Structure Design of Swirl Flow Tool in the Natural Gas Well

Abstract:

In order to solve the problem of gas recovery by liquid drainage, the swirl flow tool was designed. Firstly, the whole structure of the swirl flow tool was introduced. The swirl flow tool includes three units, i.e. the screw basement, restrictor and setting mechanism. The characteristic of the tool is that there does not exist a gap between the outer diameter of the swirl flow tool and the inner diameter of the oil tube. Then, its work principle, setting process and deblocking process were discussed. The application results for the swirl flow tool in the oilfield show that the casing pressure is decreased by 7.0%-17.6% and the average gas production per day is increased by 7.4%-11.9%.
