摘要
针对郝家油田河11块特高含水期的开采现状,用油藏数值模拟的方法对其提高采收率的可行性及提高采收率技术进行了研究。结果表明,若采用微凝胶调驱方案,增油幅度相对要小一些,但技术上比较简单,容易实施;采用水气交替注入调驱方案,增油幅度相对要大一些,但技术上难度比较大;采用微凝胶与水气交替注入综合调驱方案,实施后开发效果最好,但实施起来难度也最大;在保证不发生气窜的前提下,实施强化注气调驱方案,有利于提高采收率。
In consideration of Extra-high water-bearing production situations in Block Hell of Haojia Oilfield, feasibility study is conducted on enhanced oil recovery and its technique by using the method of reservoir numerical simulation. The result shows that if the project of microgelling profile control and displacement is used, the amplitude of oil production increase is relatively low, but it is simple in technique and easy for operation; if the project of water alternating gas is used, oil production increase is relatively high, but is more difficult in technique. Thus a combined project of microgelling with water alternating gas is used for profile control and displacement with the best result, but it is difficult for operation, too. If no gas channeling is guaranteed , the project of profile control by enhanced gas injection is beneficial for enhanced oil recovery.
