内外源微生物复合吞吐技术在常规稠油低效井中的研究与应用
|
摘要
微生物单井吞吐可以有效提高稠油低效井产能,为了强化微生物作用效果,对内外源微生物进行综合研究。利用激活剂体系(糖蜜3 g/L,玉米浆2 g/L,硝酸钠1.5 g/L,磷酸氢二钾1.2 g/L,磷酸二氢钾1 g/L)对地层水进行内源微生物激活,添加嗜热脂肪地芽孢杆菌SL-1进行细菌浓度和乳化能力研究,利用微生物复合吞吐技术对稠油低效井进行单井处理。结果表明,内源微生物被有效激活,细菌浓度峰值为5×108个/mL,乳化指数最高可达95%,产气量最高达260 mL;相比单纯激活内源微生物,添加外源菌后细菌浓度由2×10~8个/mL增加至9×10~8个/mL,乳化指数峰值时间由20 d缩短至15 d。GO7-53X145井和SJSH14-8井取得了显著增油降水效果,为微生物吞吐技术的应用提供了一种新思路。
Microbiological single-well huff and puff may effectively improve the productivity of heavy oil low-efficiency wells. In order to strengthen the microbial action effect, comprehensive study on the indigenous and exogenous microbes were carried out. Indigenous microbes were activated for formation water by using activating agent system(molasses 3 g/L, corn steep liquor 2 g/L, sodium nitrate 1.5 g/L, dipotassium hydrogen phosphate 1.2 g/L, potassium dihydrogen phosphate 1 g/L). Research on bacterial concentration and emulsifying capacity were carried out by adding geobacillus stearothermophilus SL-1. Microbial compound huff and puff technique was used for the single-well treatment of heavy oil low-efficiency wells. The results show that indigenous microbes are activated effectively with the bacterial concentration peak of 5×10~8 cfu/mL and maximum emulsion index of 95% and the gas production is up to 260 mL. Compared with pure activation of indigenous microbes, the bacterial concentration is increased from 2×10~8 cfu/mL to 9×108 cfu/mL and emulsion index peak time is shortened from 20 d to 15 d after adding exogenous microbes. Both well GO7-53 X145 and SJSH14-8 have achieved remarkable effects of increasing oil and decreasing water and provided a new idea for the application of microbial huff and puff technique.
