注氮气技术在稠油油田的应用

Application of Nitrogen Injection Technology in Heavy Oil Field

为了提高稠油油田开采的效率,采取注氮气开发的技术措施,降低稠油的黏度,提高稠油井的采收率。冷采稠油油田注入氮气,能够降黏开采,提高氮气的波及系数,改善蒸汽驱及蒸汽吞吐的开发状况,达到稠油开采的技术要求。

In order to improve the ef?ciency of heavy oil?eld exploitation,technical measures for nitrogen injection development are adopted to reduce the viscosity of heavy oil and improve the recovery of heavy oil wells.Injecting nitrogen into the cold-harvested heavy oil?eld can reduce the viscosity mining,increase the sweep coef?cient of nitrogen,improve the development of steam?ooding and steam stimulation,and meet the technical requirements for heavy oil exploitation.
