氧乙烯醚 (NPE)类化学成分
Excluding such as alkylphenol ethoxylate
(APE) and nonylphenol polyethylene
Ethylene oxide ether (NPE) chemical
composition
十秒内起效实现连续混配
Take effect and achieve to
continuous mixed within 10
seconds.
D8625R为抗高盐的高效阴离子型乳液减阻剂，可在高盐盐水或返排液中使用。只需在
压裂液中少量添加（0.025-0.1%），本品即可在1分钟内实现最高达70%阻降。
D8625R10可在常用非离子或阴离子压裂液中配合使用。同时，其不含烷基酚乙氧基化
物（APE）和壬基酚聚氧乙烯醚 (NPE) ，比普通乳液型减阻剂更为绿色环保。作为一种
乳液型产品，RTK-4010在高盐或不良水质的溶液中溶解速度快（通常1分钟内），在实
际应用中可实现连续混配。
D8625R is resistance on high salt of efficient anionic emulsion Drag Reducing
Agent,It for high salt water and flowback fluid,only add small amount to
fracturing fluid(0.025-0.1%), This product can achieve up to 70% resistance drop
within 1 minute , D8625R can be use with the commonly used non-ionic and
anionic fracturing fluid ,meanwhile,it have not contain alkyl phenol b oxygen,
Base compound (APE) and nonylphenol polyoxyethylene ether (NPE), It is even
more green environmental protection than ordinary emulsion type of drag
reduction agent,, As a kind of emulsion products, D8625R dissolving speed
quakly in high salt or bad water quality solution (usually within 1 minute),it can
realize continuous mixed in the practical application.
