Since the decline in conventional oil production, the research and development of unconventional oil are very important. Tight oil has the following characteristics. First, the property of different layers of tight oil is different, and the second is the amount of fluid in the production cycle is variational. To determine the tight oil gathering and transportation scheme, the entire production cycle is divided into three stages. The two schemes of heating and water injection are analyzed by simulating and comparing their Gathering safe distance and energy-consumption. The results show that water injection is better than heat gathering and transportation technology in these two aspects. So as to ensure the normal operation of gathering system and save operating costs, we choose water injection gathering and transportation technology.
