Abstract
In order to recover casing gas efficiently and safely, a new scheme is proposed to recover casing gas by using an ejector. The influence of the nozzle diameter and the distance from nozzle to throat on the performance of the ejector under different working conditions is studied. The results show that when the nozzle diameter is constant, the inspiratory capacity increases with the increase of water pressure. Compared three nozzles with different diameters, the inspiratory capacity and water flow were approximately linear. Under different working fluid pressures, as the distance from nozzle to throat increases, the ejection ratio of the ejector first increases and then decreases, and there is an optimal distance. In the field test, the gas flow rate of the recovered casing is about 35.27 m3/h.
