摘　　要：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。Low concentration HPAM/AlCit aqueous systems are principally a solution/colloid rather than a gel. In laboratory core experiements at 50℃ with a linked polymer solution(LPS) of polymer concentration 150 mg/L and of HPAM to Al mass ratio 20∶1, both increase in injection pressure (blockage formation in pores) and enhancement in oil recovery are observed. In a field test conducted at a production unit of Gaosheng oil production factory in Liaohe, 3 110 m 3 of LPS (0.012 7 PV) is injected into a water injection well with flow rate 30 m 3/d and this results in notable increase of oil production and decrease of water cut in one of the production wells. The field results are discussed. A mechanismic explanation is given.
