An experimental device and method for measuring the slow-release rate of a slow-release tracer. The experimental device includes a liquid supply system, a visual tracer release chamber, a constant temperature system, and a liquid collection device; the liquid supply system includes a liquid storage tank and an adjustable height The liquid storage tank bracket and the liquid flow pipeline; the visual tracer release chamber includes the shell, the inlet port and the outlet port, and the slow-release tracer can be placed inside; the constant temperature system can place the visual tracer inside The cavity is released and a constant temperature is provided; the liquid collection device includes a sample collection bottle and an electronic balance. The experimental device of the present invention uses gravity to provide a stable liquid flow rate, replacing the experimental equipment with complex equipment, high experimental costs, easy interruption of experiments, and harsh experimental environment requirements. It has perfect functions, good stability, and easy operation. The characteristics of low cost and low cost can meet the relevant experimental requirements for the determination of the slow-release rate of the slow-release tracer.
Description
technical field [0001] The invention belongs to the technical field of physical experiments of petroleum and natural gas, and relates to an experimental device and an experimental method for measuring the slow-release rate of a slow-release tracer. Background technique [0002] In the process of oilfield development and production, the oil production and water production of different well sections of the oil well will change with the passage of time. Accurate, real-time and economical acquisition of oil production and water production information at different well sections of the oil well is the key to follow-up production An important prerequisite for system optimization, reservoir transformation, profile control and water shutoff. The slow-release tracer technology for measuring oil well fluid production profiles developed in recent years has the characteristics of low cost, long-term, high efficiency, and does not affect normal production, and has broad application prospe...
