Focusing on the requirements of horizontal well production testing,the limitations of traditional production logging technology and the insufficient data required to establish a digital oil field,a quantum dot tracer production testing technology was proposed to monitor dynamic oil and water production of horizontal wells.A quantum dot tracer model was established in the transient monitoring stage and steady-state monitoring stage,and the flow of sampling,detection and interpretation of the quantum dot tracer were proposed.The application of a horizontal well demonstrates the effectiveness of the intelligent tracer technology in monitoring the oil and water production in each section of the horizontal well,and demonstrates that the quantum dot tracer monitoring technology has the function of continuous monitoring of horizontal well production performance.The intelligent tracer production test and interpretation technology can monitor the production of a well,discover the water production section and provide refined data for the establishment of digital oil fields.
