摘要:
根据东营－辛店管道所输混合原油的胶质、沥青质含量和蜡晶分布特点，研制了 BEM-JN 系列油基降粘剂，主要成分为聚合物和表面活性剂，其中非极性聚合物为降凝剂的有效成分，主要针对
原油中的蜡起作用，极性较强的聚合物和表面活性剂则针对原油中的胶质、沥青质起作用，原油粘度的降低是两类组分综合作用的结果。分别考察了 BEM-JN 降粘剂和 BEM-3 降凝剂在不同热处理温度下对东营原油库原油的降粘效果，结果表明：相对较高的热处理温度有利于提高两种化学剂的降粘效果，而相对较低的热处理温度和相对较高的测试温度将使降凝剂表现出增粘效果。室内实验和现场应用试验证明：BEM-JN 降粘剂对于东营－辛店管道所输混合原油具有较好的降粘效果，其应用可满足该管道低输量安全运行的需要。

Abstract:

According to the characteristics of mixed crude oil transported through Dongying-Xindian Oil Pipeline in gel and asphaltene content and wax crystalline distribution，BEM-JN series oil-based viscosity depressant is prepared，which is consisted of polymer and surfactant as main components. The main effective component is nonpolar-polymer，which functions on the wax，while the strong-polar-polymer functions on the gel and asphaltene. The reduction of crude oil viscosity is the result of these two kinds of comprehensive effects. The viscosity reduction effects under different heat treatment temperature by BEM-JN and BEM-3 are studied， respectively. The results show that higher heat treatment temperature is helpful to enhance the viscosity reduction effect for the two chemicals，while lower treatment temperature and higher test temperature will lead to tackify. The indoor and field experiments show that BEM-JN has good performance in the light of the crude oil in Dongying-Xindian Oil Pipeline，and can meet the demands in safe running under low throughput for the pipeline.
