摘要

直流电场强化采油技术在国际上是一项新技术。试验发现,直流电场能够提高产油量、降低产水量和提高油水比,含水量越高效果越显著。该技术对于提高油田高含水和特高含水开采期的原油采收率效果明显。介绍了直流电场强化油流、增强注水能力、解除地层堵塞技术,探讨了技术机理。

Abstract

Up to now, DC electric field EOR method is a new technology in the world.Test shows that the DC electric field can increase oil production, decrease water production and therefor, improve oil/water ratio. It also shows that the higher water-cut is, the better result can be received. The technology has significant effects for oil recovery at high and extra high water-cut stage. This paper describes how DC electric field enhances oil flow, in creases water injectivity and disposes formation plug. It also gives discussions on this mechanism.
