摘要
采用Langmuir-Blodgett(LB)技术对新疆火烧山油田油井产出乳状液中油水界面膜的稳定性进行了研究,针对其稳定性特征设计并合成出一种高效的四元共聚破乳剂。通过分析破乳脱水率和破乳后的油中含水量评价破乳剂WH-2的破乳脱水效果,并研究了其与现场使用的破乳剂ZP-1的配伍性。室内评价结果表明:破乳剂WH-2能使采出液脱水率达到67.93%,高于现场使用的破乳剂ZP-1的脱水效果,且破乳剂WH-2与ZP-1具有较好的配伍性。现场中试结果表明:将该破乳剂与现场使用的破乳剂以质量比为1∶2、1∶4、1∶5复配使用,脱水率达到98%以上,同时降低了加药成本,并且能够降低管汇压力,增加采出液的日来液量。
Langmuir-Blodgett （LB） technique is used to study the stability of oil-water interfacial films in crude emulsion of Mount Huoshao oil field in Xinjiang.WH-2,a highly efficient quadripolymer demulsifier,is designed and synthesized based on the oil-water interfacial stability characteristics of crude emulsion of Mount Huoshao oil field.The emulsification dehydration effect of WH-2 is evaluated by analyzing dehydration rate and water content in oil after demulsification.The compatibility of WH-2 with the field used demulsifier ZP-1 is also investigated.Laboratory comparative evaluation shows that the dehydration rate of produced fluid can reach 67.93％ by using WH-2,which is higher than ZP-1.In addition,the new demulsifier WH-2 has a good compatibility with ZP-1.The site test results indicate that when WH-2 and ZP-1 is mixed with a mass ratio of 1 ∶ 2,1 ∶ 4 and 1∶ 5,the dehydration rate is up to 98％.The dosing costs and manifold pressure will be reduced.The daily volume of produced fluid will be increased at the same time.
