本文介绍了聚丙烯酰胺 /柠檬酸铝交联聚合物溶液深部调剖矿场试验。结果表明 ,低浓度的交联聚合物溶液可堵塞水驱形成的水通道 ,使驱替液进入含油层 ,提高注水井注入压力 ;交联聚合物溶液进入高渗层可产生微观溶液流改向作用 ,具有调剖、驱油功能 ,能增加生产井的产油量 ,降低产液量和含水率 ;交联聚合物溶液可不断向地层深部推进 ,起到深部调剖、液流改向作用 ;通过调整聚合物浓度、注入方式可控制注入压力、改善驱油效果 ,提高原油采收率。
This paper introduces the polyacrylamide / aluminum citrate cross-linked polymer solution deep profile control field test. The results show that the low concentration of cross-linked polymer solution can block the water channel formed by water flooding, make the displacement fluid enter the oil-bearing layer and increase the injection pressure of the injection well. The cross-linked polymer solution enters into the high permeation layer to produce micro- Role, with profile control, flooding function, can increase the production of oil production and reduce liquid production and water content; cross-linked polymer solution can continue to advance deep into the formation, played a deep profile control, flow redirects ; By adjusting the polymer concentration, injection mode can control the injection pressure, improve the displacement effect, improve the recovery rate of crude oil.
