摘　　要：通过动态腐蚀试验研究了聚合物泥浆中碳钢的腐蚀行为，对盐水泥浆中碳钢的腐蚀机理及缓蚀剂性能进行了探讨。结果表明，钻井泥浆中的溶解氧是钻具腐蚀的主要原因，氯离子以热力学方式加速腐蚀。AbstractCorrosion and protection of carbon steel in polymer drilling muds were studied by dynamic wheel corrosion testing. Results show that resolved oxygen in drilling mud is essential to the corrosion of drill pipes. Chloride promotes the corrosion by thermodynamics. The synergetic action of absorptive in hibitor and oxygen scavenger can prevent the corrosion of carbon steel in drilling muds.
