特性 调剖剂profile contrcl agent能调整注水地层吸入剖面的物质叫调剖剂。注入油层的水,大部分(80%一90%)为高渗透层所吸收,注入剖面很不均匀。为了发挥中、低渗透层的作用,提高注入水的波及系数,就必须调整注水井的注入剖面。主要有沉淀型调剖剂,如碳酸钠一三氯化铁、硅酸钠.硫酸亚铁、硅酸钠一氯化钙;凝胶型}l }J }}J,如水解聚丙烯酞胺和铬公甲醛配戌:树脂型调剖}J。如聚氨醋类、糠醇树脂等。
为此,最近中国石油勘探开发研究院采油工程研究所提出了一种无机凝胶涂层调剖剂(WJSTP) ,该调剖剂与油藏高矿化度地层水反应形成与地层水密度相当的无机凝胶,通过吸附涂层,在岩石骨架表面逐渐结垢形成无机凝胶涂层,使地...
