【摘要】：針對聚合物驅(qū)后油井采出液中含有的聚合物導(dǎo)致聯(lián)合站脫水和污水處理困難的問題,分析了國內(nèi)各油田聚驅(qū)采出液脫水破乳劑的現(xiàn)狀,依據(jù)原油乳狀液凝膠的結(jié)構(gòu)裂降和結(jié)構(gòu)恢復(fù)行為對其觸變性影響的原理,采用多乙烯多胺、松香胺、有機(jī)醛、胺、苯酚等的反應(yīng)物為起始劑的聚醚類破乳劑按一定比例復(fù)配后,再引入微量的烷基酰胺丙基甜菜堿、氯化亞鐵、維生素C、氟碳表面活性劑FN-3,得到聚驅(qū)原油采出液脫水低溫破乳劑,利用電中和機(jī)理,實(shí)現(xiàn)了聚驅(qū)原油采出液低溫破乳脫水�，F(xiàn)場藥劑質(zhì)量濃度在50~70mg/L、脫水溫度40~43℃的條件下,原油脫水后含水率小于0.2%,污水含油質(zhì)量濃度小于50mg/L。
[Abstract]:In view of the problem that the polymer contained in the produced fluid of oil wells after polymer flooding leads to the difficulty of dehydration and sewage treatment in the combination station, the present situation of dehydration and demulsifier for the produced fluid of polymer flooding in various oil fields in China is analyzed. According to the principle that the structure crack drop and the structure recovery behavior of crude oil emulsion gel affect its thixotropy, polyether demulsifier with polyvinyl polyamine, rosin amine, organic aldehydes, amine and phenol as initiator was used to compound polyether demulsifier in a certain proportion. The low temperature demulsifying agent of polymer flooding crude oil production liquid was obtained by introducing a small amount of alkyl aminopropylbetaine, ferrous chloride, vitamin C and fluorocarbon surfactant FN-3. The low temperature demulsification and dehydration of the produced solution of polymer flooding crude oil was realized by using the mechanism of electric neutralization. The water content of crude oil after dehydration is less than 0.2 and the mass concentration of oil in sewage is less than 50 mg / L under the conditions of 50 ~ 70 mg 路L ~ (-1) mass concentration and 40 ~ 43 鈩，
