| 摘 要： | 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．

| Abstract: | The Ⅲ conglomerate reservoirs in Kalamayi Oil Field are characterized by high reserve, better physical property and high crude oil viscosity. The avarage oil recovery factor of the reservoirs is only about 23%. They are sensitive to the change of temperature due to the high viscosity. Therefore, the recovery factor of them can be increased by steam injection in the late stage of water injection development. The testing result in Kexia formation, Liuzhong area of the oil field shows that, the oil recovery factor can be increased by thickening flooding network in the areas with high remaining oil saturation, replacing water injection with steam injection in the late stage of water injection dovelopment, and injecting steam intermittently after soaking a cycle. |
