| titleOfInvention | Environment-friendly oil-water well reservoir wellbore blockage removal agent |
| abstract | The present invention provides an environment-friendly oil-water well reservoir wellbore blockage removal agent, comprising the following main components: sodium diethylenetriaminepentaacetate, ethyl acetate, alkyl glyceryl ether sulfonate, glucoside, chelating agent, sulfamic acid, and water. In the present invention, glucoside is used together with alkyl glyceryl ether sulfonate and sulfamic acid, so that not only is the corrosiveness low, but also the product performance at high temperature is stable. Moreover, the performances such as the speed of dissolving composite blockage and reservoir permeability restoration rate are significantly improved. In the environment-friendly oil-water well reservoir wellbore blockage removal agent of the present invention, the addition of sodium diethylenetriaminepentaacetate can significantly increase the foul dissolving rate of the wellbore blockage removal agent and restore the reservoir permeability. |
