| 摘 要： | 从海上油田开发实际需求出发,针对南堡35-2油田储层非均质特征、储层物性和流体性质特点,利用室内实验方法,对以有机铬为交联剂的交联聚合物溶液的成胶性能、流动能力、粘弹性进行了测定,对交联聚合物溶液的封堵和驱油效果进行了评价。结果表明,有机铬交联聚合物溶液能够在南堡35-2油田地质条件下形成"分子内"交联体系,注入油藏后可达到增大孔隙流动阻力、增加注入压力的作用;注入时机、交联聚合物注入量、聚合物浓度、原油粘度和物理模型等参数将影响封堵和驱油效果。

| Abstract: | According to the psactical needs in offshore-oilfield development and the reservoir heterogeneity,petrophysics and fluid property in NB 35-2 field,the gelation,flow ability and viscosity-elasticity are measured for the chromium-organic cross-linked polymer solution by laboratory methods,and its effects of blocking and oil displacement are evaluated.The results indicated that the chromium-organic cross-linked polymer solution can form an "intra-molecular" cross-linked system under the geologic conditions in NB 35-2 oilfield,increasing the flow resistance and the injection pressure after injected into the reservoir.There are several parameters that can affect the blocking and oil displacement of the polymer solution,including injection time,injection amount and concentration of the polymer solution,oil viscosity,the physical model and so on. |
