1、选取了3种油水乳状液稳定剂，分别对含水15%的番禺4-2管输混合原油的乳状液稳定性进行了对比试验。见表10-1。表10-1不同稳定剂对PY4-2原油稳定性的影响稳定剂筛选剂名加剂浓度实验温度恒温时间乳状液状态1#剂3%90℃2.8h非常稳定1#剂2%90℃2.8h非常稳定2#剂2%90℃2.8h稳定3#剂2%90℃30min部分破乳3#剂3%90℃30min部分破乳3#剂5%90℃30min部分破乳3#剂不能满足乳状液稳定性的要求；1#剂虽能满足乳状液稳定性的要求，但稳定性过强，将造成后续脱水困难。经综合

2、比选，选择2#剂作为番禺4-2乳化原油稳定剂。2#剂的主要成分为无机盐，呈微弱的碱性，对于含有H2S和CO2的番禺4-2原油有一定的中和作用。Selectthreekindsofoil-wateremulsionstabilizers,totestandcomparetheemulsionstabilityofPY4-2pipelineblendoil(with15%watercut)respectively.Seetable10-1.Table10-1differentstabilizersontheP
