The utility model relates to a dynamic seal pressure balancing device and belongs to the technical field of oil well logging. A pressure bearing cylinder is connected with a first connector which is connected with a pressure balancing pipe; a first push-pull rod penetrates the central hole of the first connector; the first push-pull rod is connected with a second push-pull rod; a second connector is connected with the pressure balanced pipe; the second push-pull rod penetrates the central hole of the second connector; a third push-pull rod which penetrate the central hole of the second connector is connected with the second push-pull rod; a casing is connected with the second connector. The dynamic seal pressure balancing device has the advantages of achieving dynamic seal pressure balance due to a simple structure, solving the pressure balancing problem under the condition that the push-pull rods are exposed outside and being capable of connecting components such as a water retention meter and a sensor.
