System for monitoring flowing bottomhole pressure in real time

The utility model discloses a system for monitoring flowing bottomhole pressure in real time, and belongs to the field of development of oilfields. The system comprises a sensor, a pressure meter, a transmission unit and a processing unit, wherein the sensor is used for measuring load capacity and displacement of a sucker rod of a pumping unit, the pressure meter is used for measuring a casing pressure value of an oil well, the transmission unit is used for transmitting the load capacity and the displacement measured by the sensor and the casing pressure value measured by the pressure meter, the processing unit is used for receiving the load capacity, the displacement and the casing pressure value transmitted by the transmission unit and processing the received load capacity, the received displacement and the received casing pressure value so as to obtain the flowing bottomhole pressure, the sensor and the pressure meter are electrically connected with the transmission unit respectively, and the transmission unit is electrically connected with the processing unit. According to the system, use of an expensive working fluid level real-time monitoring device is avoided, and equipment cost is remarkably reduced.
