Description

technical field [0001] The invention relates to a polymer solution dissolved oxygen removal system, in particular to a novel intelligent high-efficiency polymer solution oxygen removal system which combines vacuum pumping and nitrogen gas removal technology. The invention belongs to the technical field of polymer solution oxygen removal. Background technique [0002] When evaluating polymer performance under high temperature reservoir conditions, the thermal stability of polymer solution is often used as a key index. The thermal stability of the polymer solution refers to the stability of the viscosity of the polymer solution over a long period of time under the conditions of reservoir temperature and salinity. In previous experiments, polymer solutions that meet the conditions were often used to seal after deoxygenation, and then put them in an oven with oil reservoir temperature, measure the viscosity of the polymer solution from time to time, calculate the viscosity rete...

Problems solved by technology

[0004] At present, the polymer solution usually adopts the method of nitrogen gas to remove oxygen. This method is simple and easy to operate, but the oxygen removal rate is low, and the final oxygen content in the solution cannot be controlled.

The utility model patent technology with the application number 2012202482185 combines vacuum pumping technology and nitrogen filling technology to invent a visual device for oxygen removal of polymer solution, which can improve the oxygen removal rate of polymer solution, but the device is all manually controlled. The oxygen removal rate can only be judged based on experience, which makes it difficult to control the final oxygen content in the solution, often resulting in inaccurate experimental data
