为了获得适用于延长油田的配伍性良好的水处理剂,通过考察缓蚀剂、杀菌剂与阻垢剂、絮凝剂、破乳剂复配后的缓蚀性能和杀菌性能,研究了常用油田水缓蚀剂与杀菌剂、阻垢剂、有机絮凝剂、破乳剂之间的配伍性。结果表明,两性含膦咪唑啉缓蚀剂SW-629 与无机类絮凝剂聚合氯化铝、聚合硫酸铁,阻垢剂氨基三甲叉膦酸ATMP、共聚物类HQ-1 和破乳剂聚醚类SW-101 的配伍性较差;阳离子咪唑啉缓蚀剂SW-639 与杀菌剂异噻类SW-906、季铵盐类1227,絮凝剂聚合硫酸铁、阴离子聚丙烯酰胺XN-2,双1,6-亚己基三胺五甲叉膦酸BH-1、钡锶阻垢剂HQ-2、聚酯类SW-102 破乳剂的配伍性不好;双咪唑啉缓蚀剂SW-649 与二氧化氯杀菌剂,聚合氯化铝、聚合硫酸铁絮凝剂,ATMP、钡锶阻垢剂HQ-2,聚酯类SW-102 破乳剂的配伍性较差;异噻类SW-906 杀菌剂与絮凝剂聚合铁、阴离子聚丙烯酰胺XN-2,双咪咪唑啉缓蚀剂SW-649 配伍性较差。含膦类咪唑啉缓蚀剂SW-629、有机膦阻垢剂(双1,6-亚己基三胺五甲叉膦酸BH-1 和乙二胺四甲叉膦酸钠EDTMPS)、异噻类SW-906 杀菌剂受其他药剂影响较小且相互之间配伍性良好,可以在延长油田推广应用。表7 参12
In order to obtain the oil field water treatment agent suitable for the Yanchang oilfield with good compatibility,the corrosion performance and bactericidal performance of corrosion inhibitor,fungicide after being compounded with scale inhibitor,flocculant and demulsifier were investigated,and the compatibility of the treatment agents were studied. The results showed that the compatibility of phosphine imidazoline inhibitor SW-629 with inorganic flocculants including poly aluminum chloride(PAC)and polyferric sulfate(PFS),scale inhibitors including amino trimethylene phosphonic acid ATMP and copolymer HQ-1,polyether SW-101 demulsifier was poor;the compatibility of the cationic imidazoline inhibitor SW-639 with the fungicides including isothiomer SW-906 and quaternary ammonium salt 1227, flocculant including PFS, anionic polyacrylamide XN-2, bis hexamethylene triamine penta (methylene phosphonic acid) BH-1 and barium strontium scale inhibitor HQ-2,and polyester SW-102 demulsifier was not well;the compatibility of the double imidazoline inhibitor SW-649 with chlorine dioxide fungicide,flocculants including PAC and PFS,scale inhibitors including ATMP and HQ-2,polyester SW-102 demulsifier was poor;the compatibility of the isothiomers SW-906 fungicide with flocculants including PFS and anionic polyacrylamide XN-2,double imidazoline inhibitor SW-649 was bad. There was the better compatibility between phosphine imidazoline inhibitor SW-629,phosphonate scale inhibitors including bis hexamethylene triamine penta(methylene phosphonic acid)BH-1 and ethylene diamine tetra(methylene phosphonic acid)sodium EDTMPS,and isothiomer SW-906 fungicide,which could be generalized to use in Yanchang oilfied.
