Abstract

The relationship between multiphase flow and corrosion is described in this paper. Influences of the multiphase flow mode, phase transition temperature, CO2 partial pressure, H2S pratial poessure, pressure drop and flow rate on corrosion are analyzed. Mathematical calculation models of multiphase flow in oil and gas field mainly are the limited velocity calculation of erosion, erosion prediction model and corrosion inhibitor adsorption model. These models can predict the corrosion in scene. And the corrosion monitoring technology, anti-corrosion measures are described in depth, and some suggestions are proposed.
- multiphase flow,
- corrosion law,
- control measure
