Part of shale oil wells in Jimusaer oilfield were short of oil pipelines and needed to be transported by tanker trucks at regular intervals. Due to the lack of single well production, the pump had to be stopped occasionally because the tank was full. The cost of installing a single well measuring device at the wellhead was high, so it was urgent to develop a digital production measurement method to realize real-time production measurement at low cost. Based on the equation of fluid energy conservation and mass conservation, the distribution pressure model of wellbore was established. Combined with the change of wellbore temperature gradient, the calculation model of various physical parameters under temperature and pressure conditions was established. According to the active torque of progressive cavity pump (PCP) rotor and friction torque between fixed rotors, the pressure difference model of PCP inlet and outlet was established. Combining wellhead pressure, pump inlet and outlet pressure, motor parameters, speed and other conditions, coupled with temperature and well fluid parameters, a digital production measurement model of rodless lifting system of electric submersible PCP for shale oil wells was established. Compared with the actual production, the accuracy of the model and the feasibility of the method were verified. The average calculation error was less than 10%, and the minimum error was 5.7%, which was higher than the existing multi-parameter production calculation methods at home and abroad (the average error was more than 20%). The digital production measurement model of electric submersible PCP rodless lifting system based on temperature, pressure and process coupling was innovatively developed with high accuracy, which solved the problem of low cost production measurement for single well of shale oil wells and promoted the digital construction of oil fields.
