| Abstract: |
| Objective To reasonably select wellbore materials and carry out corrosion prevention. Methods Through the autoclave simulation Halfaya oilfield water injection corrosion environment, effects of temperature, pressure and pH on the corrosion law of L80 steel in injection well were studied. Results With the increase of the experimental temperature, the corrosion products of the sample surface were loosen, the protection ability of the samples was worsen, and the corrosion rate of the L80 pipe got higher. With the increase of injection pressure, the corrosion rate became higher, and the local corrosion was worsen. In the acid environment, with the increase of pH, the corrosion rate of L80 decreased, and the main corrosion occurred. The corrosion products are mainly iron oxide and CaCO3 scale. Conclusion The research work provides certain technical support for wellbore material selection and corrosion prevention. |
