摘要
为了海上油田首次采用氮气泡沫压锥堵水技术成功实施,通过室内静态性能评价实验优选了适合于该油田的起泡剂BHT和起泡剂最佳反应浓度0.5%,动态性能评价实验证明了BHT起泡剂针对油田目的层有着很高的封堵调剖能力,利用数值模拟技术,结合室内试验结果,优选了施工注入时间和气液比参数,预测并对比了两口井实施氮气泡沫压锥堵水措施前后的生产曲线和三维水锥剖面,结合现场试验结果共同表明,通过向该油田的高含水井注入氮气泡沫,可以有效起到降水增油目的,改善油井生产效果。
For the offshore oilfield successful implementation of N2-foam controlling water cone technology at first time,Through laboratory experiments,static performance evaluation experiment preferred optimal the foaming agent BHT and BHT reaction concentration 0.5％ suitable for the field,dynamic performance evaluation experiment proved that BHT foaming agent had a high profile ability for the purpose layer of oilfield,Using numerical simulation technology,combined with the results of laboratory experiment,preferably the best injection time and gas liquid ratio,to predict and compare the production curves and 3D water cone profile of two wells before and after the measures,combined with the results of the field test Common showed that injecting N2 foam into the high water cut wells,this method could be effective in reducing water production and increasing oil production,making better the effect of single well production.
