Abstract: According to the production characteristics of Sulige intermittent flowing gas wells, including the periodic changing of casing pressure, gas production and water production, and fluid intermittent production. The process of liquid loading and natural flowing of the intermittent flowing gas wells was studied. The parameter prediction model and dynamic simulation for the gas well were set up, and the production rule was analyzed. The foam drainage and field experiments were compared, and coiled tubing drainage method was proved to be more applicable, which is directional for the dynamic analysis of this kind of wells. The technique provided the reference to extend the natural flowing period of gas wells.
