微生物驱油技术在ZJ2延9油藏中的应用及效果评价

Microbial oil recovery technology in ZJ2 Yan9 reservoir of application and evaluation

通过深入剖析ZJ2延9油藏稳产面民临的主要问题,在长庆油田第三采油厂首次提出微生物驱油技术;通过对微生物驱油机理、菌种选育、性能研究及ZJ2延9油藏微生物群落的研究,确定了实验区域。目前,微生物驱油试验第一阶段已经完成,第二阶段也在有条不紊的准备当中;从第一阶段的结果来看,微生物驱油技术改善高渗透层水驱状况,段塞一调驱作用突出,封堵效果较为显著,为后续微生物驱油顺利开展奠定了基础。

Through in-depth analysis of stable reservoir Yan 9 ZJ2 main problem,the third oil extraction plant in the Changqing oil field microbial enhanced oil recovery technology was first proposed;through the mechanism of microbial oil,strain selection,performance,research and extension 9 Oil ZJ2 Possession of microbial communities were studied to determine the experimental area.At present,the microbial oil pilot phase has been completed, the second phase which is also organized preparation;from the first stage results,the microbial oil technology to improve the situation of high permeability of water flooding,flooding slug a prominent role,plugging effect is more significant for the smooth development of subsequent microbial oil basis.
