摘要
在聚合物驱油中黏度是驱油效率的关键参数，而要控制配注过程中聚合物溶液黏度损失，必须从配注工艺的优化入手．通过理论分析与现场试验相结合的方法，发现常规的配注工艺过程中，在过滤器、注聚泵、静混器、炮眼等主要环节的黏度损失总和高达50％～60％．而根据实际聚合物驱油配注条件与环境情况，通过合理选择设备与参数进行配注工艺过程优化，可使聚合物溶液总黏度损失减少8％～16％．
The viscosity of polymer solution is a key parameter of the polymer flood.It graduately reduces in the process of injection allocation.According to theoretical analysis and field tests,it is found that the viscosity loss produces mainly in filters,polymer injecting pumps,static mixers and shot holes.Sum of the polymer viscosity losses there accounts for 50%～60% of total loss.Through the optimization of injection allocation parameters and the rationally selection of injection allocation equipment,the viscosity loss will is decreased by 8%～16%.
