摘　　要：介绍了原油预脱水剂 (名称为 L GS 2 )的作用机理、化学组份、性能评价和矿场试验应用情况 .L GS2原油预脱水剂是针对特高含水期采出液处理费用高、外输原油含水高和处理后污水含油高等弊端而研究和试验应用的 .经过对孤四联合站的现场试验应用 ,在药剂成本下降 1 5 %的前提下 ,外输原油含水由试验前 1 .3 2 %下降到 1 .2 0 % ,外输污水含油由试验前的 3 70 mg/L 下降到 3 4.7mg/L.试验结果表明 :对特高含水期采出液采用预脱水剂与破乳剂配合使用 ,在成本管理和技术指标上均得到较大改观 .The action mechanism,chemical component,performance evaluation and field experiment of LGS2 oil predehydrator have been studied.It can be used for the high expense in high water cut stage,the high water cut of output oil and the high oil cut of wastewater after treatment.After the field experient in Gu4 unit,we found when the medicine cost decrease 15%,the water cut of output oil decrease from 1.32% to 1.20%,the oil cut of output waste water decrease from 370mg/l to 34.7mg/l.the experiment result show,in high water cut stage,matching using predehydrator and breaker of emulsion to treat the product fluid is very good on the cost management and technical index.
