Abstract:

This paper introduces the microbe-applied oil recovery mechanism, technical progress and implementation in Jing’an oilfield, and based on the oilfield geology selects some microbes to enhance oil recovery on site with the test results indicting that the microbe-applied technology is applicable in low-permeable and fissured sandstone reservoir in Jing’an oilfield, gaining a higher oil recovery. This technology is of a good developing viability.

Key words:
