摘要

摘要: 根据河南油田生产实际需求,通过室内研究,对适用于高温油藏的交联聚合物调剖剂成胶性能、注入性能及封堵能力进行了评价。研究结果表明,溶解氧含量在0.5 mg/L以下时,交联聚合物调剖体系温度为85~100℃时成胶黏度可控,耐温性能及注入性能良好,具有很好的长期热稳定性,适用于高温油藏的油藏条件;有机醛交联聚合物调剖体系在广泛的渗透率范围内注入性良好,能够进入地层深部。交联聚合物溶液更容易进入高渗透率层,对非均质油层具有选择性进入能力,对于高渗透岩心的封堵效果比对低渗透岩心的封堵效果更明显。

Abstract: According to actual demands of Henan oilfield, the performance evaluation of gelling properties, injection performance and sealing ability of crosslinked polymer profile control agent which is suitable to high temperature reservoir profile were evaluated through laboratory researches. The results indicate that the cross–linked polymer viscosity is controllable in the temperature variationranging from 85 to 100℃ when the dissolved oxygen content is less than 0.5 mg/L. The cross–linked polymer has a good heat resistance performance and splendid property of injection, so it is applicable to high temperature reservoir. The organic aldehyde crosslinked polymer profile has a good injection ability in a wide range of permeability and can penetrate into the deep strata. The crosslinked polymer solution is easier to enter the high permeability layer, and it has selective entry capability for heterogeneous reservoirs. Compared with low permeability cores, it has a more obvious blocking effect in high permeability cores.
