超前注水开发技术是开发低孔、低渗油层的一种有效的方法。超前注水可以合理的补充地层能量,提高地层压力,使油井保持较高的生产能力。本文从水井注水时机、注水强度、采油井流压3个方面对超前注水技术措施进行了研究。该方法在油田实际生产中取得了一定效果,对低渗及特低渗透油田开发实现效益最大化具有重要意义。
Advance water injection development technology is to develop low-porosity, low permeability reservoir of an effective method. Advanced water injection can reasonably replenish the formation energy, raise the formation pressure and maintain the high productivity of the well. In this paper, the water injection timing, water injection strength, oil well flow pressure from three aspects of advanced water injection technology and measures were studied. The method has achieved certain effect in the actual production of oilfields and is of great significance to the development of low permeability and ultra-low permeability oilfields to maximize the benefits.
