摘　　要：井楼油田高浅3区已进入蒸汽吞吐后期开发阶段,蒸汽吞吐开发效果变差,为改善开发状况,拟采用氮气和降黏剂辅助蒸汽吞吐开发技术。通过模型建立,对氮气、降黏剂注入量、注入方式、注入速度、注入时间等参数进行了模拟优化,优化结果表明,井楼油田高浅3区采用氮气、降黏剂辅助蒸汽开采技术可有效改善开发效果,增油效果明显。Gaoqian-3 area of Jinglou oilfield has entered the later stage of steam stimulation development and the steam stimulation effect became poor.In order to improve the development status,the nitrogen-assisted chemical viscosity reducing technology has been proposed to be adopted.Through models establishment,the simulation optimization on the injected volume of nitrogen and viscosity reducer,on the injection pattern,injection speed and injection time have been carried out.The results show the nitrogen-assisted chemical viscosity reducing technology is good and it can effectively improve the development effect and obviously increase oil.
