引言泡沫油，是分散的气泡和稠油的混合物，其形态类似于刮脸膏。储层流体压力降至泡点时，天然气从溶液中释放出来。稠油的粘度和比重限制了气泡相互聚结形成独立相。泡沫油的形成类似于气溶液驱动，只是天然气被圈闭于稠油之内。泡沫油的形成导致出现部分天然气饱和储层，因?
Introduction Foam oils are a mixture of dispersed air bubbles and heavy oils that behave like shaving creams. Natural gas is released from the solution as the reservoir fluid pressure drops to the bubble point. The viscosity and specific gravity of heavy oils limit the coalescence of bubbles to separate phases. The formation of foam oil is similar to that of an aerosol, except that natural gas is trapped in heavy oil. Foam oil formation led to the emergence of some natural gas saturated reservoirs, due to?
