In order to alleviate the water shortage in the development of oil and gas resources, horizontal wells are often used to exploit groundwater resources, but there is little analysis on the factors affecting the water intake of horizontal wells. Therefore, the numerical model is used to simulate the horizontal well mining mode and explore the influence of horizontal well layout direction, burial depth, pipe length and well pipe permeability on the water intake effect. The results show that considering the water intake efficiency and construction difficulty, the optimal horizontal well layout direction should be laid along the incoming water direction, and the location should be located in the upper layer of Luohe Formation as far as possible. The recommended pipe length and well pipe permeability are 800 m-1 000 m and 0.15, respectively, and the corresponding production volume is 1 368 m3/d-2 389 m3/d. The research results have important guiding significance for alleviating the shortage of water resources in the development of oil and gas resources in the eastern region of Longdong and formulating reasonable development strategies of water resources.
