摘要
合成了一种新型的噻唑类缓蚀润滑剂SZJ-1,并采用失重法、电化学方法等研究了缓蚀润滑剂SZJ-1在高浓度盐酸中对N80钢的缓蚀性能,采用润滑仪评价SZJ-1在钻井泥浆中的润滑性能,探讨了其在N80钢表面的吸附行为。结果显明,该缓蚀润滑剂具有良好的缓蚀和润滑性能,能将腐蚀控制在3g/(m2·h)以下,润滑系数降低率达到80.67%,是一种性能优良的缓蚀润滑剂。
A new-type of thiazole corrosion inhibitor and lubricant SZJ-1is synthesized.Material's corrosion inhibition to N80 steel in the hydrochloric acid is characterized by weight-loss and electrochemical method.The lubrication performance in the drilling fluid is evaluated by the lubrication device.Besides,its adsorption behavior on the surface of N80 steel is discussed.The results show that the corrosion inhibitor and lubricant has excellent corrosion inhibition and corrosion is controlled below the 3g/(m^2·h)and lubrication coefficient reduction rate is 80.67%.As a result,corrosion inhibitor and lubricant SZJ-1is a kind of promising agent.
