摘要/Abstract

摘要： 准噶尔盆地克浅10井区稠油油藏经过20余年的高速高效注蒸汽开发,进入“双高”阶段,成为“双负”油藏,油井大面积关停。为探究该井区复产潜力,通过实验评价、油藏工程及数值模拟方法等手段,对蒸汽驱环境下菌群特征进行研究,明确微生物采油体系。结果表明:克浅10井区蒸汽未波及区富含采油功能菌,具备微生物内源动用的基础,微生物采油体系为内源菌+6-2菌株+激活剂。现场试验采用反五点井网的方式开采,累计产油8 750 t,基本运行费由蒸汽驱的2 057元/t降至577元/t。该研究可为浅层稠油提质增效、提高采收率及稠油绿色低碳开发储备接替技术提供借鉴。

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 studied through experimental evaluation,reservoir engineering analysis and numerical simulation,and a microbial enhanced oil recovery system was established.The results show that the steam-unswept zone in the Keqian 10 well Area is rich in functional microorganisms for oil recovery,providing a basis for the activation and utilization of indigenous microorganisms.The microbial enhanced oil recovery system is indigenous microorganisms+Strain 6-2+an activator.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 establishing replacement technologies for green and low-carbon development of heavy oil.

Key words: microbial enhanced oil recovery system, heavy oil reservoir, microbial community structure, enhanced oil recovery, the Keqian 10 Well Area
