The company has occupied the leading position in accumulated practical experience and operative technologies in China for many years. At present, it owns over 10 advanced foreign corrosion assessment equipments, Tiandong 5-1 gas field on-line dynamic corrosion testing apparatus and Feng 15 well experimental base for the application of corrosion inhibitor.
At present, the key techniques are mainly:
Aiming at special acid corrosive environments, the company has developed and owned more than 10 corrosion inhibitors that can be used in different environments; it owns relatively complete supporting corrosion inhibitor application technology.
It owns assessment techniques for the electrochemical corrosion of mimetic materials and H2S stress corrosion under the room or field conditions.
It boasts the capacity of on-the-spot rapid corrosion assessment, inspection and monitoring.
It owns the capacity to carry out the research and design of block corrosion prevention scheme.
It can stimulate the complex condition with the highest pressure 70 MPa, the highest temperature 250℃, 15% highest concentration of hydrogen sulfide and 15% highest concentration of CO2.
The Field Test Equipments and Pilot Plant Status:
