摘要: H油田MB储层是以孔隙为主的碳酸盐岩储层,注水开发是主要的开发方式,注入水的水质影响着油田开发的效果。对H油田的注入水水质标准进行研究,主要采用岩心驱替实验及动态腐蚀实验得出注入水中的悬浮物粒径中值、悬浮物含量、油量、细菌含量等主要控制指标。结果表明,悬浮物粒径中值≤2.5 μm;悬浮物质量浓度≤10 mg/L;油质量浓度≤15 mg/L;腐生菌(TGB)含量≤100 个/mL,铁细菌(IB)含量≤10 个/mL,硫酸盐还原菌(SRB)含量≤10 个/mL;该结果为H油田注入水水质标准提供了实验依据,亦为类似区块的注水水质研究提供了参考。

Abstract: MB reservoir in H oilfield is mainly carbonate reservoir with pores,and water injection development is the main development method.The quality of injected water affects the effect of the oilfield development.The injected water quality standard of H oil field was studied,and the main control indexes such as the median particle size,suspended matter content,oil content and bacteria content of the injected water were obtained by core displacement experiment and dynamic corrosion experiment.The results showed that the median particle size index of suspended solids was less than or equal to 2.5 μm.Suspension content index was no more than 10 mg/L,oil content indexwas no more than 15 mg/L,the content of saprophyte (TGB) should be no more than 100 per mL,the content of iron bacteria (IB) should be no more than 10 per mL,and the content of SRB should be no more than 10 per mL.The results provide experimental basis for water injection quality standards in H oilfield,and also provide reference for research on water injection quality in similar areas.
