调剖剂在温度78℃,地层水矿化度37226mg/L的条件下,老化稳定性高。室内并联岩心流动实验结果表明,调剖剂吸水剖面改善率接近90%,其对高低渗透层的剖面调整能起到明显的作用,调驱前,低渗透层吸水很少,注入调驱剂后,高渗透层的吸水能力大大降低,低渗透层的吸水能力发生了明显变化,很快得以启动且渗透率极差越大,剖面改善越好;单管岩心流动实验表明,调剖剂在岩心中的突破压力梯度为15.22MPa/m,连续注水12.68PV压力变化小耐冲刷性能良好。
Profile control agent at a temperature of 78 ℃, formation water salinity 37226mg / L under the conditions of aging and high stability. The experimental results of indoor parallel core flow show that the improvement rate of water absorption profile of profile control agent is close to 90%, which plays a significant role in the profile adjustment of high and low permeable layers. Before water transfer, the low permeability layer has little water absorption, , The water absorption capacity of the high permeability layer is greatly reduced, the water absorption capacity of the low permeability layer has changed obviously, it can be activated very quickly and the permeability is very poor, and the profile improvement is better. The single-core core flow experiment shows that the profile control agent in the rock The heart of the breakthrough pressure gradient of 15.22MPa / m, continuous water injection 12.68PV pressure change small erosion resistance good.
