Simulation measurement device and method for dynamic corrosion rate of shale gas well shaft

The invention provides a simulation measurement device and method for the dynamic corrosion rate of a shale gas well shaft. The device comprises a liquid injection mechanism, a gas injection mechanism, a gas-liquid separation mechanism and a measurement mechanism, wherein the liquid injection mechanism and the gas injection mechanism are respectively connected with an inlet of the measurement mechanism, an outlet of the measurement mechanism is connected with an inlet of the gas-liquid separation mechanism, and a liquid outlet and an exhaust port of the gas-liquid separation mechanism are respectively connected with the liquid injection mechanism and the gas injection mechanism. Corrosion conditions of different parts of the gas well shaft can be truly simulated. 本发明提出一种页岩气井井筒动态腐蚀速率的模拟测量装置及方法，包括注液机构、注气机构、气液分离机构和测量机构，注液机构和注气机构分别与测量机构的进口相连，测量机构出口与气液分离机构的进口相连，气液分离机构的出液口和排气口分别与注液机构及注气机构相连。本发明能较真实模拟气井井筒不同部位的腐蚀情况。
