The invention provides an online water content analyzing device for an oil well mouth, and relates to the technical field of oil field measuring meters. The device can separate out a gas phase dissolved in a well mouth mixed solution before the water content is detected, and therefore the measuring precision of the water content of well mouth liquid is improved. Meanwhile, the detection period is shortened, and the real-time metering of the water content of the well mouth liquid is ensured. The online water content analyzing device for the oil well mouth comprises a swirling gas-liquid separator, the inner wall of the swirling gas-liquid separator is provided with a swirling channel, a medium induction pipe is arranged on the inlet side of the separator, a gas phase eduction pipe is arranged on the top of the separator, an exhaust control valve is arranged at the gas inlet end of the gas phase eduction pipe, a liquid phase eduction pipe is arranged at the bottom of the separator, a capacitive water content metering module and a data conversion module are installed on the liquid phase eduction pipe, and the gas phase eduction pipe and the liquid phase eduction pipe are connected with a medium return pipe.
