摘　　要：针对克拉玛依油田稠油沥青质组分所占比例大的特点,通过室内菌种筛选,选育出适合克拉玛依稠油的微生物菌种,该菌种能够显著降解稠油中的沥青质。微生物吞吐矿场试验结果表明:六口油井措施有效率100%,累计增油936.883t,取得明显的经济效益,该技术为新疆油田稠油蒸汽吞吐后进一步提高采收率提供了一种工序简单、安全环保的新方法。Asphaltene in viscous oil components constitute the majority in Kelamayi Oilfield, one suitable microbien is selected to effectively treat viscous oil in Kelamayi by means of indoor bacteria research method and the bacteria can remarkably decrease as-phaltene of viscous oil. Field test effect of microbial huff and puff showed that the treats are 100% effective so that six wells produce more oil and the cumulative incremental oil is 936. 883 t, acquiring obvious economic benefits. The technology provides a simple and friendly new method to environment to enhance oil recovery for Xinjiang Oilfield after viscous oil steam huff and puff.
