摘　　要：为解决强1块低渗透裂缝油藏部分层段水淹严重的问题,针对其地质特点,研究了各组分浓度对堵水剂体系堵水性能参数的影响,并进行了浓度参数优选。结果表明,交联剂、引发剂、稳定剂浓度对堵水体系初始黏度、初凝黏度、初凝时间、成胶强度均有不同程度上的影响。In order to solve the serious water-out problem in the low permeability fractured reservoir of Qiang 1 block, the effect of concentration of each component on the water shutoff performance of the plugging agent system was studied, and the concentration parameters were optimized. The results show that the effects of cross linking agent concentration, initiator concentration and stabilizer concentration on the initial viscosity, initial setting viscosity, initial setting time and gelation strength of the water shutoff system are different.
