摘　　要：外围低渗透油田分布零散、产量低、注水压力高 ,采用常规集中注水工艺 ,水系统投资较大。为提高开发的经济效益 ,开展了简化水系统工艺的研究。在低压供水分散注水三级精滤短流程中 ,改集中注水泵为分散注水泵 ,改站外高压输水为低压供水 ,节省了水系统基建投资 ,更能适应外围油田滚动开发的特点 ,为外围低渗透油田的开发提供了一条新的思路。Using the routine conecntrating waterflood technology to periphery low permeability oilfield needs bygger investment.In ofder to raise the developing economic result,the authors make a research on simplifying the technology of water system.On the basis of process flow of low pressure water supply,scattering waterflood and 3*.stage fine filtrating ,the scattered injecting pumps change into concentrated ones,the outstation high pressure water transferring change into low pressure one so that the investment of capital construction are largely saved and is more suiting the characteristics of rolling development of periphery oilfield.
