FIELD: well production.
SUBSTANCE: present invention relates to a downhole logging probe made with the possibility of placing pump rods on a single line in a column. The downhole monitoring device located in line with the pump rod column contains a case located in line with the pump rod column, a set of sensors located inside the case and made to perceive at least one of the operating conditions of the pump rod column and the surrounding operating conditions of the pump rod column. The power source and electronic circuit for data collection, storage and management are located inside the case. The true-time pulse generator located inside the case is designed to assign time stamps to the collected downhole data and synchronize with the system generator of clock pulses located at the top. The set of sensors, an electronic circuit for data collection, storage, and management, and a power source are interconnected. The set of sensors contain sensors designed to measure the tension, compression, and torque in the pump rod column. The electronic circuit is sealed and it contains an accelerometer and electronics designed to collect, process, and store data. The system for monitoring at least one of the tension, compression, torque, temperature, pressure, position, speed, vibration and acceleration during logging contains at least one downhole monitoring device, a pump rod column and a rod pump.
EFFECT: achieved technical result is maximizing the productivity of the well by optimizing the ground system and detecting mechanical failures of the well equipment.
