Microscopic oil displacement mechanism of gas producing bacteria
摘要
Abstract
Morphology and flow characteristic of remaining oil in the displacement process were observed with a microscopic visual simulation model. Microscopic displacement effect of various remaining oil by the gas producing bacteria was quantitatively analyzed. After the injection of gas producing bacteria into the model,crude oil viscosity was reduced and oil mobility was enhanced. The effect on the cluster and columnar remaining oil was obvious and final oil recovery was increased by 22%. Compared with conventional gas drive,the sweep volume was enlarged and the displacement efficiency was improved in the active migration of gas producing bacteria. Therefore,a higher oil recovery was obtained.关键词
