苏丹3/7区输油管线原油降凝剂研究
|
摘要
苏丹3/7区块原油凝点高,流动性差,导致输油管线输油能力下降,已经影响油田生产和管输安全,针对苏丹3/7区输油管线原油,本文对四类35种降凝剂进行了评价,结果表明:含氮聚合物类降凝剂JNM05降凝效果最好,其次为酸酐类降凝剂降凝JNH06,再次为聚丙烯酸酯类降凝剂JNE12,EVA类降凝剂对其降凝效果较差;降凝幅度随着处理温度先增加后不变,最佳处理温度为90℃;降凝幅度随着加剂量增加先增加后降低,加剂量为1000mg/L时,含氮聚合物类降凝剂JNM05使苏丹3/7区管输原油凝点降低最大为9℃。
The crude oil produced from Sudan Block 3/7 is with high pour-point and viscosity.The bad rheology?of the crude oil has already caused high energy consumption,reduced transportation capability?and affected the operation safety of pipeline.In this paper four types of 35 kinds pour point depressants were tested in order to screen out better dispersant.The results showed that compared with polyacrylate,polymer with anhydride and EVA,polymer with Nitrogen as pour point depressant had best effect of pour point depression.The extent of pour point depression decreased with the increasing of treatment temperature,the optimal treatment temperature was 90℃.In addition,the extent of pour point depression increased first and then decreased with the increase of dosage.When the dosage was 1000 mg/L,the pour point of crude oil produced from Sudan Block 3/7 could reduce 9℃when using JNM05 polymer with Nitrogen pour point depressant.
