent is a water-soluble film-forming corrosion inhibitor, with less effect with obvious characteristics, the amount of 1 200 mg / L, the inhibition rate of up to 94 52%, the use of its aqueous solution to clean the drill After drilling tools can be stored in the humid atmosphere half does not rust, with field use value.
