The gathering and transportation technology on electrical heating is one of major ways of the gathering and transportation for low permeability and low-yielding oil field, this paper has set up the physical model and mathematical model of the gathering and transportation that is controlled by time. By solving the model, we can determine the start and stop cycle of the gathering and transporting pipelines and dendriform net by electrical heating. And we also have conducted field test, the experiment turns out that the error of the result which is calculated by model compared with actual operational result is less than 1%, the phenomenon meets the requirements of production, the results can be used to determine the start and stop cycle of the gathering and transportation by electrical heating in the process of production.
