补充资料:堵水剂
分子式:
CAS号:

性质:在油田开采过程中,由于水层窜槽、底水锥进或注入水、边水突进,使一些油井过早见水或水淹。为了清除或减少水淹,控制产水层中水的流动和改变水驱油中水的流动方向,提高水驱油采收率,在生产井或注入井上进行封堵出水层段所采用的化学处理剂称为堵水剂。从施工技术上来划分,可分为选择性堵水、非选择性堵水、注水井调剖和区块整体堵水。从化学剂结构和作用机理可分为(1)无机盐类,如硅酸钠和硫酸铝、硅酸钠与氯化钙、硅酸钠与硫酸亚铁、碳酸钠与氯化钙等;(2)聚合物冻胶类,如聚丙烯酰胺、聚丙烯腈、木质素磺酸盐、生物聚合等形成的各种冻胶,是目前广泛应用的一类;(3)树脂类堵水剂,包括酚醛树脂、环氧树脂、糠醛树脂及热塑性聚合物、聚乙烯、乙烯-醋酸乙烯酯共聚物等;(4)泡沫调剖堵水剂,包括起泡剂和各种添加剂再配合固相成分膨润土、白粉等,如ABS为起泡剂,羧甲基纤维素为稳定剂以膨润土为固相组成调剖剂;还有阳离子表面活性剂堵水技术,甲硅烷堵水技术以及硅酸凝胶堵水技术等。
