Title:
PSEUDOMONAS AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/041062
Kind Code:
A1
Abstract:
Pseudomonas and a use thereof. The preservation number of the pseudomonas is CGMCC No. 22583. The growth temperature of the pseudomonas is 37-45°C; under a medium-high temperature oil reservoir condition, the pseudomonas can be denatured from a non-viscosity fluid to a multifunctional oil-extraction bacterial solution having both surface activity and viscoelasticity, and also has the functions of expanding the swept volume and improving the oil washing efficiency; and the recovery ratio is increased by more than 20% in a physical simulation experiment.
