| 摘 要： | 针对吞吐开采后期稠油油藏压力大幅下降、注汽汽窜等问题,研究了集洗油、调剖、降粘三效合一的高温复合驱油体系。采用FCY泡沫剂作为三效合一的高温复合驱油体系的发泡剂,利用稳态法测定了泡沫的封堵效果,通过渗流实验考察了渗流速度对封堵压差的影响及泡沫作用下气体渗流机理,并根据渗流机理实验结果,建立了阻力因子泡沫渗流模型。模型的计算结果与实验结果具有较好的一致性,模型在描述泡沫剪切变稀特性的同时,还考察了临界含水饱和度、毛管数指数等各参数对气体渗流的影响,为稠油油藏蒸汽泡沫驱提供了理论支持。

| Abstract: | High temperature composite flooding systems with oil-washing,profile-controlling,viscosity-reduction functions were developed.It is used to solve the severe problems which were faced in the late development stage such as heavy oil reservoirs pressure declining greatly and ineffective steam channeling in high permeability zones,etc.FCY high temperature multifunctional foamer was researched as foaming agent of high temperature composite flooding systems,and plugging capacity of foam was measured by stable met... |
