The pursuit of high oil recovery rate has been a persistent objective for oil industry. Pseudomonas sp. LP-7 and Bacillus sp. PAH-2 were isolated from oil-contaminated surface soil samples of an oilfield. The antimicrobial degradation rates(ADRs) of polymers achieved by LP-7 and PAH-2 were evaluated at a temperature of 35 °C in the mineral salt media during the shaken flask trial. The ADRs of copolymer synthesized by using a surfactant with a concentration of 5% could reach 8.4% for PAH-2 and 15.3% for LP-7. The ADRs of copolymer could reach 10.4% for PAH-2 and 21.3% for LP-7,when the polymer concentration was 2 g/L. All results confirmed that the ADRs of copolymers increased with an increasing content of HDDE(capsaicin derivative monomer) in the polymer. The copolymers also manifested excellent antimicrobial degradation performance in the presence of Cu^(2+), Zn^(2+), and Pb^(2+) ions, respectively, which had great potential for applications in enhanced oil recovery.

Effective removal of polycyclic aromatic hydrocarbons （PAHs） from wastewater before their discharge into the environment is an ever pressing requirement. In this study, for the first time, simulated PAHs contaminated wastewater was photocatalytically remediated with graphene oxide （GO） enwrapped silver phosphate as visible light-driven photocatalysts. The GO/Ag3PO4 photocatalysts exhibited superior photocatalytic activity and stability compared with pure Ag3PO4, g-C3N4 and TiO2 （P25）. The degradation efficiency of naphthalene, phenanthrene and pyrene could reach 49.7%, 100.0% and 77.9%, rspectively within 5 min irradiation. The apparent rate constants of photocatalytic degradation of 3 wt% GO/Ag3PO4 composRe photocatalyst were 0.14, 1.21 and 2.46 rain^-1 for naphthalene, phenanthrene and pyrene, respectively. They were about 1.8, 1.5 and 2.0 times higher than that of pure Ag3PO4, and much higher than that of g-C3N4 and TiO2. Meanwhile, the efficiencies of 44.6%, 95.2% and 83.8% were achieved for naphthalene, phenanthrene and pyrene degradation even after 5 times of recycling in the GO/Ag3POa-PAHs photocatalysis system. Reactive species of O2^- and h^＋ were considered as the main partici- pants for oxidizing naphthalene, phenanthrene and pyrene.

By gas chromatogram, six crude oils fingerprinting distributed in four oilfields and four oil platforms were analyzed and the corre- sponding normal paraffin hydrocarbon （ including pristane and phytane） concentration was obtained by the internal standard methed. The normal paraffin hydrocarbon distribution patterns of six crude oils were built and compared. The cluster analysis on the normal paraffin hydrocarbon concentration was conducted for classification and some ratios of oils were used for oils comparison. The results indicated： there was a clear difference within different crude oils in different oil fields and a small difference between the crude oils in the same oil platform. The normal paraffin hydrocarbon distribution pattern and ratios, as well as the cluster analysis on the nomad paraffin hydrocarbon concentration can have a better differentiation result for the crude oils with small difference than the original gas chromatogram.

在考察了国内外内源微生物采油技术研究情况的基础上,采用1#～4#激活剂配方对沾3区块注入水中微生物群落进行了选择性激活,对激活后总菌、有益菌、有害菌的数量及表面张力进行了检测,并进行了室内模拟驱油实验。实验结果表明,1#～4#激活剂配方能有效刺激有益菌的生长,同时对有害菌SRB实现了较为有效的抑制,压力和多孔介质对微生物的生长会产生一定的影响,多孔介质的影响较压力的影响要显著一些,KNO3的激活效果及提高残余油采收率的效果要优于NH4NO3,硝酸盐含量从0.1%到0.2%的增加能增加有益菌的数目,但对采收率的提高作用并不明显。室内模拟驱油实验表明,在水驱基础上内源微生物驱可提高采收率达6%以上。
