摘　　要：在硫酸亚铁与脲醛树脂组合成的单液法复合调剖剂中，加入一定量的尿素并适当提高脲醛树脂溶液的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缺点，为高温深井的调剖、提高原油产量提供了一种新型单液法调剖剂。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 has overeome shortcomings of the single profile control agent and has advantage of high stability, high temperature - resistane, high strength, efficient plugging and low cost. It furnishes a new type profile control agent for single-fluid method for the profile control of high-temperature deep-well and oil yield increase.
