弱凝胶与微生物调驱联作技术的研究

Profile control and oil displacement by joint function of weak gel and microbe

依据二次采油与三次采油理论 ,结合油田生产实际 ,探索研究了弱凝胶与微生物调驱联作技术的可行性。实验结果表明 ,弱凝胶与微生物菌液具有良好的配伍性 ,具备技术联作的可操作性 ,该项技术将会成为二次采油向三次采油过渡的技术先导 ,有广阔的发展前景和应用价值 。

The feasibility of profile control and oil displacement by joint function of weak gel and microbe is studied with the combination of secondary and tertiary recovery theory and oilfield production practice. Experimental result shows that there is good compatibility and operability between weak gel and bacterial liquid. This will be a transitional technique from secondary to tertiary recovery, has a bright future and provides basis for developing tertiary recovery technologies.
