基于潜油电泵的同井采注水关键技术研究

Research on the Key Technology of Waterflooding in Same Well Based on the Electric Submersible Pump

在边缘区块和零散小区块油藏资源的开采过程中,传统的注水方式成本较高。因此,提出将潜油电泵改造成注水设备的方案,把同一口井中的水源层的水注入到目的层中。开展同井采注水的关键技术研究,解决了多种关键技术问题,形成了采下注上、才上注下以两种工艺方案,为油田开发提供了一种成本更低、更为可靠的注水方案,具有广阔的应用前景。

In the mining process of edge blocks and scattered area of oil resources, the cost of traditional water injection is high. Therefore, the paper puts forward the modification scheme from electric submersible pump to water injection device to inject the water from water layer to target stratum. The oil production and water injection technology resolves the problems, forms production scheme, providing a cheaper, more reliable water injection scheme which has broad application prospects.
