The invention relates to a water stabilizing device capable of degassing, desanding and stabilizing the produced liquid water content for a production pump for injection-production in the same well. The water stabilizing device is mainly used for solving the problem that a sucking opening of an existing production pump for injection-production in the same well is provided with a plurality of liquid inlet holes in the same plane, thus when the liquid level of an oil sleeve annulus is changed, the wellhead water content is fluctuated significantly. The water stabilizing device is characterized in that the upper part of a water stabilizing device center pipe (18) is connected with a water stabilizing device top cover (19); a plurality of sets of water stabilizing device settling cups (21) areconnected to the position, on the lower part of the water stabilizing device top cover, of the water stabilizing device center pipe (18), and a water stabilizing device settling cup liquid inlet gap(20) is reserved between t
