塔河油田稠油潜油电泵在现有管柱结构下，掺稀混配效果差，导致故障停机、躺井频繁、电泵运行寿命短、注采比高、稀油利用率低，增加了生产成本，降低开发经济效益。从掺稀混配效果影响因素分析出发，找到了制约掺稀混配效果的4个因素：混配时间、混配温度、接触面积、搅拌强度，并针对性地提出了治理对策。矿场试验表明：稀油利用率明显提升，平均注采比下降0.22~0.49，经济效益极其显著，下步将进行大规模的推广应用。

Tahe heavy oil submersible electric pump in present pipe column structure leads to poor blend effect and causes many problems such as short downtime, low well electric pump operation frequency, short service life, high injection-production ratio, low oil utilization rate, high production cost and low economic benefit. Four elements controlling the effect of doped dilute mixtures of heavy oil pump are found, including mixing time, mixing temperature, contact surface and mixing strength. The corresponding countermeasures are put forward and applied in field works. The utilizing rate of dilute oil is improved significantly. The average ratio of injection to production declines by 0.22-0.49. Good economic efficiency shows great potential for future application.
