| 摘 要： | 通过室内二维平面模拟实验,用五点法布井方式的填砂平板模型,在模拟生产井完全水淹的基础上,模拟热油吞吐的生产过程.实验中设计的模型能较好地模拟均质油藏,采用可视化模型直观地再现了注油前后生产井周围多孔介质中油水的微观分布状态.根据各周期注油量和采油量,以及模拟生产井周围油水的分布情况,从油藏渗流规律和驱油理论2方面综合分析,提出了劈水疏油的概念,并利用这一概念对热油吞吐提高油井产量的原因进行了分析,指出劈水疏油是热油吞吐提高油井产量的主要机理,热效应和解除井底有机垢堵塞对增产也有辅助效果.

| Abstract: | Through the 2-D planar simulation lab experiment,and by means of sand-filling model of five-point well pattern,and based on the complete water flooding of producer,the production process of cyclic steam stimulation is simulated herein.The model designed in the lab may simulate the homogeneous reservoir,and can visualize the microscopic distribution of water and oil in the porous media surrounding the producer before and after injection by means of visualization micro-model.The conception of water splitting ... |
