摘要(Abstract)：

研究分析了多种微生物对胶态分散凝胶 (CDG)体系的作用。结果表明 ,多种微生物 (如腐生菌、硫酸盐还原菌、铁细菌、乙酸菌等 )都会对CDG体系成胶过程中及成胶后的粘度产生影响 ,使体系粘度迅速下降。在此基础上 ,对杀菌剂与CDG体系之间的关系做出了初步评价。认为在CDG体系中加入适当浓度的杀菌剂 ,能够保证CDG体系在地层厌氧条件下的稳定性。该研究结果为矿场试验中应用CDG体系进行调剖驱油提供了实验依据
This paper illustrates the effect of different anaerobic or facultive microbial on the Colloid Dispersal Gel (CDG). It also studies the interaction between the bactericide and the Colloid Dispersal Gel . The result indicates that several kinds of bacteria(including sulfate reducing bacterial, iron bacterial, acetic acid bacterial) can affect the formation process and the viscosity of CDG, and decrease the viscosity of CDG.The impact can be eliminated by using proper bactericide, so the reseach provides theoretical and practical evidence for the pilot test of profile with Colloid Dispersal Gel .
