摘要
为提高骑16块稠油开发效果,分别进行注蒸汽、蒸汽加N2、蒸汽加CO2、以及蒸汽加N2加CO2吞吐数值模拟研究。确定蒸汽注入量为1000 m3、周期为6;N2注入量为40000 m3、周期为4;CO2注入量为100 t、周期为2;实施上述措施后,周期产油、油汽比都大幅度上升,为提高吞吐阶段采收率、减缓稠油产量递减提供了一条有效途径。
To improve the development effect of heavy oil in Qi16 zone, numerical stimulation research was carried out by steam injection, steam plus N2 injection, steam plus CO2 injection,and steam plus N2 plus CO2.The process conditions were determined as follows： steam injection amount 1000 m3,the cycle 6 times; N2 injection amount 4000 m3,the cycle 4 times;CO2 injection amount 1000 t, the cycle 2 times; After using above measures, periodical oil production and oil gas ratio increased greatly. The study provides an effective method to improve recovery in huff and puff stage, and to slow down heavy oil production decline.
