【Abstract】 Polymer flooding is a tertiary oil recovery for enhancing oil recovery, but it is difficult to sink polymer suspension particles, and the effect of temperature on polymer flooding is obvious. In view of these, a slot-type stirring tundish was designed, the structure and working mechanism of the device were elaborated as well as the design of the main components, the device can realize temperature control and pressure control, and can measure the viscosity of polymer in real time. By using the device, the multiplex flooding experiments were carried out, the reliability of the device in the polymer viscosity measurement was verified, the device can be used to explore the separated injection or the combined injection, so as to realize the oil displacement effect of different polymers and optimize the development of the layer system, which has far-reaching significance in the development of oil and gas.更多还原
