This paper proposed a solution to the wellbore trajectory modeling in the process of using the TOUGH+HYDRATE to simulate the horizontal well depressurization of natural gas hydrate. The mVIEW is used to model the horizontal wellbore trajectory, and the model verification is carried out to make up the deficiencies of the simulator in complex modeling and improve the efficiency of the simulator. The horizontal well model with wellbore trajectory can better guide actual production because it is closer to the real production situation in the Z direction.
