摘要： 新疆油田公司采油三厂与美国的NPC微生物公司合作,对两种不同类型的低渗透油藏进行了微生物处理,试验结果一西区中三叠统砂砾岩油藏的增产效果明显高于一区石炭系裂缝性基岩油藏。本文就此分析了低渗透油藏的渗透率、孔隙度、矿化度及渗流机理的差异对微生物工艺的影响,并提出了针对特殊油藏,须适当调整措施方式,做出最优化的处理方案及引入时时监测技术的建议。

Abstract: The microbial treatment and pilot test of two different types of low permeability reservoirs were conducted by cooperation of No.3 Production Plant of Xinjiang Oilield Company with NPC Mictobial Company. USA. The results showed that the glutenite reservoir of Middle Triassic in District No, 1 west had mueb more responses than that of the fractured basement reservoir of Carboniferous in District No.1. This pa-per analyzes the effect of diferences among permeability, porosity, salinity and percolation mechanism for low permeabilily reservoirs on micro-bial recovery process, proposes some proper regulation measures for special reservoirs, and makes suggestions for optinmum processing progrurn and introducing real-time monitoring techniques.

Key words: MEOR, EOR, reservoir type, pilot lest
