摘要
本文系统地报导了大庆油田室内筛选和评价菌种的方法，所采用的假单胞杆菌（Ｐｓｅｕｏｄｏｍｏｎａｓａｅｒｕｇｉｎｏｓａ）、野油菜花黄单胞杆菌（Ｘａｎｔｈｅｍｏｎａｓｃｏｍｐｅｓｔｒｉｓ）、地衣芽孢杆菌（ＢａｃｉｌｌｕｓＬｉｃｈｅｎｉｆｏｒｍｉｓ）和５ＧＡ近似于节杆菌（Ｂａｃｔｅｒｏｉｄｅｓ）的配伍菌种，室内实验提高采收率３４．３％，提高残余油采收率６９．８％。
Using microorganisms in-situ fermentation to enhance oil recovery is a new technologyin the petroleum industry. This paper discusses the screening and evaluation of bacterialspecies both in the laboratory and in a pilot test in Daqing oilfield. The bacteria used are Pseuodomonas aeruginosa,Xanthemonas compestris,Bacilluslicheniforms and 5GA,which is most likely to be Bacteroikes.Oil recovery in the laboratorytests were increased by 34.3%, and the residual oil recovery increase was 69.8%。Ahuff-and-puff pilot test on two wells, Dong 6-J22 and Dong 5-J18,which are located in the heavyoil zones in the oil-water transitional zone of eastern Daqing was run in June-July,1990.Af-ter the two wells were shut in for 40 and 64 days,respectively the pressure in the tubingand casing of Well Dong 6-J22 had increased by 1. 6MPa and 1. 9MPa,respectively. Alsodaily liquid production was increased by 15-20t/d,water cut decreased from 94%to 84%,and oil production increased from 3t/d-5-6t/d and lasted about 8 months. After Well Dong5-J18 was shut in for 64 days,liquid production increased,oil production increased from 7.6Vdto 10-11t/d, and gas production increased from 234 m1/d to 547 m1/d and lasted about18 months.
