一种新型单液法复合调剖剂的研究

Study on A New Type Profile Control Agent for Single-fluid Method

摘要: 在硫酸亚铁与脲醛树脂组合成的单液法复合调剖液中加入一定量的尿素并适当提高脲醛树脂溶液伯ｐＨ值，可以显著提高其稳定性。这种复合调剖剂克服了单一调剖剂的特点，为高温深井的调剂，提高原油产量提供了一种新型单地调剖剂。

Abstract: Addition of certain amount of urea and appropriate increase of the pH value of urea formaldehyde solution in the composite profile control agent consisted of ferrous sulfate and urea-formaldehyde resin may result remarkable increase in its stability.It ha
