摘　　要：分析了新疆油田公司中、低渗油藏注水井的堵塞机理及解决的方法,通过室内试验和研究,找出了适合中、低渗油藏使用的缓速酸酸液配方,并研制了无污染的层内转向剂,使得在进行化学增注时不同渗透性的目的层均能得到解堵增注的效果。通过两年来在新疆油田公司采油三厂和宝浪油田的使用,达到预期效果。In this paper, the receiptof retared acid adapted for the middleand low permeability reserviors was achieved by the experiment in doors and analyzingthe block-mechanism of the middle and low permeability reserviors' water injection well in Xinjiang Oilfield Company. At the same time, the diversion agentof interlamination was developed, which can dissolve the plugand increase injection in the different permeable intended zones when carrying the technique of chemic augmented injection. It has been achieved the anticipated purpose by the applying in the ThirdProduction Plant in Xinjiang Oilfield Company and Baolang Oilfield Company.
