Oil gas well trace overflow real time monitoring device

The utility model relates to a well measuring overflow real-time monitoring device belonging to the oil-gas well control and safety and comprising a separator (1), a lower bent pipe (2), an upper direct pipe (3), and the like, wherein the separator (1) is communicated with the lower bent pipe (2) which is communicated with the upper direct pipe (3), the upper direct pipe (3) is provided with a flange (5), the side of the upper direct pipe (3) is communicated with a positioning pipe (4) by using the communicating principle, the side wall of the separator (1) is provided with a hole from which an L-shaped branch pipe is led out, and a liquid level meter (6) is arranged on the branch pipe to monitor the liquid level height of the separator in real-time. When the micro overflow occurs in a well, the liquid level of the separator obviously changes. When the liquid level change of the separator exceeds the limit specified in the well control safety, the monitoring device is triggered to realize the automatic alarm. The utility model is suitable to the real-time and accurate prediction when the micro overflow occurs under the condition of shutting the well, and ensures the well control safety of an oil-gas well.
