Abstract:

The scale inhibition of the"friendly-to-environment "type of scale inhibiting disperser PASP and PESA has been studied.And,the compatibility and syngetic effect with PBTC and the biodegradability of PASP and PESA are investigated.A scale inhibitor TS-721,mainly composed of PASP and PESA,is developed.It is suitable for oilfield water treatment.The water quality and technology have been tested under simulated conditions.Theresu-lts show that it has excellent scale inhibitive performance.

Key words: polyaspartic acid, polyepoxysuccinic acid, scale inhibition, biodegradation

摘要：

详细研究了“环境友好”型阻垢分散剂聚天冬氨酸(PASP)和聚环氧琥珀酸(PESA)的阻垢性能、与PBTC的复配协同效应及其生物可降解性能,并开发了以其为主要成分,适用于油田水处理的阻垢分散剂TS-721。模拟现场水质和工艺条件进行试验研究,结果表明,该药剂阻垢性能良好。
