Abstract
A piston pressure device includes a gas concentration-regulating piston pressure device and a high temperature autoclave. In the gas concentration-regulating piston pressure device, the proportion and concentration of corrosive gases can be accurately adjusted, intermediate gases can be stored and filled into the high temperature autoclave according to experimental needs, and an actual corrosion process in oilfield is accurately simulated. Meanwhile, the corrosive gases can be supplemented in real time during the experiment, and dynamic gas distribution in a high-temperature high-pressure corrosion experiment process is realized. The present invention has the advantages as follows: the piston pressure device is resistant to high temperature and high pressure, corrosion-resistant, simple in structure and convenient to operate; the concentration and proportion of the corrosive gases are accurately controlled to be invariable in the high-temperature high-corrosion experiment process; and reliability of high-temperature high-pressure corrosive experimental results is increased.
