摘　　要：宝浪油田自1996年开始试注开采以来,到目前已初步形成规模,但由于其特殊的储集条件,开采难度非常大,油层伤害严重。通过开展对开发初期宝浪油田储层渗流参数特征的研究,更好地认识了现阶段储层的物性、微观孔隙结构、润湿性、相对渗透率、水驱油效率、储层敏感性、油气水性质等特征,并对油层潜在损害的地质因素进行综合分析。建议新井投注开发前进行近井地带的粘土稳定剂预处理,预防粘土矿物膨胀及微粒运移,注水速度小于4.5m/d;入井流体矿化度应控制在13250～40410mg/L;钻井时应利用屏蔽暂堵技术;在开发中后期宜进行调剖不宜进行聚合物驱。Development of Baolang oilfield is very difficult and reservoir damage is severe due to its specific reser-voir conditions.Better understandings are achieved in respect of reservoir physical properties,micro pore structure,wetting behaviors,relative permeability,water-flooding efficiency,reservoir sensitivity and oil and wa-ter properties on the basis of research on reservoir seep-age flow parameters at the initial stage of development in Baolang oilfield.The geologic factors that cause for-mation damage are also comprehensively analyzed.Clay stabilizer pretreatment should be performed in near well-bore formations before new well intervals being put into production to prevent clay minerals swelling and fine particles migration.Water injection rate should lower than4.5m/d.
