| 摘 要： | 产能低、注水开发困难、采收率低是深层低渗油藏开发面临的主要问题。为探索特低渗透油藏有效的开发方式和提高采收率途径,针对濮城油田沙三中油层深层低渗的特点,进行了系列驱替实验。研究了水驱油、气驱油特征及其对采收率的影响,分析了影响驱替特征的因素。研究结果表明,较大的驱替速度和净覆压使驱油效率和采收率降低;特低渗油藏气驱采收率明显高于水驱采收率,采取注气开发可以提高其开发效果和采收率。这一研究成果对濮城油田经济、高效开发低渗透油藏具有重要的指导意义。 |

| Abstract: | The main problems of deep zone and low permeability reservoir are low production capacity, flooding development difficulty and low recovery factor. A series of displacement tests have been done in order to explore the effective development mode and enhanced recovery methods aimed at the characteristics of Middle Es3 low permeability reservoir in Pucheng Oilfield. This paper studies the characteristics of displacing oil by water and displacing oil by gas and the influence factors on recovery and displacement... |
