摘要:
特稠油胶质、沥青质含量高，具有粘度高、密度大、流动性差的特点。目前解决特稠油的粘度问题，多采用降粘剂。但是，降粘剂溶液可能会对输油管道造成腐蚀。针对河南油田采出特稠油的性质，采用正交实验法研究了两种乳化降粘剂 AE、EC 和油溶性降粘剂 AC 的降粘效果，利用静态腐蚀失重法评价了 3 种降粘剂对 N80 钢的腐蚀程度，以对降粘剂进行优选。正交实验结果表明：最优降粘剂为EC，最佳使用温度为 70 ℃，降粘剂用量为 0.3%，油水比为 6∶4，降粘率达到 99.81%；腐蚀实验结果表明：AE 和 EC 两种降粘剂对 N80 钢均表现出很好的缓蚀效果，缓蚀率分别达到 80.42% 和 85.85%。
Abstract:

Extra-heavy oil is featured with gelatination，high content asphaltene，high viscosity，high density and poor flowability. At present， viscosity reducer is mainly used to cut down its viscosity. However，the solution of viscosity reducer will probably tend to corrode oil pipeline. In allusion to the property of extra-heavy oil produced from Henan Oilfiled，orthogonal experimental method is adopted to research the viscosity reducing effectiveness of emulsified viscosity reducer AE and EC and oil-soluble viscosity reducer AC. Static corrosion weight loss method are applied to evaluate the corrosion level of the above 3 viscosity reducers on N80 steel in order to select appropriate candidate. Results from the orthogonal experiment display that the best viscosity reducer is EC with a 99.81% of viscosity reducing rate when it is used at 70 ℃ with a 0.3% of addition volume and a 6∶4 of oil-water ratio；results from corrosion experiment show that AE and EC have sound corrosion inhibitation effectiveness and the corrosion inhibitation rates of the two reducers are up to 80.42% and 85.85%，respectively.
