试验观察了冀东油田高尚堡Es组原油与现场常规土酸生成酸渣情况,考察了酸类型、酸浓度、Fe~(3+)、缓蚀剂等对酸渣生成的影响。结果表明现场用常规土酸与地层原油接触生成酸渣,酸渣的生成是强酸、Fe~(3+)”、缓蚀剂等因素共同作用的结果。有效的抗渣方法是综合采用降低酸强度、使用抗渣剂、消除Fe~(3+)的影响、使用配伍性好的酸液添加剂等控制酸渣生成途径的防治方法。 Experiments were conducted to observe the formation of acid dross from the Es crude oil of Eschao Es Group in Jidong Oilfield and the conventional acid in the field. The effects of acid type, acid concentration, Fe ~ (3 +) and corrosion inhibitor on the generation of acid dregs were investigated. The results show that acid mud is formed by the contact of conventional earth acid and formation crude oil, and the formation of acid slag is the result of the interaction of strong acid, Fe 3+, corrosion inhibitor and other factors.The effective method is to reduce the acid Strength, the use of anti-slag agent to eliminate the impact of Fe ~ (3 +), the use of good acid additives and other control methods to control the generation of acid residue prevention methods.
