In order to solve the problem of water intrusion seriously affecting the development of each production well in TY gas field, a numerical model was established with reference to well X in TY gas field to study the characteristics of water intrusion in TY gas field, and four sets of water control and production increase experiments were completed, including elastic extraction experiment, water plugging experiment, side drilling experiment and combined water plugging and side drilling process experiment, which were verified by physical experiments on this basis. The results show that different water control and production enhancement measures have different effects, among which the combination of water plugging and lateral drilling process has the best effect, which can increase the gas production by 84.1%, and the error between the physical experiment results and the numerical simulation results is 7.7%.
