The measurement of oil well production is an important task in oilfield production management. Accu. rate and timely measurement of oil well production has important guiding significance for mastering reservoir con. ditions and formulating production plans. Through the research and analysis of the existing measurement technol. ogy, this paper selects the single well measurement technology suitable for the measurement of the screw pump and the rodless pump, and develops the corresponding single well online weighing and measuring device. After rigorous laboratory experiments and field tests, the device is reliable in operation, high in measurement accuracy, and the measurement error is within ±5%, which satisfies the requirement of ±10% of the maximum accuracy of measurement accuracy in the oil and gas gathering and transportation process design specification for oil and gas field surface engineering. The research and application of the single well online measurement technology and de. vice can simplify the oilfield gathering and transportation process, reduce the ground construction cost, and solve the problem that the effective single well online measurement method for the screw pump, the rodless pump and the like, and fill the technical blank.
