| 摘 要： | 在对胜利油田中一区油藏流体分析的基础上，模拟油藏高温（65℃）高压（10 MPa）环境，研究了葡萄糖、玉米淀粉水解液、小麦淀粉、羧甲基纤维素钠作为碳源的不同激活剂体系对中一区7N11井产出水中内源菌激活效果的影响。实验结果表明：不同碳源会显著影响油藏内源菌的生长周期、菌群结构及代谢活性，综合评价淀粉水解液为碳源的激活效果较好。在此基础上用淀粉水解液配制的激活剂进行了物理模拟驱油实验，增油效果显著，30 d后采收率提高幅度可以达到4.8%。

| Abstract: | Based on the reservoir fluid analysis for Zhongyi block of Shengli Oilfield, the effect of different carbon sources, including glucose, corn starch hydrolysates, wheat starch and sodium carboxymethyl cellulose, on activating indigenous microorganisms in the water from District 7N11 Wells was studied at high temperature (65℃)and high pressure (10 MPa)of reservoir conditions.The results showed that the carbon source could influence significantly growth cycle, community structures and metabolic activities, and the overall effect of corn starch hydrolyzates was better than others.The physical simulation experiments were carried out using the corn starch hydrolysates activator.The results indicated that oil production increased significantly, and the raise of oil recovery rate could reach 4.8% after 30 days’ activation. |
