摘要
涠10-3油田生产层有L_3~Ⅱ和L_3~Ⅲ两个油组,因两油组之间的隔层质量差,投产后L_3~Ⅲ油组释放的天然气窜到L_3~Ⅲ油组,致使L_3~Ⅱ油组油相渗透率低,且形成次生气顶,影响了该油组生产。因此,在溶解气驱阶段,对生产压差、油气比、采油速度等开发指标适当调整和控制,会使开发效果提高一步。并在地层压力不低于饱和压力15—20%时,给油藏补充能量最适时。生产试验表明,注水及注天然气单井吞吐是有效的增产措施。
The productive intervals of Wei 10—3 oil field consists of L_3~Ⅱ and L_3~Ⅲ units.Because the barrier between the two units is poor,After production,released gas migrates from L_3~Ⅲ unit to L_3~Ⅱ unit resulted in oil-phase permeability lower,formed secondary gas cap in L_3~Ⅲ unit and influenced L_3~Ⅱ unit production. Therefore,during solution gas driving thg development effect will be improved by adjusting and controling the producing pressure drop,gas-oil ration ,and production rate etc.Supply energy to reservoir is timely when formation pressure is not 1 5～20% lower than saturation pressure.The production test shows that single—well huff and puff by water injection and gas injection is a effective measure of increasing production.
