摘　　要：BS-2 E 是以水为溶剂、过氧化物为引发剂、由顺丁烯二酸酐与乙烯类单体合成的共聚物复配以有机磷酸盐并添加其它助剂而成的新型钡锶离子稳定剂。该剂可抑制和减轻油田集输系统,油井及注水地层的硫酸钡锶结垢,元腐蚀,不伤害地层,用量小,使用方便。在矿场应用已取得了显著的生产和经济效益。The stabilizer for Ba^(++) and Sr^(++) in mineralized waters,BS-2 E,is composed of a spe- cially synthesized maleic acid copolymer as basic ingredient,an organic phosphate and surface- active and other additives.The laboratory performance evaluation shows that this new water- treating agent can inhibit generation of barium/strontium sulfates scale and of calcium sulfate scale as well,causes no formation damage,is not corrosive,and does not inter- fere or be interfered with other water-treating chemicals commonly used in Cbangqing Oil Field in ordinary concentrations.In high solution concentrations,however,BS-2 E will react with bactericide 1227 and be precipitated.The adsorption of BS-2 E,mainly of the copolymer in it,in porous media is significant.The field tests on BS-2 E in metering and injection stations and in producing wells are successful.BS-2 E is to be used instead of Visco-953,Nalco co.,USA.
