摘　　要：榆树林油田储层粘土矿物含量较高 ,各种注入条件和施工条件都会对该储层造成相应的伤害 ,应采取相应的防护措施。为防止速敏的发生 ,储层的注水速度应控制在临界流速 (1 0mL min)以下 ;在油井转注时 ,可先注入 1 0 9PV的含粘土稳定剂的水溶液。酸敏实验表明 ,该储层用 8%的盐酸溶液处理时 ,不发生酸敏 ,所以该储层可用盐酸进行处理 ,以提高产量或注入量 ;注入阴离子表面活性剂配置的活性水后再注入地层水 ,不能增加地层水的渗透率。The reservoir of Yushulin Oil Field in Daqing has a high content of clay. A lot of injection conditions and operation conditions may cause damage on this reservoir. So relative protection measure should be used. In order to avoid rate sensitivity, the water injection rate should be controlled below the critical flow rate(1 07 mL/min). In order to avoid water sensitivity, when oil well is converted into injection well, 1 09 PV of water solution containing clay stabilizer can be initially injected. Acid sensitivity experiment shows that, when this reservoir is processed with hydrochloric acid solution of 8%, there is no acid sensitivity. So it can be processed with hydrochloric acid to increase oil production or water injection rate. This study has a conductive significance for the development of Yushulin Oil Field.
