从三叠系长6油藏产出污泥中分离出一株具有较强驱油能力的优势菌株G1-1,并对其进行了驱油能力测试。研究了注入参数对微生物提高采收率的影响,通过岩心模拟驱油实验优选出最佳微生物注入段塞为0.3~0.45 PV ,最佳注入速度为现场水驱速度0.48 m/d。采用分段塞注入增油效果最佳,采收率增值可达15.24%。实验结果表明,所选用菌种与油层有良好配伍性,控水稳油效果明显。

Superiority strains G1-1 was obtained from the sludge samples collected from the Triassic Yanchang 6 reservoir and the oil-displacement capacity was tested .The impact of injec-tion parameter on microbial enhanced oil recovery was researched .Through the artificial core flooding experiments ,the best microbial injection slug was optimized to be 0 .3-0 .45 PV ,and the best injection speed was water flooding speed in field trial of 0 .48 m/d .The effect of section in-creasing oil by plug injection was the best ,which could improve oil recovery up to 15 .24% .The experiment results show that the selected strains have good compatibility with reservoir and obvi-ous stabilizing oil production by water control effect .
