【摘要】 对淀粉在引发剂作用下与丙烯酰胺的接枝产物进行了研究 ,通过实验确定了最佳反应条件 ,并用红外光谱对产物的结构进行了证明 ,同时在性能上与聚丙烯酰胺进行了比较。该接枝聚合物与交联剂间苯二酚、六次甲基四胺交联成冻胶作为堵水剂 ,通过岩心流动实验发现该冻胶的渗透率较低 ,在现场施工堵水效果较好更多还原

【Abstract】 The graft- copolymer S - AM is composed of acrylamide and water - soluble starch, by a series of experiment we found the optimal reactive condition. The structure of S- AM is verified by Infrared Spectra(IR).And its properties of S- AM is compared with PAM. Based on the graft - copolymer, urotropine and resorcin as cross linking agents synthesize the gelling polymer solution(XD1 ) for water plugging. The water plugging characteristics ofgelled system are determined on artificial core test, and successful used in oil field.更多还原
