天然气水合物开采数值模拟中基于mVIEW的水平井井眼轨迹建模

HORIZONTAL WELLBORE TRAJECTORY MODELING BASED ON MVIEW IN NUMERICAL SIMULATION OF NATURAL GAS HYDRATE PRODUCTION

摘要: 针对使用TOUGH+HYDRATE模拟水平井降压开采天然气水合物过程中井眼轨迹的精细刻画给出解决方案，利用mVIEW进行水平井井眼轨迹建模，并进行了模型验证，弥补了模拟器在复杂建模方面的不足，提高模拟器使用效率。由于含井眼轨迹的水平开采模型生产井段在Z方向穿透层位更接近真实的生产情况，因此，含井眼轨迹的水平井开采模型能更好地指导实际生产。

Abstract: 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.
