吉林油田两个产聚合物菌区块连续注入试验效果分析

Evaluation on the effect of the continuous in injection experiment of the polymer producting bacteria in Jilin Oilfield

A菌在储层中代谢非水溶性聚合物, 能够降低油井产出液含水, 提高单井产量。该菌在吉林油田已进行了 4年的连续注入试验, 从矿场先导性试验到扩大试验, 经历了清水营养基伴随注入到污水营养基伴随注入, 取得了良好的试验效果。

Bacteria A metabolizes non-water soluble polymer, decreases the water cut in the produced fluid in oil wells,and increases the single well production. This kind of bacteria has been tested for 4 years through a continuous injection in Jilin Oil Field. From pilot test to expanded test,and from fresh nutrient base to produced nutrient base accompanied injection, it has a good test effect.
