Finite Element Numerical Simulation Research on Fractured Horizontal Well’s Productivity

Conventional productivity research method of fractured horizontal wells doesn’t meticulously describe the seepage characteristics of the near wellbore area. Based on the similarity of seepage field and temperature field, and ANSYS finite element software platform, this paper conducts the simulation calculation of the fractured horizontal wells’ productivity, shows the flow of near wellbore area, and analyzes the factors affecting the productivity on fractured horizontal well by using the heat flow field model in the ANSYS software platform. The results show that the larger the angle between fractures and horizontal wells, the higher the production. It is necessary to place the fractures stagger to the greatest extent, and the fracture spacing should be extended as much as possible in actual production. This optimization design of fractured horizontal well has a certain role in guiding.
