N2 - The extraction and transportation of crude oil is a typical multiphase flow process. In order to visualize the oil/gas/water distribution, simulation and static tests are carried out in this paper. Electrical capacitance tomography (ECT) and microwave tomography (MWT) carried out static imaging tests of oil-gas two-phase flow and oil-water two-phase flow. Landweber iteration is used as the image reconstruction algorithm of ECT. The simulation results show that the normalized capacitance model, the iteration number and the step length have a certain influence on the ECT image reconstruction. Static tests show that ECT and MWT have a certain complementarity for oil/gas/water distribution. For oil-water flow, the image quality of MWT is better than that of ECT, and for oil-gas flow, the image quality of ECT is better than that of MWT. For a specific flow pattern, MWT image data can be used as the initial value of the ECT image reconstruction algorithm to further improve the accuracy of the ECT image.
