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。
Peripheral low-permeability oilfield is scattered, with low output and high water injection pressure. The conventional centralized water injection process is adopted, and the investment in water system is relatively large. In order to improve the economic benefits of development, a study on simplifying water system technology has been carried out. In the low-pressure water supply and dispersion water injection three fine filtration short process, to change the set of water injection pump for the dispersed injection pump, change the station outside the high-pressure water supply for low pressure water supply, saving the capital investment in water systems, and more able to adapt to the characteristics of the rolling development of peripheral oil fields for Peripheral low permeability oilfield development provides a new idea.
