一种环保型原油脱钙剂及其制备方法
摘要：
一种环保型原油脱钙剂及其制备方法涉及制备一种性能稳定的环保型绿色聚醚类多元共聚物原油脱钙剂，该原油脱钙剂具有优异的脱钙性能，是由聚醚氨基酸酯反应单体、丙烯基脲及含乙烯基不饱和双键单体进行自由基共聚而得，其结构通式为：其中：A为含乙烯基不饱和双键单体共聚后的重复结构单元，R为或‑CH2‑SH或‑(CH2)2‑CONH2，聚合度x为2～500，聚合度y为2～500，聚合度z为2～500，重复单元m为3～100。
摘要（英）：

The invention relates to an environment-friendly polyether multipolymer crude oil decalcifying agent with stable performance, in particular to an environment-friendly crude oil decalcifying agent and a preparation method thereof. The crude oil decalcifying agent has excellent decalcifying performance, and is prepared from polyether amino-acid ester reaction monomers, allyl thiourea and unsaturated double-bond monomers containing vinyl through free radical polymerization. The general structural formula is shown in the description, wherein A is a repetitive structure unit generated after copolymerization of the unsaturated double-bond monomers containing vinyl, R is -CH2-SH or -(CH2)2-CONH2, the polymerization degree x is 2-500, the polymerization degree y is 2-500, the polymerization degree z is 2-500, and the repetitive unit m is 3-100.
