摘　　要：克拉玛依油田六中区克下组油藏原油粘温反应敏感，馏分产率高，注水开采效果较差，转注蒸汽后取得了较好的效果，预计采收能够提高27．9％，使最终采收率达到47．4％，它的成功开发为克拉玛依油田Ⅲ类砾岩油藏注水转注蒸汽的开发提供了良好的依据，据有广泛的应用前景。Lower Karamay reservoir in middle area of District No. 6, Karamay Oilfield, is characterizedby high sensitivity of crude viscosity - temperature idependency and high fraction production rate,resulting in poor effects by waterflooding. After using steam injection process, good result has beenachieved with estimation of oil recovery effciency by 27. 9 % increased,.reaching final recovery ra-tio of 47. 4 %. This can provide successful basis for Type Ⅲ conglomerate reservoirs in Karamayfield developed by waterflood process to be converted into steam injection production. Using steaminjection process in high - water - cut stage has an extensive application prospect.
