Study and application of a microbial enhanced oil recovery system for the heavy oil reservoir in the Keqian 10 Well Area
摘要
Abstract
After more than 20 years of high-rate and high-efficiency steam-injection development,the heavy oil reservoir in the Keqian 10 well Area of the Junggar Basin has entered the"dual-high"stage and become a"dual-negative"reservoir,resulting in the shutdown of oil wells over a large area.To investigate the potential for resuming production in this well area,the characteristics of microbial communities under steam-flooding conditions were stud-ied through experimental evaluation,reservoir engineering analysis and numerical simulation,and a microbial en-hanced oil recovery system was established.The results show that the steam-unswept zone in the Keqian 10 well Ar-ea is rich in functional microorganisms for oil recovery,providing a basis for the activation and utilization of indige-nous microorganisms.The microbial enhanced oil recovery system is indigenous microorganisms+Strain 6-2+an acti-vator.The field test was conducted using an inverted five-spot well pattern,achieving a cumulative oil production of 8 750 t;basic operating costs decreased from RMB 2 057/t under steam flooding to RMB 577/t.This study provides a reference for improving the quality and efficiency of shallow heavy oil development,enhancing oil recovery,and es-tablishing replacement technologies for green and low-carbon development of heavy oil.关键词
