摘　　要：曙光油田兴隆台超稠油油藏顶水发育,油水层间隔层厚度小,蒸汽吞吐后极易造成水泥环破坏引发窜槽出水。经过大量的室内实验,研制出热稳定性、触变性好的封窜剂,并对施工工艺进行改进,现场应用后能够形成有效封堵,恢复油井产能,提高了管外窜槽顶水治理技术的有效率。The heavy oil reservoir in Shuguang oilfield is developed by cyclic steam stimulation, easy to cause the cement sheath destruction caused by channeling water. Lab experiments show, channeling sealing agent developed with good thermal stability and thixotropy, We improved the tube plugging construction technology, field application shows that the method can effectively block, recover well productivity, improve the water treatment technology of top outside channeling with efficiency.
