克拉玛依油田六中区克下组油藏的原油粘温关系敏感，馏程初馏点低，馏分产率高，其地质特征有利于通过蒸汽的超覆作用来进一步提高注水开发后期油藏的采收率．六中区克下组油藏注水转注蒸汽开发试验的实践表明，在剩余油饱和度较高的部位加密调整，转注蒸汽开发，采收率还能够进一步提高．吞吐一轮后采用间歇汽驱的方法进行热力开采可获得较好的效益． The Kelamayi oilfield has the sensitive viscosity-temperature relationship of the crude oil in the Lower Cretaceous reservoir, the low initial distillation point and high distillate yield, and its geological features are conducive to the further improvement of the oil recovery through the super-action of steam Yield. The practice of water injection and steam injection test of the Lower Cretaceous reservoir in Liuzhong District shows that the oil recovery can be further enhanced by adjusting the density of the remaining oil in the higher part of the reservoir and injecting steam into the area. Huff after a round of intermittent steam flooding method of thermal recovery can get better results.
