摘要: 通过室内实验优选出发泡能力最佳的发泡剂,并对其浓度进行了优选实验,研究了岩心渗透率、岩心含油饱和度及气液比对泡沫阻力因子的影响。利用数值模拟方法,研究了用氮气泡沫控制底水锥进技术。在水锥锥进的生产井中,用高压注入氮气和发泡剂溶液,然后关井焖井一段时间后再开井生产,进行多轮次的氮气泡沫吞吐。利用数值模拟方法,对常规稠油底水油藏氮气泡沫控制水锥技术的开发方式、焖井时间、日排液量、注入方式以及转注时机进行了优化。

Abstract: Foamability of foaming agent was investigated in laboratory.The influential parameters of nitrogen foam resistance factor were optimized by means of laboratory experiments.The effects of core permeability,core oil saturation and gas-liquid ratio on foam resistance factor were discussed.The nitrogen foam anti-water-coning technologies,including multi-periodic injection of nitrogen and foaming agent in the water-coning production wells of the bottom water reservoir,were researched with numerical simulation method.Then the production wells could be open for about one year after shutting for several days.The injection and production parameters of nitrogen foam anti-water-coning technology including injection scheme,shutdown days,daily fluid production rate,size of slug and foam injection time were optimized by means of numerical simulation.

Key words: nitrogen foam, bottom water reservoir, bottom water coning, core permeability, oil saturation, foam resistance factor, numerical simulation
