微生物采油增产机理及应用

Mechanism and Application of the Microbe Production Enhance.

将微生物注入油藏 ,滞流在油藏岩石孔隙中的微生物发生生化反应 ,可产生表面活性剂、溶剂、醇类、可溶气、酸和聚合物等。这些微生物的代谢产物通过降低原油表面张力和粘度 ,可提高岩石孔隙介质中原油的流速 ,增强洗油和驱油效果 ,提高原油采收率。该技术在国内。

Results including surfactant,solvent,alcohol,soluble gas,acid,polymer and so on may be produced by the biochemistry reaction of the microbe injected and occluded in reservoir pores.Oil surface tension and viscosity may be decreased as well as porous flow velocity increased by the product of microbe metabolism.The effects of clean out and displacement of the oil is improved so as to enhance the oil recovery.A benefit has been acquired by the technology from the application in the tertiary oil recovery in old oilfields at home and abroad.
