孤东油田九区稠油油藏化学蒸汽驱提高采收率技术OA北大核心CSCDCSTPCD
Study on chemical steam flood to enhance recovery ratio of ninth block of Gudong oilfield
稠油油藏在经历了蒸汽吞吐和蒸汽驱开发后,随着注蒸汽井吞吐次数和开采时间的增加,产量递减快、汽窜严重等现象成为开发中后期面临的共性问题,同时也严重制约了该类油藏采收率的大幅提高.化学蒸汽驱在注入蒸汽或热水的同时,加入泡沫体系,利用泡沫体系“堵水不堵油”和“堵低更堵高”的特点,改变注入介质的流动方向,抑制蒸汽超覆和汽窜,补充地层能量,可达到提高稠油油藏采收率和经济效益的目的.根据数值模拟研究和开发实际,设计了孤东油田九区化学蒸汽驱注采参数:泡沫驱后平…查看全部>>
With steam injection times and production time of steamed well increasing, the problem that production declines quickly and serious steam channels become very common, and recovery enhancing of this kind of reservoir become more difficult after the viscous oil reservoir undergoes steam soak and steam flood. Thermal chemical flood is the foam system that is acceded to steam and thermal water which is injected to reservoir, distinguishing feature of foam system…查看全部>>
