Abstract: At present, the production line used for testing the method of artificial heat boiler using steam injection operation, this method there is a large man-made error and lag, to a large extent affected the dry steam injection test accuracy In order to solve this problem, with the heavy oil thermal recovery process supporting technology development, water / steam two-phase flow of the dynamic monitoring of technological development, there has been two-phase flow computer measurement and control Computer technology is a two-phase flow measurement and control expenditure by standard two-phase flow measurement device with the flow of dry degrees as the basis for the summary and the development of a new technology can be effectively measured parameters of the steam injection, steam injection automatic detection the operation of the At the same time, its simple and intuitive man-machine interface, can be used to meet the requirements of the Key words: two-phase flow; steam injection parameters; boiler steam injection; stem degrees; flow
