摘要： 优选适用于胜利油田孤岛中二中区块普通稠油的聚合物体系及降黏剂体系, 对比采收率及其微观驱 油机理。结果表明, 水驱油的采收率只有4 1. 1%, 微观玻璃刻蚀模型显示存在大片残余油、 油块及油膜。质量分数 为0. 3%X J +0. 2%OP - 1 0复配降黏剂体系在水驱基础上可提高采收率1 8. 6 7%, 主要依靠大油滴变形重新运移, 乳化 作用降低稠油流动阻力, 油滴对油膜的推拉及油膜拉丝剥离作用提高洗油效率。质量浓度为15 0 0m g / LA P - P 5聚 合物驱在水驱基础上提高采收率1 8. 5 5%, 主要是通过增大波及面积及聚合物对油膜和盲状残余油的拉扯作用来提 高采收率, 相比降黏剂驱, 更具优势。

Abstract: Viscosity reducer and polymers system suitable for heavy oil of block Gudao2 of Shengli oilfield were selected so that recovery and microscopic mechanism of viscosity reducer and polymer flooding were compared. The results showed that the ultimate recovery rate of water flooding was only 41.1% and after water flooding there was large presence of residual oil and the film and lump. The recovery rate of XJ and OP10 viscosity reducer flooding after water flooding was increased by 18.67%, which mainly relied on transport of large oil particles after deformation and emulsification to reduce the flow resistance and boosting function of dispersed oil particles to oil film and stripping of the remaining oil by drawing. The recovery rate of APP5 polymer flooding after water flooding was increased by 18.55% by increasing the sweep area and the pull effect on the oil film and blindresidual oil, so polymer flooding compared with viscosity reducer flooding was more valuable.
