摘要
研究的阳离子型弱凝胶调驱剂主要由0.50%的阳离子聚丙烯酰胺+0.03%～0.06%的交联剂组成。使用大量的弱凝胶调驱剂驱替岩心后,油相渗透率恢复值为91.6%,水相渗透率的恢复值仅为15.3%。对岩心封堵率大于90%,突破压力梯度为0.4MPa/cm;现场实验表明投入产出比为1:3.24。
The cationic weak gel profde control and flooding agent （PFA） was composed of cationic polycryamides （0.50%） and cross-linking agent（0.03% -0.06% ）. After flooding with a large amount of PFA, the restorable permeability of oil and water is 91.6% and 15.3%, respectively. The corn water-plugging rate is greater than 90% and the gradient of breakthrough pressure is greater than 0.4 MPa/cm. The ratio of throwing into and producing is 1： 3.24 .
