海上油田增产技术及效果分析——以渤海某油田为例

摘要

For offshore oilfields,the production increase process is more complicated,and there is a big gap between the stimulation technology used and the onshore oilfields.In view of the increase in production of offshore oilfields,taking an oilfield in Bohai as an example,we first briefly introduced and analyzed the state of the seabed geology in the Bohai Sea,introduced various stimulation technologies used in the field,and introduced and analyzed the effects of the increase in production in detail.The use of oilfield stimulation technology provides advice.Research shows that:In an oilfield in Bohai,four production stimulation measures are mainly used:acoustic waveguide effluent sand technology,microbial mobilization technology,improved fracturing and flooding technology,and hydraulic oscillating flooding technology.In contrast,hydraulic oscillating oil flooding technology is in the Bohai Sea. Regional applications work best.%对于海上油田而言,其增产过程较为复杂,所运用的增产技术和陆上油田相比也存在较大差距.针对海上油田的增产问题,以渤海某油田为例,首先对渤海的海底地质状况作简要介绍和分析,介绍该油田所采用的多种增产技术,并对增产效果进行详细介绍和分析,为海上油田增产技术的运用提供建议.研究表明:渤海某油田主要采用声波导流出砂技术、微生物调驱技术、改善后的压裂驱油技术和水力振荡驱油技术四种增产措施,相比而言,水力振荡驱油技术在渤海区域应用效果最佳.
