为解决聚合物驱注入井分层注入问题，设计了地面试验装置，测定了不同流量聚合物溶液流经不同孔径水嘴前后的粘度损失以及水嘴进出口导角前后的粘度变化情况，找出了不同孔径水嘴与粘度损失的关系． 水嘴整形后， 聚合物溶液的粘度损失比整形前降低近１／３ ，直径１０ ｍ ｍ 的水嘴损失比较大，直径１３ ｍ ｍ 的水嘴损失小于１ ｍ Ｐａ·
In order to solve the injection problem of polymer flooding injection well, a ground test device was designed to measure the viscosity loss before and after flowing different polymer flow through the nozzle and the viscosity changes before and after the inlet and outlet of the nozzle The relationship between different aperture faucets and viscosity loss. After the nozzle is reshaped, the viscosity loss of the polymer solution is reduced by nearly one-third compared with that before shaping. The nozzle with a diameter of 10 m m has a relatively large loss, and the nozzle with a diameter of 13 μm has a loss of less than 1 m Pa ·
